Abstract
PURPOSE OF REVIEW This article reviews recent advances in ultrasound elastography in diagnosing and evaluating the normal nongravid uterus and the infertile uterus in the gynecologic patient. RECENT FINDINGS Focusing on the most recent primary literature, studies have demonstrated new findings among a breadth of gynecologic clinical settings. Studies in the nongravid uterus have found that menopausal status, age, and menstrual phase have not been associated with changes in uterine tissue stiffness. Focusing on myometrial disease, there have been conflicting data regarding the ability to distinguish uterine fibroids from adenomyosis. One area of expanding research surrounding uterine elastography includes the infertile population, where ongoing studies attempt to provide a predictive model using shear wave elastography (SWE) in patients undergoing in-vitro fertilization. SUMMARY Ultrasound elastography has become an increasingly studied and utilized tool in assessing physiologic and pathologic processes in the field of gynecology. Evaluating tissue stiffness through strain and SWE can serve to improve diagnosis of various uterine and cervical lesions, as well as prognosticate outcomes after fertility treatments. This growing area of research will continue to establish the role and application of ultrasound elastography into clinical practice.

Prevalence of adenomyosis features in women scheduled for assisted reproductive treatment, using the Morphological Uterus Sonographic Assessment group definitions. Acta Obstet Gynecol Scand 2024; 103:1142-1152. [PMID: 38410091 PMCID: PMC11103150 DOI: 10.1111/aogs.14812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2023] [Revised: 02/04/2024] [Accepted: 02/05/2024] [Indexed: 02/28/2024]
Abstract
INTRODUCTION Studies that use standardized ultrasonographic criteria to diagnose adenomyosis in subfertile women are needed. These would improve the understanding of the disease burden and enable further studies on its impact on fertility and assisted reproductive treatment (ART) outcome. The aim of this study was to determine the prevalence of different features of adenomyosis in women scheduled for their first ART, diagnosed at two (2D) and three-dimensional (3D) transvaginal ultrasonography (TVUS) using the revised Morphological Uterus Sonographic Assessment (MUSA) group definitions. MATERIAL AND METHODS This was a prospective, observational cross-sectional study of subfertile women aged 25 to ≤39 years, that were referred to a university hospital for their first ART between December 2018 and May 2021. Of 1224 eligible women, 1160 women fulfilled the inclusion criteria and consented to participate in the study. All women underwent a systematic 2D and 3D TVUS examination. The primary outcome was the presence of direct and indirect features of adenomyosis, as proposed by the MUSA group. Secondary outcomes were to describe the ultrasonographic characteristics of the different features, as well as any difference in the diagnostics at 2D or 3D TVUS and any association with clinical characteristics such as endometriosis. RESULTS At least one direct or indirect feature of adenomyosis was observed in 272 (23.4%, 95% confidence interval [CI] 21.0-25.9) women. Direct features that are pathognomonic for the disease were observed in 111 (9.6%, 95% CI, 7.9-11.3) women. Direct features were visible only at 3D TVUS in 56 (4.8%, 95% CI 3.6-6.1) women, that is, 56/111 (50.5%) of women with at least one direct adenomyosis feature. Direct features were more common in women with endometriosis (OR 2.8, 95% CI 1.8-4.3). CONCLUSIONS We found than one in 10 women scheduled for ART had direct features of adenomyosis at ultrasound examination. The present study suggests that the use of 3D TVUS is an important complement to 2D in the diagnostics of adenomyosis. Our results may further improve the counseling of women scheduled for ART and enables future studies on the impact of different features of adenomyosis on subfertility, ART results and obstetric outcomes.

Adenomyosis diagnosis among adolescents and young women with dysmenorrhoea and heavy menstrual bleeding. Reprod Biomed Online 2024; 48:103768. [PMID: 38432071 DOI: 10.1016/j.rbmo.2023.103768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 12/03/2023] [Accepted: 12/05/2023] [Indexed: 03/05/2024]
Abstract
RESEARCH QUESTION What is the prevalence of adenomyosis at ultrasonography among adolescents and young women reporting dysmenorrhoea and/or heavy menstrual bleeding (HMB)? DESIGN This observational cohort study involved adolescents and young women referred for dysmenorrhoea and/or HMB to the Adolescent Medicine Unit at Careggi University Hospital, Italy. Patients with endometriosis and bleeding disorders were excluded. Transvaginal ultrasonography or transrectal sonography using a transvaginal probe was performed. The myometrium was described according to the Morphological Uterus Sonographic Assessment criteria. Details of baseline characteristics, clinical data and symptoms were collected. The presence of sonographic features of adenomyosis and the association between imaging findings and clinical symptoms were evaluated. RESULTS The cohort included 95 patients aged between 13 and 25 years, referred for dysmenorrhoea (88.4%), HMB (23.2%) or both (13.7%). According to the MUSA criteria the sonographic diagnosis of adenomyosis was made in 27.4% of patients, with the diffuse type the most prevalent. Uterine wall asymmetry, hyperechoic intramyometrial islands, translesional vascularity and an interrupted junctional zone were the most common features. Patients with imaging findings of adenomyosis had significantly higher rates of HMB than those with a normal myometrial appearance (38.5% versus 17.4%, P = 0.030). In addition, the coexistence of dysmenorrhoea and HMB was significantly associated with adenomyosis (odds ratio 5.68, 95% confidence interval 1.65-19.5). CONCLUSIONS Adenomyosis may be diagnosed among teenagers and young women referred with dysmenorrhoea and/or HMB. The clinical presentation is relevant for the diagnosis, with HMB alone and HMB plus dysmenorrhoea significantly associated with the sonographic identification of adenomyosis.

Magnetic Resonance Imaging-Based Classification Systems for Informing Better Outcomes of Adenomyosis After Ultrasound-Guided High-Intensity Focused Ultrasound Ablating Surgery. J Magn Reson Imaging 2024; 59:1787-1797. [PMID: 37671487 DOI: 10.1002/jmri.28943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Revised: 07/22/2023] [Accepted: 07/24/2023] [Indexed: 09/07/2023] Open
Abstract
BACKGROUND A referenced MRI-based classification associated with focused ultrasound ablation surgery (FUAS) outcomes is lacking in adenomyosis. PURPOSE To identify an MRI-based classification system for informing the FUAS outcomes. STUDY TYPE Retrospective. POPULATION Patients with FUAS for adenomyosis, were divided into a training set (N = 643; 355 with post-FUAS gonadotropin-releasing hormone/levonorgestrel, 288 without post-FUAS therapy) and an external validation set (N = 135; all without post-FUAS therapy). FIELD STRENGTH/SEQUENCE 1.5 T, turbo spin-echo T2-weighted imaging and single-shot echo-planar diffusion-weighted imaging sequences. ASSESSMENT Five MRI-based adenomyosis classifications: classification 1 (C1) (diffuse, focal, and mild), C2 (intrinsic, extrinsic, intramural, and indeterminate), C3 (internal, adenomyomas, and external), C4 (six subtypes on areas [internal or external] and volumes [<1/3 or ≥2/3]), and C5 (internal [asymmetric or symmetric], external, intramural, full thickness [asymmetric or symmetric]) for FUAS outcomes (symptom relief and recurrence). STATISTICAL TESTS The optimal classification was significantly associated with the most subtypes of FUAS outcomes. Relating to the timing of recurrence was measured using Cox regression analysis and median recurrence time was estimated by a Kaplan-Meier curve. A P value <0.05 was considered statistically significant. RESULTS Dysmenorrhea relief and recurrence were only associated with C2 in training patients undergoing FUAS alone. Compared with other subtypes, the extrinsic subtype of C2 was significantly associated with dysmenorrhea recurrence in the FUAS group. Besides, the median dysmenorrhea recurrence time of extrinsic subtype was significantly shorter than that of other subtypes (42.0 months vs. 50.3 months). In the validation cohort, C2 was confirmed as the optimal system and its extrinsic subtype was confirmed to have a significantly shorter dysmenorrhea recurrence time than other subtypes. DATA CONCLUSION Classification 2 can inform dysmenorrhea relief and recurrence in patients with adenomyosis undergoing FAUS only. Itsextrinsic subtype was associated with an earlier onset of dysmenorrhea recurrence after treatment. EVIDENCE LEVEL 3 TECHNICAL EFFICACY: Stage 5.

Uterine peristalsis in women affected by adenomyosis: A step towards functional assessment. Int J Gynaecol Obstet 2024; 165:666-671. [PMID: 38205860 DOI: 10.1002/ijgo.15299] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 11/24/2023] [Accepted: 11/29/2023] [Indexed: 01/12/2024]
Abstract
OBJECTIVE The non-pregnant uterus shows an intrinsic contractility pattern, actively involved in early reproductive processes. Uterine contractility is characterized by endometrial waves that originate from the junctional zone and varies throughout the menstrual cycle due to fluctuations in the concentrations of hormones. The aim of this study was to compare the uterine contractility patterns in the periovulatory phase in a group of patients with isolated adenomyosis and a group of healthy women using transvaginal ultrasound (TVUS). METHODS From March 2019 to March 2021, we enrolled consecutive nulliparous patients in the periovulatory phase of the menstrual cycle, divided in patients with isolated adenomyosis (group A, n = 18) and healthy patients in the control group (group B, n = 18). Patients who met the inclusion criteria underwent TVUS for the study of uterine contractility: the uterus was scanned on sagittal plane for 3 min and all the movies were recorded. Then, static images and video were evaluated offline and the uterine contractility patterns were defined. RESULTS The patients belonging to the study group had a higher incidence of painful symptoms (dysmenorrhea, 6.11 ± 2.81 vs 1.39 ± 2.17; chronic pelvic pain, 2.56 ± 3.01 vs 0.39 ± 1.04) and a larger uterine volume (137.48 ± 117.69 vs 74.50 ± 27.58 cm3; P = 0.04). Regarding the uterine contractility, a statistically significant difference was observed about the retrograde patterns (group A, 27.8% vs group B, 72.2%, P < 0.01) and opposing (group A, 38.9% vs, group B, 5.6%, P = 0.02). CONCLUSION The study confirms the presence of altered uterine peristalsis in the periovulatory phase in patients with adenomyosis. The abnormal uterine peristalsis could lead to both structural and functional changes, which are the basis of the clinical manifestations of adenomyosis and the perpetuation of the anatomical damage.

