Adenomyosis: An update regarding its diagnosis and clinical features

Diagnosing adenomyosis using transvaginal ultrasound in current practice: A scoping review and service evaluation

Background

A departmental audit identified a case of adenomyosis which had not been reported, highlighting the need to assess whether the current service provision is adequate in identifying patients with (possible) adenomyosis and how improvements in this part of the service could be made.

Aim

To assess whether sonographers are effectively identifying and reporting adenomyosis on transvaginal ultrasound.

Methodology

A scoping review and retrospective service evaluation was undertaken which included (n = 79) adult female premenopausal patients with symptoms of adenomyosis who had undergone a transvaginal ultrasound scan during the first quarter of 2023. Patients were identified using the CRIS statistic module according to pre-defined inclusion and exclusion criteria. All data were anonymised and collated to include the patient age, referral information (symptoms), scan report and sonographer. The scan report and archived images were evaluated using the sonographic signs identified by the Morphological Uterus Sonographic Assessment group (Harmsen et al., 2022) and then compared to the original report.

Results

In total, 21.5% (n = 17) of patients had signs of adenomyosis on image review, but only 23.5% (n = 4) of these were reported as such. The majority (n = 8) of unidentified cases were reported as having a 'heterogeneous myometrium'. Inter-rater agreement ranged from 50% to 100%.

Conclusion

Most ultrasonic diagnoses of adenomyosis were not identified in our service which is likely due to a lack of internationally agreed criteria for ultrasound diagnosis of adenomyosis preventing adequate reporting.

Analysis of cumulative live birth rate outcomes of four ovarian stimulation protocols in Poseidon groups 3/4 patients with adenomyosis

PURPOSE

To compare the effects of the gonadotrophin-releasing hormone (GnRH) agonist protocol, GnRH antagonist protocol, progestin-primed ovarian stimulation (PPOS) protocol, and mild stimulation/natural cycle protocol on the cumulative live birth rate (CLBR) in patients with adenomyosis and Poseidon group 3/4.

METHODS

A total of 1090 patients diagnosed with adenomyosis and Poseidon groups 3/4 group who underwent in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) from January 2013 to December 2020 were included. Demographic characteristics, laboratory indicators, and clinical outcomes of the four ovarian stimulation protocols were compared. The primary outcome was the CLBR, with binary logistic regression analysis used to explore the factors influencing CLBR.

RESULTS

Among the patients with adenomyosis and Poseidon groups 3/4, the CLBR in GnRH agonist protocol group was higher than that in PPOS protocol group (45.78% vs. 22.33%, P = 0.005). Binary logistic regression analysis revealed that GnRH agonist protocol had a higher CLBR compared to PPOS protocol (adjusted odds ratio (aOR) 3.26, 95% confidence interval (CI): 1.56-6.83, P = 0.002), while no significant differences were found when comparing PPOS protocol with GnRH antagonist protocol (P = 0.093) and mild stimulation/natural cycle protocol (P = 0.125). In the < 35 years subgroup, the CLBR of GnRH agonist protocol was significantly higher (55.26% vs. 33.82%; P = 0.032), which wasn't observed in elder subgroups (P > 0.05).

CONCLUSION

For patients with both adenomyosis and Poseidon groups 3/4, GnRH agonist protocol showed a higher CLBR, especially in patients < 35 years (Poseidon group 3).

Regulation on mitophagy in adenomyosis by Guizhi Fuling Wan

ETHNOPHARMACOLOGICAL RELEVANCE

Guizhi Fuling Wan (GZFLW), a canonical herbal formulation originating from Synopsis of the Golden Chamber, has been widely utilized in managing pain-associated disorders. While its therapeutic efficacy in adenomyosis (AM) characterized by severe dysmenorrhea is well-documented, the underlying pharmacological mechanisms remain elusive. Emerging evidence suggests that hypoxic mitochondrial damage in endometrial tissue constitutes a pathological hallmark of AM, wherein mitophagy regulation through the PINK1/Parkin signaling pathway plays a pivotal role in mitochondrial quality control. Although certain phytomedicines have demonstrated mitophagy-modulating properties under hypoxic conditions, the specific regulatory effects of GZFLW on this process in AM pathogenesis warrant systematic investigation.

AIM OF THE STUDY

To elucidate the mitophagy-modulating mechanism of GZFLW in AM through integrated in vivo and in vitro approaches.

MATERIALS AND METHODS

An allogeneic pituitary transplantation-induced AM mouse model was established. Pharmacodynamic assessment included hotplate testing and serum cancer antigen 125 (CA125) quantification, while blood urea nitrogen (BUN) and alanine aminotransferase (ALT) levels were monitored for hepatorenal toxicity screening. Histopathological characterization employed hematoxylin-eosin