Quantitative ultrasound measurement of uterine contractility in adenomyotic vs. normal uteri: a multicenter prospective study. Fertil Steril 2024; 121:864-872. [PMID: 38199285 DOI: 10.1016/j.fertnstert.2024.01.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 01/04/2024] [Accepted: 01/04/2024] [Indexed: 01/12/2024]
Abstract
OBJECTIVE To evaluate uterine contractility in patients with adenomyosis compared with healthy controls using a quantitative two-dimensional transvaginal ultrasound (TVUS) speckle tracking method. DESIGN A multicenter prospective observational study took place in three European centers between 2014 and 2023. SETTING One university teaching hospital, 1 teaching hospital and 1 specialised clinic. PATIENTS A total of 46 women with a sonographic or magnetic resonance imaging diagnosis of adenomyosis were included. 106 healthy controls without uterine pathologies were included. INTERVENTION Four-minute TVUS recordings were performed and four uterine contractility features were extracted using a speckle tracking algorithm. MAIN OUTCOMES MEASURES The extracted features were contraction frequency (contractions/min), amplitude, velocity (mm/s), and coordination. Women with adenomyosis were compared with healthy controls according to the phase of the menstrual cycle. RESULTS Throughout the different phases of the menstrual cycle, trends of increased amplitude, decreased frequency and velocity, and reduced contraction coordination were seen in patients with adenomyosis compared with healthy controls. These were statistically significant in the late follicular phase, with a higher amplitude (0.087 ± 0.042 vs. 0.050 ± 0.018), lower frequency and velocity (1.49 ± 0.22 vs. 1.68 ± 0.25 contractions/min, and 0.65 ± 0.18 vs. 0.88 ± 0.29 mm/s, respectively), and reduced contraction coordination (0.34 ± 0.08 vs. 0.26 ± 0.17), in the late luteal phase, with higher amplitude (0.050 ± 0.022 vs. 0.035 ± 0.013), lower velocity (0.51 ± 0.11 vs. 0.65 ± 0.13 mm/s), and reduced contraction coordination (0.027 ± 0.06 vs. 0.18 ± 0.07), and in the midfollicular phase, with decreased frequency (1.48 ± 0.21 vs. 1.69 ± 0.16 contractions/min) in patients with adenomyosis compared with healthy controls. During menses, a higher pain score was significantly associated with lower frequency and velocity and higher contraction amplitude. Results remained significant after correcting for age, parity, and body mass index. CONCLUSION Uterine contractility differs in patients with adenomyosis compared with healthy controls throughout the phases of the menstrual cycle. This suggests an etiologic mechanism for the infertility and dysmenorrhea seen in patients with adenomyosis. Moreover, it presents new potential therapeutic targets and diagnostic markers.

Accuracy of MRI in predicting deep myometrial invasion in endometrial cancer and the influence of leiomyoma, adenomyosis and the microcystic elongated and fragmented tumour pattern. J Med Imaging Radiat Oncol 2024; 68:235-242. [PMID: 38377045 DOI: 10.1111/1754-9485.13622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 12/29/2023] [Indexed: 02/22/2024]
Abstract
INTRODUCTION The most common form of endometrial cancer is Type 1 endometrioid adenocarcinoma. Depth of myometrial invasion is the most important prognostic factor correlating with overall patient survival. The objective was to investigate how accurate magnetic resonance imaging (MRI) is in predicting the depth of myometrial invasion in preoperative assessment, and the influence of leiomyoma and/or adenomyosis, or microcystic, elongated and fragmented (MELF) pattern of invasion on MRI diagnostic performance. METHOD Retrospective audit of 235 endometrial cancer patients from the regional Gynaecology Oncology multidisciplinary meeting at Auckland City Hospital, between January 2020 and January 2021. Radiologist assigned stage was compared to histopathology. Presence of leiomyoma, adenomyosis and MELF pattern evaluated followed by analysis under a Biostatistician's supervision. RESULTS Overall MRI diagnostic accuracy for depth of myometrial invasion was 86%. For deep myometrial invasion, MRI had a sensitivity of 72% and specificity 91%. Out of the misreported 32/235 cases, 16 demonstrated fibroids and/or adenomyosis leading to a sensitivity of 57% and specificity 93% for deep invasion, compared with 94% and 74% respectively in the population without, demonstrating statistical significance. Thirty seven cases with MELF pattern of invasion showed a sensitivity of 81% and specificity 80% for deep invasion, compared with 63% and 92% respectively in the group without, demonstrating no statistical significance. CONCLUSION MRI assessment of the depth of myometrial invasion in endometrial cancer has high accuracy. In the presence of background uterine fibroids/adenomyosis, pre-operative MRI accuracy of evaluating deep invasion shows a statistically significant reduction.

Optimized treatment parameter by computer simulation for high-intensity focused ultrasound treatment of uterine adenomyosis: Short-term and long-term results. PLoS One 2024; 19:e0301193. [PMID: 38547090 PMCID: PMC10977802 DOI: 10.1371/journal.pone.0301193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 02/29/2024] [Indexed: 04/02/2024] Open
Abstract
This study aimed to investigate the efficacy and safety of using optimized parameters obtained by computer simulation for ultrasound-guided high-intensity focused ultrasound (HIFU) treatment of uterine adenomyosis in comparison with conventional parameters. We retrospectively assessed a single-institution, prospective study that was registered at Clinical Research Information Service (CRiS) of Republic of Korea (KCT0003586). Sixty-six female participants (median age: 44 years) with focal uterine adenomyosis were prospectively enrolled. All participants were treated with a HIFU system by using treatment parameters either for treating uterine fibroids (Group A, first 20 participants) or obtained via computer simulation (Group B, later 46 participants). To assess the treatment efficacy of HIFU, qualitative indices, including the clinically effective dysmenorrhea improvement index (DII), were evaluated up to 3 years after treatment, whereas quantitative indices, such as the nonperfused volume ratio and adenomyosis volume shrinkage ratio (AVSR), on MRI were evaluated up to 3 months after treatment. Quantitative/qualitative indices were compared between Groups A and B by using generalized linear mixed effect model. A safety assessment was also performed. Results showed that clinically effective DII was more frequently observed in Group B than in Group A (odds ratio, 3.69; P = 0.025), and AVSR were higher in Group B than in Group A (least-squares means, 21.61; P = 0.001). However, two participants in Group B developed skin burns at the buttock and sciatic nerve pain and required treatment. In conclusion, parameters obtained by computer simulation were more effective than the conventional parameters for treating uterine adenomyosis by using HIFU in terms of clinically effective DII and AVSR. However, care should be taken because of the risk of adverse events.

Abstract
OBJECTIVE To compare assisted reproductive technologies (ARTs) outcomes between fresh vs. freeze-all strategies in infertile women affected by adenomyosis. DESIGN A single-center observational study. SETTINGS University hospital-based research center. PATIENTS Adenomyosis-affected women undergoing blastocyst embryo transfer after in vitro fertilization and intracytoplasmic sperm injection between January 1, 2018, and November 31, 2021. The diagnosis of adenomyosis was based on imaging criteria (i.e., transvaginal ultrasound and/or magnetic resonance imaging). INTERVENTION(S) Women who underwent a freeze-all strategy were compared with those who underwent a fresh embryo transfer (ET) strategy. MAIN OUTCOME MEASURE(S) Cumulative live birth rate (LBR). RESULTS A total of 306 women were included in the analysis: 111 in the fresh ET group and 195 in the freeze-all group. The adenomyosis phenotype (internal diffuse adenomyosis, external focal adenomyosis, and adenomyoma) was not significantly different between the two groups. The cumulative LBR (86 [44.1%] vs. 34 [30.6%], respectively), and the cumulative ongoing pregnancy rate (88 [45.1%] vs. 36 [32.4%], respectively) were significantly higher in the freeze-all group compared with the fresh ET group. After multivariate logistic regression analysis, the freeze-all strategy in women with adenomyosis was associated with significantly higher odds of live birth compared with fresh ET (odds ratio = 1.80; 95% confidence interval = 1.02-3.16). CONCLUSION The freeze-all strategy in women afflicted with adenomyosis undergoing ART was associated with significantly higher cumulative LBRs. Our preliminary results suggest that the freeze-all strategy is an attractive option that increases ART success rates. Additional studies, with a randomized design, should be conducted to further test whether the freeze-all strategy enhances the pregnancy rate in adenomyosis-affected women.

Abstract
OBJECTIVE To describe a case of extrauterine adenomyoma (EA) and review all the cases of EA in the literature. METHODS Pubmed/MEDLINE, Embase, and Google Scholar from 1807 to December 2022. All studies reporting the histologic diagnosis of an EA. We collected the following data: patient's age, size and location of adenomyoma, presence of endometriosis and adenomyosis, past gynecologic treatment, symptoms, diagnostic imaging, surgical intervention, alternative/adjuvant treatment, associated malignancy, and follow up. RESULTS Sixty-seven studies with 85 patients were included. Pain was the most frequent symptom (69.5%). Among diagnostic examinations, ultrasonography was used in 60 out of 81 reported cases, with several radiologic features described. EA was located inside the pelvis in 77.6% of patients. Adnexa were the most frequent site of the disease (24, 28.2%). History of endometriosis or adenomyosis was described in 35 patients (35, 41.2%). Uterine tissue morcellation was reported in 6 of the 85 patients (7.1%). Associated malignancy was detected in 9 out of 85 patients with available data (10.6%). There were two recurrences of disease. CONCLUSION Specific imaging features of EA are yet to be described in the literature. History of endometriosis and adenomyosis or uterine tissue morcellation may be suggestive of EA. Histologic examination can give a definitive diagnosis and exclude malignant transformation.

Comparing magnetic resonance imaging and ultrasound in the clinical evaluation of fibroids prior to uterine artery embolization. Curr Probl Diagn Radiol 2024; 53:308-312.

Abstract
PURPOSE Uterine artery embolization has become established as a frontline treatment for uterine leiomyomata. In planning embolization, preprocedural imaging can further characterize pathology and anatomy, but it may also reveal coexisting diagnoses that have the potential to change clinical management. The purpose of this study is to compare the diagnostic outcomes of ultrasound and MRI performed for patients prior to undergoing embolization. METHODS The study cohort consisted of 199 patients who underwent uterine artery embolization at a single academic institution between 2013 and 2018. Prior to embolization, all patients had an MRI confirming a leiomyomata diagnosis. Additionally, 118 patients underwent transvaginal ultrasound within five years prior to MRI. MRI findings were analyzed and, when applicable, compared to prior ultrasound impressions to assess for the incidence of new findings. The diagnoses of interest were adenomyosis, hydrosalpinx, predominantly infarcted leiomyomata, and large intracavitary leiomyomata. Data were collected from retrospective chart review and included demographics, symptomology, and imaging reports. RESULTS 199 patients ultimately underwent embolization for treatment of MRI-confirmed leiomyomata. Of 118 patients who also had an ultrasound within five years prior to their MRI, 26 (22.0%) received a second gynecologic diagnosis based on MRI findings that was not previously seen on ultrasound. Of 81 patients who only had an MRI before embolization, 19 (23.5%) received a second gynecologic diagnosis not previously documented. The most common coexisting pathology was adenomyosis, presenting in 34 (17.1%) patients with leiomyomata, followed by large intracavitary leiomyomata (8, 4.0%), infarcted leiomyomata (7, 3.5%), and hydrosalpinx (6, 3.0%),. CONCLUSIONS When considering uterine artery embolization for the treatment of symptomatic leiomyomata, preprocedural MRI is superior to ultrasound in detecting coexisting pathologies, including adenomyosis and hydrosalpinx. It can also better characterize leiomyomata, including identifying lesions as intracavitary or infarcted. These findings have the potential to alter clinical management or contraindicate embolization entirely.

Abstract
OBJECTIVE To discuss the steps to performing and interpreting ultrasound imaging for pelvic pain in women with suspicions of endometriosis. DESIGN Educational video. SETTING Specialized gynecologic ultrasound clinic. PATIENTS Reproductive-age women with pelvic pain with findings suggestive of endometriosis. INTERVENTION Transvaginal ultrasound imaging. MAIN OUTCOME MEASURES A detailed discussion of findings suggesting endometriosis. RESULTS There are four basic sonographic steps for examining women with pelvic pain, especially when there is suspicion of endometriosis. Step 1: routine evaluation of the uterus and adnexa (this includes uterine orientation, sonographic signs of adenomyosis, and the presence or absence of endometrioma). Step 2: evaluation of transvaginal sonographic markers for endometriosis, for example, site-specific tenderness and ovarian mobility. Step 3: assessment of anterior and posterior compartments using a real-time ultrasound-based "sliding sign"; and Step 4: assessment for deep endometriotic nodules in anterior and posterior compartments. Note: the bladder should contain a small amount of urine for anterior compartment evaluation. CONCLUSIONS Ultrasound is a powerful and dynamic tool for evaluating pelvic pain with high sensitivity, specificity, and accuracy in diagnosing deep endometriosis. Ultrasound imaging is important not only for diagnosing but also to counsel patients properly, consent appropriately, and plan for interdisciplinary consultations.

[PMID: 38043844 DOI: 10.1016/j.fertnstert.2023.11.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 11/22/2023] [Accepted: 11/27/2023] [Indexed: 12/05/2023]
Abstract
OBJECTIVE To prospectively examine the association between adenomyosis type, location, and severity with reproductive outcomes in patients undergoing single embryo transfer (SET) with embryos derived from donor oocytes. DESIGN A prospective observational cohort study. SETTING University-affiliated in vitro fertilization center. PATIENTS Patients with infertility with (n = 114) and without (n = 114) adenomyosis who received their first donor oocyte transfer between January 2019 and January 2023 were included in this study. INTERVENTIONS Adenomyosis was confirmed with the presence of at least one direct feature visualized by 2- or 3-dimensional transvaginal ultrasound and classified according to type (diffuse or focal), localization (inner or outer myometrium and/or junctional zone [JZ]), and uterine extension (mild, moderate, or severe). After an artificial or natural endometrial preparation cycle, patients underwent SET in the blastocyst stage. MAIN OUTCOME MEASURES The primary outcome was the implantation rate. The secondary outcomes were the clinical pregnancy, live birth, and miscarriage rates after SET. RESULTS The presence of adenomyosis did not significantly affect the implantation, clinical pregnancy, or live birth rates. However, women with adenomyosis had a significantly higher miscarriage rate than those without adenomyosis (35.4% vs. 18.1%, respectively). The multivariate analysis assessed possible risk factors for each clinical outcome considered in the study and showed that adenomyosis affected the risk of miscarriage. Specifically, transvaginal sonography detection of adenomyosis in the JZ was associated with over threefold higher relative risk of miscarriage (relative risk [RR], 3.28; 95% confidence interval [CI], 1.38-7.78). Conversely, adenomyosis features detected exclusively in the outer myometrium were associated with a higher ongoing pregnancy rate (RR, 0.30; 95% CI, 0.13-0.72). Diffuse adenomyosis in the JZ and severe adenomyosis increased the relative risk of miscarriage two-fold (RR, 2.29; 95% CI, 1.22-4.30 and RR, 2.20; 95% CI, 1.19-4.04, respectively). CONCLUSIONS This study demonstrated that although adenomyosis did not significantly reduce the odds of implantation, the direct signs of adenomyosis in the JZ and disease severity are significant risk factors for miscarriage in patients receiving donor oocyte transfers. This study highlights the importance of thorough ultrasound examination and detailed adenomyosis classification in the assessment and management of patients with infertility.

Abstract
BACKGROUND The aim of this study was to evaluate the prevalence of ultrasound diagnosis of adenomyosis and endometriosis in young women complaining of pelvic pain and to find the symptoms and clinical characteristics associated with these diseases in young women. METHODS Cross-sectional study, including 100 young women (14-24 years) with a history of chronic pelvic pain. Women were asked detailed medical hystory and pain symptoms scores (Visual Analogue Scale) and underwent gynecological examination and ultrasound evaluation. RESULTS The prevalence of endometriosis and adenomyosis in young women amounted to 25.0% and 46.0%, respectively. A significant correlation was found between ovarian endometriosis and adenomyosis. Dysmenorrhea and dyspareunia were risk factors for adenomyosis. Dyschezia, dyspareunia, chronic pelvic pain, presence of sonographic soft markers suggestive of pelvic adhesions, being a worker and having a previous surgery were risk factors for endometriosis. Young women (20-24 years) had a higher incidence of both adenomyosis and endometriosis than adolescents (14-19 years). CONCLUSIONS Our outcomes strengthen the hypothesis of a progressive and common course of the natural history of endometriosis, which initially may manifest with symptoms, then with signs of pelvic adhesions and finally as adenomyosis, ovarian endometriomas or deep infiltrating endometriosis.

Abstract
BACKGROUND Adenomyosis is a benign disorder characterized by the presence of ectopic endometrial glands and stroma within the myometrium. The main clinical manifestations of adenomyosis are dysmenorrhea, menorrhagia, and infertility, which affect patients' quality of life. Recently, with advancements in imaging techniques, magnetic resonance imaging, and ultrasonography have become the main diagnostic tools for adenomyosis. In addition to the diagnosis and differential diagnosis of adenomyosis, ultrasonography can also be used to evaluate the severity of adenomyosis. The emergence of new techniques, such as elastography and contrast-enhanced ultrasonography (CEUS), has significantly improved the accuracy of ultrasound-based diagnosis of adenomyosis. These two imaging tools can also be used for the differential diagnosis of adenomyosis and the evaluation of treatment efficacy after medication or ablation procedure. OBJECTIVE we review the efficacy of ultrasonography as a diagnostic tool for adenomyosis. We also aim to introduce the potential of ultrasound imaging in the evaluation of the severity of this disease, as well as the application of elastography and contrast-enhanced ultrasonography (CEUS) in its diagnosis. RESULTS AND CONCLUSION Our findings reveal the potential value of ultrasonography combined with elastography and/or CEUS as medication guidance and efficacy evaluation tools in the long-term management of adenomyosis.

Adenomyosis and obstetric complications: A retrospective case-control study. Eur J Obstet Gynecol Reprod Biol 2024; 292:120-124. [PMID: 37992424 DOI: 10.1016/j.ejogrb.2023.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 11/09/2023] [Indexed: 11/24/2023]
Abstract
OBJECTIVE Adenomyosis is a uterine pathology affecting an increasing number of women of childbearing age. Its diagnosis is based upon histology or imaging [ultrasound or magnetic resonance imaging (MRI)]. Several studies have investigated the impact of adenomyosis on obstetric complications, with its diagnosis based on clinical symptoms, ultrasound or composite criteria. The aim of this study was to identify potential obstetric complications related to adenomyosis in women with an MRI-confirmed diagnosis. METHODS A single centre retrospective case-control study was undertaken in pregnant patients with an MRI-confirmed diagnosis of adenomyosis between January 2013 and December 2017 at the University Hospitals of Strasbourg. Controls were matched in a 4:1 ratio for age, parity and body mass index. Multivariate analysis was performed to identify obstetric complications. RESULTS In total, 291 women with an MRI-confirmed diagnosis of adenomyosis were identified during the study period. Of these, 89 patients achieved pregnancy after 24 weeks of gestation. The mean age of patients was 30.8 years. The adenomyosis group and the control group were comparable for matching criteria. Adenomyosis was found to be associated with increased risk of caesarean section [odds ratio (OR) 1.1, 95 % confidence interval (CI) 1.0-1.2; p = 0.03], intrauterine growth restriction (OR 1.3, 95 % CI 1.1-1.4; p < 0.001), postpartum haemorrhage (OR 1.2, 95 % CI 1.1- 1.4; p < 0.01), pre-eclampsia (OR 1.3, 95 % CI 1.0-1.6; p = 0.004) and previous spontaneous miscarriage (OR 2.09, 95 % CI 1.36-3.33; p < 0.001). Premature rupture of membranes, preterm delivery, severe intrauterine growth restriction and the risk of placenta praevia were not significantly higher in the adenomyosis group compared with the control group on multivariate analysis. CONCLUSION This study demonstrates increased risk of several obstetric complications (caesarean section, intrauterine growth restriction, postpartum haemorrhage, pre-eclampsia, history of spontaneous miscarriage) in women with adenomyosis. To the authors' knowledge, this is the first study to use MRI as the sole criterion for diagnosis. These results could be complemented by larger-scale prospective studies in order to manage these patients more effectively during pregnancy.

Adenomyosis in women undergoing hysterectomy for abnormal uterine bleeding associated with uterine leiomyomas. PLoS One 2023; 18:e0294925. [PMID: 38079406 PMCID: PMC10712893 DOI: 10.1371/journal.pone.0294925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Accepted: 11/10/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Uterine leiomyomas and adenomyosis are both common and often associated with abnormal uterine bleeding (AUB), including the symptom of heavy menstrual bleeding (HMB). Understanding the prevalence of adenomyosis in women with uterine leiomyomas could inform clinicians and patients in a way that may improve therapeutic approaches. OBJECTIVE To explore the prevalence of adenomyosis in a group of women who underwent hysterectomy for AUB-L, to determine the prevalence of submucous leiomyomas, and to examine the utility of preoperative ultrasound to detect the presence of adenomyosis. METHODS The Kaiser Permanente Hysterectomy Database (KPHD) was searched for women aged 18-52 undergoing hysterectomy for leiomyoma-associated chronic AUB (AUB-L) in 2018 and 2019. A target sample of 400 comprised those with at least 3 years in the Health System. Radiologists evaluated preoperative pelvic ultrasound images to determine leiomyoma size and level 2 FIGO type (submucous or other), and the linked electronic medical record abstracted for clinical features, including histopathological evidence of adenomyosis. RESULTS Of the 370 subjects that met the study criteria, adenomyosis was identified via histopathology in 170 (45.9%). There was no difference in the adenomyosis prevalence with (47.1%) and without (43.0%) at least one submucous leiomyoma. Subgroup analysis of ultrasound images by an expert radiologist for the presence of adenomyosis demonstrated a positive predictive value of 54.0% and a negative predictive value of 43.4%. CONCLUSIONS Adenomyosis was present in almost half of this AUB-L cohort undergoing hysterectomy and was equally prevalent in those with and without submucous leiomyomas as determined by sonographic evaluation. The imaging findings are in accord with prior investigators and demonstrate that 2-D ultrasound is insensitive to the presence of adenomyosis when the uterus is affected by leiomyomas. Further research is necessary to determine the impact of various adenomyosis phenotypes on the presence and severity of the symptom of HMB.

Abstract
Abnormal uterine bleeding (AUB) is defined by the International Federation of Gynecology and Obstetrics as bleeding from the uterine corpus that is abnormal in regularity, volume, frequency, or duration and occurs in the absence of pregnancy. AUB is a common condition that affects about a third of women in their lifetime. Abnormal bleeding in duration, quantity, or timing consists of 2 categories, predictable cyclical heavy menstrual bleeding (HMB) and irregular non-cyclical intermenstrual bleeding (IMB). The most common causes of HMB include fibroids and adenomyosis and IMB is commonly caused by ovulatory dysfunction such as in polycystic ovaries, endometrial polyp, or an IUD. A pelvic ultrasound is the initial and often only imaging modality needed in the imaging evaluation of abnormal uterine bleeding and can accurately identify the common causes of abnormal uterine bleeding in the reproductive age group.

Differences in the incidence of obstetric complications depending on the extent and location of adenomyosis lesions. J Matern Fetal Neonatal Med 2023; 36:2226789. [PMID: 37787637 DOI: 10.1080/14767058.2023.2226789] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 10/31/2022] [Accepted: 03/08/2023] [Indexed: 10/04/2023]
Abstract
OBJECTIVES Although adenomyosis is reportedly associated with adverse pregnancy outcomes, clinical factors related to the high risk of obstetric complications are unclear. This study aimed to elucidate the characteristics of adenomyosis lesions associated with the increased incidence of obstetric complications based on imaging findings. METHODS This was a retrospective, observational cohort study conducted in a tertiary perinatal care center. Eighty-eight singleton pregnant women with adenomyosis were included in the study. Based on magnetic resonance imaging or ultrasonography before and/or during pregnancy, patients were classified according to three types of image characteristics: the extent of adenomyosis lesion (focal type or diffuse type), location of the lesion (extrinsic type, intrinsic type, or indeterminate type), the positional relationship between the lesion and the placenta (placenta distant from adenomyosis or placenta over adenomyosis), and the incidence of obstetric complications were examined. RESULTS Patients with diffuse type adenomyosis are significantly more likely to have spontaneous second-trimester miscarriage (diffuse type vs. focal type: 16.7 vs. 0%, p < .01), preterm premature rupture of membranes (19.4 vs. 1.9%, p < .01), and preeclampsia (25.0 vs. 7.7%, p = .02), as compared to those with focal type adenomyosis. In a comparison of the three location types, the incidence of placental malposition was higher in patients with the extrinsic type adenomyosis (extrinsic type vs. intrinsic type vs. indeterminate type: 20.0 vs. 6.7 vs. 2.3%, p = .03). Comparisons between the types of the placenta over or distant from adenomyosis lesion displayed no significant differences in the frequencies of obstetric complications. CONCLUSIONS We demonstrated that the frequency of obstetric complications related to adenomyosis varies depending on the extent and location of the lesion; patients with diffuse type adenomyosis have an increased risk of spontaneous second-trimester miscarriage, preterm premature rupture of membranes, and preeclampsia, while patients with extrinsic type adenomyosis have an increased risk of placental malposition. Imaging evaluation of adenomyosis prior to conception or early in pregnancy may be useful for the obstetrical risk assessment among patients with adenomyosis.

Accuracy of ultrasound signs on two-dimensional transvaginal ultrasound in prediction of adenomyosis: prospective multicenter study. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2023; 62:739-746. [PMID: 36920431 DOI: 10.1002/uog.26197] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Revised: 01/09/2023] [Accepted: 02/27/2023] [Indexed: 06/18/2023]
Abstract
OBJECTIVE Two-dimensional (2D) transvaginal ultrasound (TVS) is an accessible and cost-effective diagnostic tool for the detection of adenomyosis. Different ultrasound features related to adenomyosis have been described, but the predictive value of each ultrasound sign and their combinations requires further investigation. We aimed to analyze the accuracy of 2D-TVS and describe possible combinations of ultrasound signs with a high predictive value in the diagnosis of adenomyosis. METHODS This was a prospective multicenter study of patients scheduled for laparoscopic hysterectomy who had been examined using standardized 2D-TVS at nine expert centers specializing in the diagnosis and treatment of endometriosis. 2D-TVS examination included nine typical adenomyosis ultrasound features, comprising heterogeneous myometrium, myometrial linear striations, myometrial cysts, subendometrial microcysts, asymmetrical myometrial thickening, uterine enlargement, the 'question mark sign', thickening of the junctional zone and hyperechoic myometrial spots, in order to predict or exclude the presence of adenomyosis. Ultrasound examination results were compared with histology after hysterectomy. The diagnostic reliability of the nine ultrasound signs and their combinations, and the influence of concurrent fibroids on the accuracy of the results, were analyzed. RESULTS A total of 202 patients were enrolled into the study. Histopathological examination revealed adenomyosis in 130 patients (64.4%). The accuracy of prediction of adenomyosis by 2D-TVS examination using all signs was 63.4% (positive predictive value, 71.5%; negative predictive value, 48.6%; sensitivity, 71.5%; specificity, 48.6%). Heterogeneous myometrium, myometrial cysts, subendometrial microcysts and hyperechoic myometrial spots showed the highest accuracy (55.7-62.1%) as individual ultrasound signs for the prediction of adenomyosis. The combination of the most accurate ultrasound signs (subendometrial microcysts, myometrial cysts and heterogeneous myometrium) improved the specificity of prediction (86.1%) when compared with that of these three single markers (35.2-81.7%). Uterine enlargement and asymmetry showed both low sensitivity (60.8% and 52.3%, respectively) and specificity (41.7% and 49.3%, respectively) as individual sonographic signs. CONCLUSIONS Heterogeneous myometrium, myometrial cysts, subendometrial microcysts and hyperechoic myometrial spots showed the highest accuracy for the detection of adenomyosis in this study, while uterine enlargement and asymmetry led to high false-positive and false-negative results. A combination of ultrasound features including the most accurate signs increases specificity. © 2023 The Authors.

Abstract
BACKGROUND To determine whether there is a correlation between stiffness measured by strain elastography and the severity of dysmenorrhea and to determine the value of elastography in evaluating severe dysmenorrhea in patients with adenomyosis. METHODS The correlation between tissue stiffness and dysmenorrhea was analyzed by performing elastography on premenopausal women diagnosed with adenomyosis. Expression levels of transforming growth factor-β (TGF-β), α-smooth muscle actin (α-SMA), and protein gene product 9.5 (PGP9.5) were detected by immunohistochemistry; the correlation of TGF-β and α-SMA levels with the tissue stiffness and the degree of fibrosis was further analyzed. Also, the relationship of the PGP9.5 expression level with the tissue stiffness and degree of dysmenorrhea was determined. RESULTS The degree of dysmenorrhea was significantly positively correlated with lesion stiffness in patients with adenomyosis but not with the uterine or lesion volume. The cutoff for the strain ratio was > 1.36 between the adenomyosis and control groups, with an area under the curve (AUC) of 0.987. For severe dysmenorrhea, the cutoff for the strain ratio was > 1.65 in patients with adenomyosis, with an AUC of 0.849. TGF-β, α-SMA, and PGP9.5 expression levels were higher in adenomyotic lesions than in the endometrium of the adenomyosis and control groups. Both TGF-β and α-SMA levels were positively correlated with the tissue stiffness and degree of fibrosis. Additionally, the expression level of PGP9.5 showed a positive correlation with the tissue stiffness and degree of dysmenorrhea. CONCLUSIONS Elastography can be used to evaluate the degree of dysmenorrhea; the greater the tissue stiffness, the greater the degree of dysmenorrhea. In addition, elastography performed well in the diagnosis of adenomyosis and the evaluation of severe dysmenorrhea in patients with adenomyosis.

Abstract
OBJECTIVE To evaluate the accuracy of transvaginal ultrasound in the diagnosis of adenomyosis using MRI as the gold standard, and to characterise the most commonly seen and accurate ultrasonographic features and their combination. STUDY DESIGN Cross-sectional, descriptive study. Place and Duration of the Study: Department of Radiology, The Aga Khan University Hospital, Karachi, from January 2018 to July 2021. METHODOLOGY Transvaginal ultrasound examination was performed on patients (n = 208) who presented with symptoms related to menstrual cycles and pelvic abnormalities. Additionally, patients who sought infertility evaluation were also included in the study. The findings from the ultrasound examinations were assessed and tabulated alongside the results of the MRI scans. All examinations were conducted by senior radiologists / sonographers. The sensitivity, specificity, positive and negative predictive values (PPV and NPV, respectively) of ultrasound features were calculated individually and in combination, taking MRI as the gold standard. To enhance the accuracy of ultrasound findings, various variables were combined, and their sensitivities and specificities were calculated. RESULTS Overall, transvaginal ultrasound had a high specificity of 96.15% (95% CI: 85.67 - 99.33), a relatively low sensitivity of 74.36% (95% CI: 66.63 - 80.85), PPV of 98.31 (95% CI: 93.40 - 99.70) and NPV of 55.56 (95% CI: 44.73 - 65.90). The most sensitive dual variable used was a bulky uterus combined with altered myometrial echotexture, with a sensitivity of 72.97% (95% CI: 64.95 - 79.78) and specificity of 95.83% (95% CI: 84.57-99.27). The best combined triple variable was a bulky uterus with altered echotexture and streaky myometrium, with a sensitivity of 71.85% (95% CI: 63.35 - 79.10) and a specificity of 95.46% (95% CI: 83.30 - 99.21). CONCLUSION Transvaginal ultrasound features can identify adenomyosis characteristics in most of the patients. This could reduce the number of pelvic MRIs performed for the detection of adenomyosis.

Abstract
OBJECTIVE To investigate the factors affecting the efficacy of ultrasound (US)-guided percutaneous microwave ablation (PMWA) for adenomyosis with abnormal uterine bleeding (AUB-A). METHODS Baseline data of patients with AUB-A who underwent US-guided PMWA treatment between October 2020 and October 2021, including demography characteristics, laboratory and imaging examination results were retrospectively analyzed. 3D reconstruction of magnetic resonance imaging (MRI) was applied to quantitatively assess the local treatment responses, including ratio of non-perfusion volume to adenomyosis volume (NPVr), ablation rate of the endometrial-myometrial junction (EMJ), and surface area (SA) of the ablated part of the EMJ. Patients were followed up at 3, 6, and 12 months after treatment, and divided into two groups: group with complete relief (CR), and group with partial relief (PR) or no relief (NR). Data were compared between them. RESULTS Thirty-one patients were analyzed with a mean age of 38.7 ± 6.8 years (range: 24-48): 48.4% (15/31), 63.3% (19/30), and 65.5% (19/29) achieved CR at 3, 6, and 12 months, respectively. In univariate analysis, compared with the PR/NR group, serum CA125 levels were significantly lower in CR group at 3 months, while ablation rates of EMJ and SA of the ablated part of the EMJ were significantly higher at the three time points. Other baseline characteristics and NPVr did not differ between the two groups. CONCLUSION Baseline CA125 and ablation rate of the EMJ and SA of the ablated part of the EMJ are associated with the outcome of AUB-A patients after US-guided PMWA treatment.

Abstract
The purpose of this study was to implore the association among clinical features, long-term fertility outcomes and the anatomical location of adenomyosis identified by ultrasound. We collected data of non-pregnant patients between 20 and 40 years old who had undergone surgical exploration for benign gynecological conditions at our institution between January 2010 and December 2017. A total of 158 women met the inclusion criteria and were allocated into three groups according to the ultrasound-determined adenomyosis anatomical location: anterior (Group A), posterior (Group B), both posterior and anterior (Group C). 44.3% (70/158) adenomyosis was located at the posterior side. History of miscarriage and parity were significantly higher in Group C (p = 0.036 and 0.001 respectively). Group C also had a higher concurrence rate of ovarian endometrioma (OEM) (80.4%, p = 0.002), pelvic adhesion (80.4%, P = 0.003) and the revised American Fertility Society (rAFS) Score (median64, range2-100, P < 0.001), while a significantly lower rate of concurrent peritoneal endometriosis (P = 0.01). Group B showed a relative higher rate of coexistent heavy menstrual bleeding (28.6%, p = 0.04) and oviduct obstruction (24.3%, P = 0.038). Group A had a higher proportion of coexistent leiomyoma (53.1%, P = 0.002). There were no significant differences between group A, B, and C in terms of pain symptoms, endometrial polyps, operation time, and endometriosis fertility index score and other basic characters (p > 0.05). During the follow-up, 59.2% (61/103) patients had clinical pregnancies, and 26.2% (16/61) of them experienced pregnancy loss. Total in vitro fertilization and embryo transfer pregnancy rate was 64.6% (42/65) and spontaneous pregnancy rate was 50.0% (19/38). The Kaplan-Meier curves demonstrated significant lower cumulative pregnancy rate in Group C than Group A and Group B (p = 0.01). Severe obstetric complications such as placenta previa, placenta accreta, preeclampsia, and preterm birth were only found in women with adenomyosis located in the posterior side. In conclusion, types of adenomyosis based on sonographic location had different clinical features and pregnancy outcome. Patients with adenomyosis lesion in both anterior and posterior sides had higher combination of OEM, pelvic adhesion and rAFS score.

Pregnancy is associated with reduced progression of symptomatic adenomyosis: a retrospective pilot study. BMC Pregnancy Childbirth 2023; 23:634. [PMID: 37667168 PMCID: PMC10476322 DOI: 10.1186/s12884-023-05956-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Accepted: 08/26/2023] [Indexed: 09/06/2023] Open
Abstract
BACKGROUND Adenomyosis is a common gynecological disease in women of reproductive age and causes various symptoms such as dysmenorrhea and heavy menstrual bleeding. However, the influence of pregnancy on the progression of adenomyosis remains unclear. The insight into whether the size of adenomyosis is increased, decreased, or unchanged during pregnancy is also undetermined. The current study aimed to evaluate the influence of pregnancy in patients with symptomatic adenomyosis. METHODS This study retrospectively enrolled patients diagnosed with adenomyosis by magnetic resonance imaging between 2015 and 2022 at The University of Tokyo Hospital. Uterine size changes were evaluated by two imaging examinations. In the pregnancy group, the patients did not receive any hormonal and surgical treatments, except cesarean section, but experienced pregnancy and delivery between the first and second imaging examinations. In the control group (nonpregnancy group), the patients experienced neither hormonal and surgical treatments nor pregnancy from at least 1 year before the first imaging to the second imaging. The enlargement rate of the uterine size per year (percentage) was calculated by the uterine volume changes (cm3) divided by the interval (years) between two imaging examinations. The enlargement rate of the uterine size per year was compared between the pregnancy group and the control group. RESULTS Thirteen and 11 patients with symptomatic adenomyosis were included in the pregnancy group and in the control group, respectively. The pregnancy group had a lower enlargement rate per year than the control group (mean ± SE: -7.4% ± 3.6% vs. 48.0% ± 18.5%, P < 0.001), indicating that the size of the uterus with adenomyosis did not change in the pregnancy group. CONCLUSIONS Pregnancy is associated with reduced progression of symptomatic adenomyosis.

Adenomyosis at a Glance: An Integrated Review of Transvaginal Ultrasound and MR Imaging Findings. Curr Probl Diagn Radiol 2023; 52:412-417. [PMID: 37230885 DOI: 10.1067/j.cpradiol.2023.05.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 03/20/2023] [Accepted: 05/08/2023] [Indexed: 05/27/2023]
Abstract
Adenomyosis is a benign uterine disorder increasingly recognized in premenopausal women. Given its significant clinical burden, an accurate noninvasive diagnosis is paramount. Both transvaginal ultrasound (TVUS) and magnetic resonance (MR) provide an adequate assessment of adenomyosis, the former being recommended for first-line imaging evaluation and the latter being mainly used as a problem-solving technique. In this article, the authors review the TVUS and MR imaging findings of adenomyosis while referring to their histopathological background. Whereas direct signs correlate directly to ectopic endometrial tissue and are highly specific to adenomyosis, indirect signs result from myometrial hypertrophy and increase diagnostic sensitivity. Potential pitfalls, differential diagnoses, and frequently associated estrogen-dependent conditions are also discussed.

Magnetic Resonance Imaging-guided Focused Ultrasound Surgery in a Swine Adenomyosis Model. Acad Radiol 2023; 30 Suppl 2:S220-S226. [PMID: 36624022 DOI: 10.1016/j.acra.2022.11.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 11/15/2022] [Accepted: 11/30/2022] [Indexed: 01/09/2023]
Abstract
RATIONALE AND OBJECTIVES The purpose of this study was to explore the feasibility of magnetic resonance imaging-guided focused ultrasound surgery (MRgFUS) for the treatment of an adenomyosis model of Bama pigs and the changes in the level of oxytocin receptor (OTR), vascular endothelial growth factor (VEGF), and cyclooxygenase-2 (COX-2) in the myometrium tissues of Bama pigs after MRgFUS. MATERIALS AND METHODS Three Bama pig models of adenomyosis were established by autologous endometrial implantation and evaluated by magnetic resonance imaging, computed tomography, and hematoxylin-eosin (H&E) staining. After the successful construction of the model, the pigs underwent MRgFUS. Before the modeling surgery, three months after the modeling, and two months after ablation, the myometrium tissues were clipped, then embedded and H&E stained for immunohistochemical examination. The average optical density of OTR, VEGF, and COX-2 were semi-quantitatively analyzed. RESULTS The adenomyosis models were established in all Bama pigs and confirmed by magnetic resonance imaging, computed tomography and H&E staining. Magnetic resonance imaging and computed tomography examination showed that the uterine wall at the modeling site was significantly thickened with uneven enhancement after contrast injection. All Bama pigs with adenomyosis lesions underwent MRgFUS without complications. The expression level of OTR and COX-2 in the myometrium increased three months after modeling surgery and decreased two months after MRgFUS. The expression level of VEGF decreased two months after MRgFUS. CONCLUSION Autologous endometrial implantation is effective in establishing the adenomyosis model of Bama pigs. It is feasible to treat adenomyosis in the Bama pig model with MRgFUS. The levels of OTR, COX-2 and VEGF in the local myometrium decreased after MRgFUS, which may be associated with symptom relief after treatment.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2023; 62:23-41. [PMID: 36647238 DOI: 10.1002/uog.26159] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 12/15/2022] [Accepted: 12/23/2022] [Indexed: 06/17/2023]
Abstract
OBJECTIVE To determine the prevalence of adenomyosis in women with subfertility. METHODS A systematic search was conducted in MEDLINE, EMBASE, CINAHL Plus, Google Scholar, PsycINFO and Web of Science Core Collection from database inception to October 2022. The included studies evaluated the prevalence of adenomyosis in women with subfertility, with or without endometriosis and/or uterine fibroids. Secondary analyses were conducted to identify variation in the prevalence of isolated adenomyosis according to geographical location, diagnostic modality, diagnostic criteria, type of ultrasound, ultrasound features of adenomyosis and the use of assisted reproductive technology. RESULTS Among 21 longitudinal studies evaluating 25 600 women, the overall pooled prevalence of isolated adenomyosis was 10% (95% CI, 6-15%) (I2 = 99.1%; tau2 = 0.12). The pooled prevalence was 1% (95% CI, 0-4%) for adenomyosis with concurrent fibroids (eight studies; I2 = 95.8%; tau2 = 0.03), 6% (95% CI, 3-11%) for adenomyosis with concurrent endometriosis (18 studies; I2 = 98.6%; tau2 = 0.12) and 7% (95% CI, 2-13%) for adenomyosis with concurrent endometriosis and/or fibroids (nine studies; I2 = 98.3%; tau2 = 0.09). The prevalence of isolated adenomyosis varied substantially according to geographical location, with Australia exhibiting the highest pooled prevalence of adenomyosis (19% (95% CI, 12-27%)), which was significantly higher compared with that in Asia (5% (95% CI, 1-12%)). The pooled prevalence of isolated adenomyosis diagnosed using a combination of direct and indirect ultrasound features was 11% (95% CI, 7-16%), whereas it was 0.45% (95% CI, 0-1%) in the study in which only an indirect feature was used as the diagnostic criterion. CONCLUSION One in 10 women with subfertility have a diagnosis of isolated adenomyosis. The prevalence of adenomyosis varies according to the presence of concurrent endometriosis and/or fibroids. © 2023 The Authors.

Abstract
INTRODUCTION Adenomyosis prevalence among women with infertility is increasing; their management during in vitro fertilization is usually based on ultrasound diagnosis alone. Herein, we summarize the latest evidence on the impact of ultrasound-diagnosed adenomyosis on in vitro fertilization outcomes. MATERIAL AND METHODS The study was registered with The International Prospective Register of Systematic Reviews (CRD42022355584). We searched PubMed, Embase, and Cochrane Library databases from inception to January 31, 2023, for cohort studies on the impact of adenomyosis on in vitro fertilization outcomes. Fertility outcomes were compared according to the presence of adenomyosis as diagnosed by ultrasound, concurrent endometriosis and adenomyosis, and MRI-based or MRI- and ultrasound-based adenomyosis diagnosis. Live birth rate was the primary outcome while clinical pregnancy and miscarriage rates were secondary outcomes. RESULTS Women diagnosed with adenomyosis by ultrasound had lower live birth (odds ratio [OR] = 0.66; 95% confidence interval [CI]: 0.53-0.82, grade: very low), lower clinical pregnancy (OR = 0.64; 95% CI: 0.53-0.77, grade: very low), and higher miscarriage (OR = 1.81; 95% CI: 1.35-2.44, grade: very low) rates than those without adenomyosis. Notably, symptomatic and diffuse, but not asymptomatic adenomyosis as diagnosed by ultrasound, adversely affected in vitro fertilization outcomes, with lower live birth (OR = 0.57; 95% CI: 0.34-0.96, grade: very low), clinical pregnancy (OR = 0.69; 95% CI: 0.57-0.85, grade: low), and miscarriage (OR = 2.48, 95% CI: 1.28-4.82, grade: low) rates; and lower live birth (OR = 0.37; 95% CI: 0.23-0.59, grade: low) and clinical pregnancy (OR = 0.50; 95% CI: 0.34-0.75, grade: low), but not miscarriage rate (OR = 2.18; 95% CI: 0.72-6.62, grade: very low), respectively. Concurrent adenomyosis in endometriosis is associated with a significantly lower live birth rate (OR = 0.44; 95% CI: 0.26-0.75, grade: low) than endometriosis alone. Finally, the use of MRI-based or MRI- and ultrasound-based adenomyosis diagnosis showed no significant association with in vitro fertilization outcomes (grade: very low for all outcomes). CONCLUSIONS Considering ultrasound findings, symptoms, and different subtypes of adenomyosis may aid in offering personalized counseling, improving treatment decisions, and achieving better outcomes of in vitro fertilization.

Abstract
PURPOSE Adenomyosis is a common disease of females during their reproductive age. As of today, histologic examination of the uterus after hysterectomy constitutes the gold standard for diagnosis. The aim of this study was to determine the validity of sonographic, hysteroscopic, and laparoscopic criteria for the diagnosis of the disease. METHODS This study included data collected from 50 women in the reproductive age of 18-45 years, who underwent a laparoscopic hysterectomy in the gynecology department of the Saarland University Hospital in Homburg between 2017 and 2018. The patients with adenomyosis were compared with a healthy control group. RESULTS We collected data of anamnesis, sonographic criteria, hysteroscopic criteria and laparoscopic criteria and compared it with the postoperative histological results. A total 25 patients were diagnosed with adenomyosis postoperatively. For each of these; at least three sonographic diagnostical criteria for adenomyosis were found compared with a maximum of two for the control group. CONCLUSION This study demonstrated an association between pre- and intraoperative signs of adenomyosis. In this way, it shows a high diagnostic accuracy of the sonographic examination as a pre-operative diagnostic method of the adenomyosis.

Ultrasound Elastography for the Diagnosis of Endometriosis and Adenomyosis: A Systematic Review with Meta-analysis. ULTRASOUND IN MEDICINE & BIOLOGY 2023; 49:699-709. [PMID: 36528440 DOI: 10.1016/j.ultrasmedbio.2022.11.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 10/05/2022] [Accepted: 11/10/2022] [Indexed: 06/17/2023]
Abstract
Elastography is capable of measuring tissue mechanical properties and elasticity. It is used to help diagnose various diseases, although its use in pelvic endometriosis remains to be established. A systematic review and meta-analysis were conducted to assess transvaginal ultrasound elastography for the diagnosis of different manifestations of endometriosis and adenomyosis. PRISMA guidelines were used for a Medline, PubMed, Embase, BVS/Bireme, Scopus, Cochrane Library and Escudos database search. Studies indexed until March 2021 that evaluated elastography compared with histopathological results (gold standard), ultrasound or magnetic resonance imaging for diagnosis of pelvic endometriosis and adenomyosis were eligible. The Rayyan platform was used to select studies. Sensitivity (S), specificity (Ps), positive and negative predictive values and receiver operating characteristic curves were calculated for elastographic diagnosis of endometriosis. A meta-analysis using Review Manager 5 and Open Meta Analyst was performed. Bias risk in the studies was analyzed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool. This systematic review was prospectively registered in the PROSPERO database: CRD42021244555. Among the 163 identified citations, 10 studies were eligible for review (5 for diagnosis of adenomyosis, 2 for endometrioma, 3 for deep intestinal endometriosis and rectovaginal septum [deep pelvic endometriosis], N = 744 women). In deep pelvic endometriosis, lesions diagnosed by elastography were found to correlate with histopathology results. Increased "stiffness" (elastography) was associated with a higher fibrotic component, with S = 78%-100% and Ps = 100%, according to the authors. On elastography, endometriomas were stiffer than hemorrhagic cysts (S = 82%, Ps = 79%) and malignant tumors (S = 86%, Ps = 100%). For these lesions, a meta-analysis could not be performed because the small number of studies and insufficient data. In adenomyosis, meta-analysis and receiver operating characteristic curve analysis revealed that elastography had good sensitivity and specificity. Studies indicated a low bias risk by QUADAS-2. Elastography had high sensitivity and specificity for deep pelvic endometriosis diagnosis, and its findings correlated with histopathology results. For adenomyosis, the meta-analysis confirmed the sensitivity and specificity results of the studies. Given these results, elastography may be a promising imaging test, contributing to non-invasive diagnosis of endometriosis and adenomyosis.

Abstract
BACKGROUND This study aims to evaluate the diagnostic performance of Deep Learning (DL) machine for the detection of adenomyosis on uterine ultrasonographic images and compare it to intermediate ultrasound skilled trainees. METHODS Prospective observational study were conducted between 1 and 30 April 2022. Transvaginal ultrasound (TVUS) diagnosis of adenomyosis was investigated by an experienced sonographer on 100 fertile-age patients. Videoclips of the uterine corpus were recorded and sequential ultrasound images were extracted. Intermediate ultrasound-skilled trainees and DL machine were asked to make a diagnosis reviewing uterine images. We evaluated and compared the accuracy, sensitivity, positive predictive value, F1-score, specificity and negative predictive value of the DL model and the trainees for adenomyosis diagnosis. RESULTS Accuracy of DL and intermediate ultrasound-skilled trainees for the diagnosis of adenomyosis were 0.51 (95% CI, 0.48-0.54) and 0.70 (95% CI, 0.60-0.79), respectively. Sensitivity, specificity and F1-score of DL were 0.43 (95% CI, 0.38-0.48), 0.82 (95% CI, 0.79-0.85) and 0.46 (0.42-0.50), respectively, whereas intermediate ultrasound-skilled trainees had sensitivity of 0.72 (95% CI, 0.52-0.86), specificity of 0.69 (95% CI, 0.58-0.79) and F1-score of 0.55 (95% CI, 0.43-0.66). CONCLUSIONS In this preliminary study DL model showed a lower accuracy but a higher specificity in diagnosing adenomyosis on ultrasonographic images compared to intermediate-skilled trainees.

Transvaginal ultrasound- and laparoscopy-guided percutaneous microwave ablation for adenomyosis has short- and long-term benefits: a single-center study. Int J Hyperthermia 2023; 40:2233713. [PMID: 37460100 DOI: 10.1080/02656736.2023.2233713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 06/30/2023] [Accepted: 07/02/2023] [Indexed: 07/20/2023] Open
Abstract
OBJECTIVES Transvaginal ultrasound- and laparoscopy-guided percutaneous microwave ablation (TLPMA) is a minimally invasive alternative technique with low risk, fast recovery and few side effects. We aimed to evaluate the safety and long-term efficacy of TLPMA for treating adenomyosis. METHODS We included 79 patients with symptomatic adenomyosis who underwent TLPMA and 44 patients with adenomyosis who received the levonorgestrel-releasing intrauterine system (LNG-IUS). We evaluated the role of laparoscopy in TLPMA as well as the short- and long-term effects of TLPMA. RESULTS The mean age of the 79 patients who underwent TLPMA was 41.8 years. There was no difference in the mean age between the TLPMA and LNG-IUS groups. Laparoscopy could help to separate pelvic adhesions, provide a wide antenna path, and observe the uterine surface and bowel movement. No major complications were found in patients who underwent TLPMA. There was a significant post-treatment reduction in both the uterine and lesion volumes (p < 0.001). After a median follow-up duration of 36 months (range: 1-60 months), the uterine and lesion volumes remained stable. Additionally, most patients remained without dysmenorrhea, which confirms the long-term efficacy of TLPMA. CONCLUSIONS TLPMA is a feasible, minimally invasive technique for the treatment of adenomyosis, which significantly decreases the uterine and lesion volumes and has a good long-term effect.

Abstract
RATIONALE Intramural ectopic pregnancy (IMP) is a rare ectopic pregnancy with an unclear etiology, and standard treatment guidelines currently remain unclear. The main treatment option is local excision of IMP via laparoscopy or laparotomy. PATIENT CONCERNS A 32-year-old woman with adenomyosis presented with amenorrhea for 7 weeks and a serum β-human chorionic gonadotropin (HCG) level of 6882 IU/L. The patient had a history of laparotomy for adenomyosis 5 years previously. Three-dimensional ultrasonography showed a live gestational sac (GS) of 9 × 15 × 18 mm located in the left posterior wall of the uterus and a sinus tract connecting the sac and the endometrial cavity. MRI revealed the GS located in the adenomyosis and a 1.0-cm sinus tract connecting the GS and the endometrial cavity. DIAGNOSES IMP with adenomyosis. INTERVENTIONS High-intensity focused ultrasound (HIFU) treatment combined with systemic methotrexate (MTX) was performed to treat IMP, which would avoid operation and massive bleeding. OUTCOMES Serum β-HCG levels decreased to normal 4 weeks after HIFU treatment and the GS was not found on MRI after 4 months. The sinus tract was significantly shortened after the HIFU treatment. LESSONS HIFU ablation combined with systemic MTX is effective for the treatment of IMP and is favorable for maintaining fertility.

Abstract
OBJECTIVES To assess the changes of blood flow in adenomyosis (AM) after higher-dose oxytocin (OT) in different doses, and to evaluate the safety for patients. METHODS A total of 124 patients with AM were randomly divided into 4 groups with continuous intravenous infusion of OT as 0.06, 0.12, 0.24 and 0.36 U/min, respectively. The changes of arteries of AM before and after intravenous infusion of OT were observed by color Doppler ultrasound. The changes of blood flow volume of the artery of AM before and after intravenous infusion of OT were compared among the 4 groups, and the vital signs and adverse drug reactions were monitored during intravenous drip. RESULTS During the trial, no severe adverse reactions occurred and the vital signs of all the patients were stable. Among the 4 groups, it was found that there was a significant difference in the change of blood flow volume of blood artery in AM lesions between 0.06 U/min OT group and the other three groups after intravenous drip of OT (P < .05), but there was no significant difference in blood flow volume among the three groups (P > .05), and the difference of adverse drug reactions was statistically significant with the increase of OT dose (P < .05). CONCLUSION OT can effectively reduce the blood flow volume of AM lesions, and continuous intravenous infusion of 0.12 U/min OT is an appropriate dose that can not only minimize the blood flow volume but also reduce the incidence of adverse drug reactions.

Abstract
OBJECTIVE To equip reproductive surgeons with an approach to the Osada procedure and critical prophylactic hemostatic measures that optimize perioperative outcomes. DESIGN Stepwise demonstration of the Osada procedure with narrated video footage. SETTING Definitive management of symptomatic adenomyosis requires hysterectomy. However, adenomyomectomy can improve symptoms and restore anatomy while maintaining fertility potential. Limited but comparable perioperative outcomes exist for minimally invasive methods of adenomyomectomy, and most involve resection of focal, not diffuse, adenomyosis. Among the literature involving resection of diffuse adenomyosis using minimally invasive methods, relatively small volumes of resected tissue are reported and none include obstetric outcomes. Most published reports for excision of diffuse adenomyosis involve laparotomic resection, likely because of specific intraoperative challenges curtailed by this approach. In response, a laparoscopic-assisted laparotomic approach was developed in 2011 by Dr. Hisao Osada, a reproductive surgeon in Japan. This procedure involves aggressive excision of adenomyotic tissue with prophylactic hemostatic techniques and subsequent uterine wall reconstruction using a triple-flap method. Compared with other excisional methods for diffuse adenomyomectomy, the Osada procedure has the best reported obstetric outcomes. PATIENT(S) A 37-year-old nulliparous female presented with pelvic pain, bulk symptoms, abnormal uterine bleeding, and infertility. Physical examination demonstrated a 20-week, bulky uterus with limited bimanual mobility. Her endometrial cavity was inaccessible because of marked anatomic distortion. Magnetic resonance imaging revealed marked abnormality of her endometrial contour because of a 15 cm adenomyoma with diffuse adenomyomatous tissue in the posterior uterine compartment. Prior interventions included a trial of combined hormonal contraceptive, leuprolide acetate, and tranexamic acid. She was interested in fertility-sparing adenomyomectomy to address symptoms and fertility potential and chose to proceed with the Osada procedure. She was optimized medically with oral and parenteral iron therapy to bring her hemoglobin from 55-111 g/L preoperatively. Institutional review board approval and informed consent from the patient were obtained. INTERVENTION(S) The Osada procedure was performed using the following 8 surgical steps: Systemic administration of tranexamic acid was also administered intraoperatively. MAIN OUTCOME MEASURE(S) Perioperative blood loss, anatomic normalization, symptom remediation, and maintenance of fertility potential. RESULTS Perioperative blood loss was minimal, 469 g of adenomyotic tissue was extracted, and discharge was on postoperative day 2 without any complications. Three months later, cyclic pain and bleeding had improved markedly, ultrasound confirmed Doppler flow throughout the uterus, hysterosalpingogram demonstrated a nonobliterated endometrial cavity and tubal patency, and magnetic resonance imaging confirmed normalized uterine dimensions measuring 11 × 7 cm from 19 × 10 cm. Most literature supports waiting at least 6-12 months and until demonstration of normalized uterine blood flow in the operated area before attempting conception. CONCLUSION Fertility-sparing excision of diffuse adenomyosis can be achieved safely using the Osada procedure, following the 8 discrete steps demonstrated in this video. Reproductive surgeons can reference this video to teach and maintain this important procedure.

Consensus on revised definitions of Morphological Uterus Sonographic Assessment (MUSA) features of adenomyosis: results of modified Delphi procedure. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2022; 60:118-131. [PMID: 34587658 PMCID: PMC9328356 DOI: 10.1002/uog.24786] [Citation(s) in RCA: 64] [Impact Index Per Article: 32.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Revised: 08/18/2021] [Accepted: 09/16/2021] [Indexed: 05/13/2023]
Abstract
OBJECTIVES To evaluate whether the Morphological Uterus Sonographic Assessment (MUSA) features of adenomyosis need to be better defined and, if deemed necessary, to reach consensus on the updated definitions. METHODS A modified Delphi procedure was performed among European gynecologists with expertise in ultrasound diagnosis of adenomyosis. To identify MUSA features that might need revision, 15 two-dimensional (2D) video recordings (four recordings also included three-dimensional (3D) still images) of transvaginal ultrasound (TVS) examinations of the uterus were presented in the first Delphi round (online questionnaire). Experts were asked to confirm or refute the presence of each of the nine MUSA features of adenomyosis (described in the original MUSA consensus statement) in each of the 15 videoclips and to provide comments. In the second Delphi round (online questionnaire), the results of the first round and suggestions for revision of MUSA features were shared with the experts before they were asked to assess a new set of 2D and 3D still images of TVS examinations and to provide feedback on the proposed revisions. A third Delphi round (virtual group meeting) was conducted to discuss and reach final consensus on revised definitions of MUSA features. Consensus was predefined as at least 66.7% agreement between experts. RESULTS Of 18 invited experts, 16 agreed to participate in the Delphi procedure. Eleven experts completed and four experts partly finished the first round. The experts identified a need for more detailed definitions of some MUSA features. They recommended use of 3D ultrasound to optimize visualization of the junctional zone. Fifteen experts participated in the second round and reached consensus on the presence or absence of ultrasound features of adenomyosis in most of the still images. Consensus was reached for all revised definitions except those for subendometrial lines and buds and interrupted junctional zone. Thirteen experts joined the online meeting, in which they discussed and agreed on final revisions of the MUSA definitions. There was consensus on the need to distinguish between direct features of adenomyosis, i.e. features indicating presence of ectopic endometrial tissue in the myometrium, and indirect features, i.e. features reflecting changes in the myometrium secondary to presence of endometrial tissue in the myometrium. Myometrial cysts, hyperechogenic islands and echogenic subendometrial lines and buds were classified unanimously as direct features of adenomyosis. Globular uterus, asymmetrical myometrial thickening, fan-shaped shadowing, translesional vascularity, irregular junctional zone and interrupted junctional zone were classified as indirect features of adenomyosis. CONCLUSION Consensus between gynecologists with expertise in ultrasound diagnosis of adenomyosis was achieved regarding revised definitions of the MUSA features of adenomyosis and on the classification of MUSA features as direct or indirect signs of adenomyosis. © 2021 The Authors.

Learning Curve for the Detection of Deep Infiltrating Endometriosis and Adenomyosis with 3-D Transvaginal Water Contrast Sonography. ULTRASOUND IN MEDICINE & BIOLOGY 2022; 48:1328-1335. [PMID: 35469632 DOI: 10.1016/j.ultrasmedbio.2022.03.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 03/03/2022] [Accepted: 03/07/2022] [Indexed: 06/14/2023]
Abstract
Three-dimensional rectosonography (RSG) is a transvaginal sonography technique using rectal water contrast and 3-D acquisitions. The main points of interest of 3-D RSG could be its easy accessibility and its quick learning curve, especially with respect to rectosigmoid lesions. The objective of this prospective observational study was to assess the learning curve of 3-D RSG for the diagnosis of rectosigmoid lesions and for various other locations of deep endometriosis (DE), endometriomas and adenomyosis. From April 2017 to November 2017, 116 patients with suspected pelvic endometriosis were referred to the Croix-Rousse University Hospital, and those who underwent 3-D RSG were included in our study. After a short training period, four residents were asked to perform 3-D RSG by themselves. Each procedure was systematically controlled immediately afterward by a single expert sonographer. The success of the procedure involved the correct identification of various locations of endometriosis (rectosigmoid, uterosacral ligament, retrocervical space, vagina, bladder and ovaries) and adenomyosis, using the expert sonographer's examination as the reference technique. The learning curve was generated using these data and assessed using the Learning Curve Cumulative Summation Test (LC-CUSUM) method. The pooled LC-CUSUM revealed that the required level of achievement was reached after 24 3-D RSGs were performed for the diagnosis of rectosigmoid lesions. All four residents were significantly competent in diagnosing rectosigmoid lesions at the end of their training period, with an α risk <0.05 (T1, p = 0.03; T2, p = 0.0002; T3, p = 0.05; T4, p = 0.02). The LC-CUSUM analysis confirmed that competency was achieved for vaginal DE, torus uterinum DE, US DE, bladder DE, endometriomas and adenomyosis within 17, 27, 38, 19, 17 and 33 scans, respectively. This study provides evidence that the skills required to diagnose endometriosis lesions and adenomyosis with 3-D RSG can be acquired after a brief learning period in an expert center.

Application of Color Doppler Ultrasound in Microscopic Imaging Diagnosis of Adenomyosis. SCANNING 2022; 2022:2366871. [PMID: 35692699 PMCID: PMC9174001 DOI: 10.1155/2022/2366871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 05/08/2022] [Accepted: 05/13/2022] [Indexed: 06/15/2023]
Abstract
In order to explore the value of color Doppler ultrasonography (TVCDS) in the diagnosis and differential diagnosis of adenomyosis. A total of 150 patients with adenomyosis admitted to a hospital from January 2020 to December 2021 were selected, taking transvaginal three-dimensional color Doppler ultrasound and abdominal ultrasound for examination, all results were compared with patient pathology or surgical results, in order to compare the accuracy of the two inspection methods. The positive predictive value of three-dimensional color Doppler ultrasonography was higher than that of abdominal ultrasonography, and the difference was statistically significant (P < 0.05). The coincidence rate, sensitivity, and specificity of three-dimensional color Doppler ultrasonography were higher than those of abdominal ultrasonography, while the misdiagnosis rate was lower than that of abdominal ultrasonography, and the differences were statistically significant (all P < 0.05). The imaging features of vaginal three-dimensional color Doppler ultrasound in patients with adenomyosis are mainly enlarged uterus, slightly stronger echoes in the myometrium with enhanced echogenic spots, and short or short branch blood flow signals in the lesions. After statistical analysis, there was a significant difference in the blood flow changes between benign and malignant endometrial echoes and abnormal echoes in the uterine cavity, P < 0.05. Normal endometrium and benign intrauterine lesions mainly showed no blood flow signal, while malignant lesions in the uterine cavity mostly showed changes in blood flow signal. Compared with abdominal examination, transvaginal color Doppler ultrasonography has obvious advantages in the diagnosis of adenomyosis. According to the characteristics of ultrasound images, blood flow distribution, frequency spectrum, etc., it can provide a more accurate basis for clinical timely, provide the identification points of uterine fibroids, and provide help for clinicians to choose a treatment plan.

Abstract
A 37-year-old woman with a previous diagnosis of Mayer-Rokitansky-Kuster-Hauser syndrome at 18 years of age was referred from a primary healthcare physician to a gynaecology appointment in our centre. She presented with a 2-year worsening pelvic pain and dyspareunia, symptoms that were previously absent and, at the time, with inadequate relief with oral analgesia. Physical examination showed absent uterine cervix and hypoplastic superior vagina. Transvaginal ultrasound and MRI suggested the presence of an hypoplasic uterus in left rotation. Laparoscopically, two asymmetric rudimentary horns were found, united by a fibrous central band, with an enlarged and congestive left horn. The three structures were removed as a whole. Histopathological examination reported the presence of multiple adenomyotic foci along the full thickness of the left rudimentary horn. The patient had an uneventful postoperative recovery and full remission of her symptoms.

Diagnostic Accuracy of Transvaginal Ultrasound and Magnetic Resonance Imaging for Adenomyosis: Systematic Review and Meta-Analysis and Review of Sonographic Diagnostic Criteria. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2021; 40:2289-2306. [PMID: 33502767 DOI: 10.1002/jum.15635] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Revised: 12/16/2020] [Accepted: 01/02/2021] [Indexed: 05/14/2023]
Abstract
We aim to first systematically review and perform a meta-analysis of the diagnostic accuracy of transvaginal ultrasound (TVUS) and magnetic resonance imaging (MRI) and, second, to evaluate the accuracy of various sonographic diagnostic criteria for adenomyosis. A search of PubMed and Embase yielded 32 eligible studies. In diagnosing adenomyosis, the diagnostic performance of TVUS was found to be high and comparable to the performance of MRI. Of the eight sonographic criteria, only five were assessable. The best individual criterion was echogenic subendometrial lines and buds. Limited data exist for the various sonographic criteria, and further studies are required to compare their performance.

[Diffusion-weighted magnetic resonance imaging instead of contrast-enhanced imaging for evaluating immediate therapeutic efficacy of high-intensity focused ultrasound ablation of adenomyosis]. NAN FANG YI KE DA XUE XUE BAO = JOURNAL OF SOUTHERN MEDICAL UNIVERSITY 2021; 41:1583-1587. [PMID: 34755676 PMCID: PMC8586868 DOI: 10.12122/j.issn.1673-4254.2021.10.19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To explore the feasibility of diffusion-weighted magnetic resonance imaging (DWI) instead of contrast-enhanced (CE) imaging for evaluation of the immediate therapeutic efficacy of high-intensity focused ultrasound (HIFU) ablation for treatment of adenomyosis. METHODS We retrospectively analyzed the data of 29 patients aged 40.5 ± 5.4 years under going HIFU treatment for adenomyosis in our hospital between December, 2017 and July, 2020. The patients received MRI examination both before and within 24 h after the operation. Two observers analyzed the morphology of the ablation area on DWI and classified the lesions into type 1 (spot-like or no obvious signal intensity changes), type 2 (patchy signal intensity changes) and type 3 (ring-like signal intensity changes). The inter- and intra-observer reliability of morphological assessment was assessed using kappa test. The volume of necrotic tissues following the ablation was measured with both DWI and CE imaging, and the consistency of the measurements and the inter- and intra-observer reliability of DWI-based measurements were evaluated using Bland-Altman plot tests. RESULTS The median volume of necrotic tissues was 36.9 cm3 (range 16.4-65.5 cm3) following ablation of the 29 lesions. DWI findings identified 24-25 (82.8%-86.2%) lesions with type 2 or 3 signal changes following the ablation with measurable necrotic tissue volume. On DW images, the Kappa value of intra- and inter-observer reliability for morphological classification of the ablation area reached 0.798 (P=0.000) and 0.933 (P= 0.000), respectively. Bland-Altman plots showed a good consistency of the necrotic volumes measured by CE and at DWI with a strong inter- and intra-observer reliability of DWI-based volume measurements (with only one point outside the range of 95% limits of agreement). The remaining 4 or 5 lesions, which presented with type 1 signal changes following ablation, were all small in size (the largest was only 18.61 cm3) and showed poor therapeutic responses to the ablation. CONCLUSION DWI-based morphological assessment and necrotic tissue volume measurement can replace CE imaging for assessment of the immediate therapeutic efficacy of HIFU ablation for treatment of adenomyosis.

The suture fixation of levonorgestrel-releasing intrauterine device using the hysteroscopic cold-knife surgery system: an original method in treatment of adenomyosis. Fertil Steril 2021; 116:1191-1193. [PMID: 34238576 DOI: 10.1016/j.fertnstert.2021.05.113] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Revised: 05/22/2021] [Accepted: 05/28/2021] [Indexed: 11/18/2022]
Abstract
OBJECTIVE To introduce an effective approach using the hysteroscopic cold-knife surgery system (HCSS) for suture fixation of the levonorgestrel-releasing intrauterine device (LNG-IUD) in patients with adenomyosis. DESIGN Video description of the surgical procedures to demonstrate the detailed technique. The study was reviewed and approved by the institutional review board of Hangzhou Women's Hospital. SETTING Maternity hospital. PATIENT(S) A 39-year-old woman diagnosed with adenomyosis had endured 7 years of severe dysmenorrhea and 4 years of heavy menstrual bleeding. She had a past medical history that was significant for expulsion of an LNG-IUD. Transvaginal ultrasonography revealed that her uterus was enlarged by adenomyosis. She insisted on preserving fertility potential. INTERVENTION(S) We proceeded with the HCSS and the uterine cavity was found enlarged significantly. In consideration of the patient's strong desire for maintaining fertility options, the fixation of the LNG-IUD on the intrauterine posterior wall with an Ethibond suture was performed successfully through an endoscopic needle driver and a knot-pushing device. Proficient endoscopic suturing is the key to the technique. Informed consent was obtained from the patient. MAIN OUTCOME MEASURE(S) Feasibility and value of using the HCSS to fix an LNG-IUD for treatment of adenomyosis. RESULT(S) The LNG-IUD was fixed successfully by the HCSS with an Ethibond suture on the posterior wall of the uterus within 30 minutes, and the intraoperative blood loss was 2 mL. The patient was discharged 24 hours postoperatively without any adverse perioperative complications. At the one-year follow-up, the patient reported obvious relief of her dysmenorrhea and menorrhagia and no more experience with expulsion. Ultrasound demonstrated normal position of the IUD at 1, 3, 6, and 12 months postoperatively. CONCLUSION(S) Hysteroscopy presents a clear visual field to locate and fix the IUD. In patients with adenomyosis suffering from dysmenorrhea or excessive menstrual blood loss, suture fixation of the LNG-IUD using the HCSS can be a minimally invasive and effective alternative for treating adenomyosis, especially in patients who have previously expelled an LNG-IUD, preventing the risk of expulsion.

Abstract
OBJECTIVE Adenomyosis is a benign uterine disorder characterized by the invasion of the endometrium within the myometrium, starting from the junctional zone (JZ), the inner hormone dependent layer of the myometrium that plays an important role in sperm transport, implantation and placentation. The resulting histological abnormalities and functional defects may represent the pathogenic substrate for infertility and pregnancy complications. The objective of this paper is to review the literature to evaluate the correlation between inner myometrium alterations and infertility and to assess the role of JZ in the origin of adverse obstetric outcomes of both spontaneous and in vitro fertilization (IVF) pregnancies. METHODS we searched Pubmed for all original and review articles in the English language from January1962 until December 2019, using the MeSH terms of 'adenomyosis', 'junctional zone', combined with 'infertility', 'obstetrical outcomes', 'spontaneous conception', 'in vitro fertilization' and 'classification'. The review was divided into three sections to assess this pathogenic correlation, evaluating also the importance of classification of the disease. RESULTS AND CONCLUSIONS Absent or incomplete remodeling of the JZ can affect uterine peristalsis, alter vascular plasticity of the spiral arteries and activate inflammatory pathways, all related to adverse obstetric outcomes. Despite these observations, there is still limited evidence whether adenomyosis is a cause of infertility. However, it is reasonable to screen patients for adenomyosis, to consider pregnant women with diffuse adenomyosis at high risk of adverse obstetric outcomes, and to evaluate the importance of a noninvasive validated classification in the management of women with adenomyosis.

Effects of localisation of uterine adenomyosis on outcome of in vitro fertilisation/intracytoplasmic sperm injection fresh and frozen-thawed embryo transfer cycles: a multicentre retrospective cohort study. Reprod Biol Endocrinol 2021; 19:84. [PMID: 34088314 PMCID: PMC8176737 DOI: 10.1186/s12958-021-00764-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Accepted: 05/19/2021] [Indexed: 12/26/2022] Open
Abstract
BACKGROUND Uterine adenomyosis is a benign disease, common among women in their 40 and 50 s, characterised by ectopic endometrial tissue in the uterine myometrial layer. Adenomyosis causes infertility and has a negative effect on the outcomes of in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) embryo transfer (ET) cycles. It has also been reported to have different characteristics depending on the adenomyotic lesion localisation. The effect of its localisation on IVF/ICSI-ET outcomes is unclear. This study aimed to investigate whether adenomyotic lesion localisation, assessed using magnetic resonance imaging (MRI), was associated with outcomes of IVF/ICSI-ET cycles. METHODS This multicentre, joint, retrospective cohort study analysed the medical records of 67 infertile patients with adenomyosis who underwent IVF/ICSI with fresh and frozen-thawed ET at five participating facilities from January 2012 to December 2016 and for whom MRI data were available. Fifteen patients were excluded; therefore, the MRI data of 52 patients were evaluated by two radiologists. We assessed the localisation of and classified adenomyotic lesions into advanced (invades the full thickness of the uterine myometrium), extrinsic (localised on the serosal side), and intrinsic (localised on the endometrial side) subtypes. RESULTS There were 40 advanced, nine extrinsic, and three intrinsic cases, and the outcomes of 100, 27, and nine ET cycles, respectively, were analysed. Pregnancy loss/clinical pregnancy and live birth rates of the advanced, extrinsic, and intrinsic groups were 64 % (16/25) and 9 % (9/100), 33.3 % (3/9) and 22.2 % (6/27), and 50 % (1/2) and 11.1 % (1/9), respectively. A logistic regression analysis adjusted for age, prior miscarriage, and body mass index showed that the extrinsic group had fewer pregnancy losses (odds ratio 0.06; 95 % confidence interval [CI]: 0.00-0.54, p = 0.026) and more live births (odds ratio 6.05; 95 % CI: 1.41-29.65, p = 0.018) than the advanced group. CONCLUSIONS Adenomyotic lesions exert different effects on IVF/ICSI-ET outcomes. Thus, MRI assessments of adenomyosis in infertile patients are beneficial. Establishment of treatment plans based on adenomyotic lesion localisation should be considered.
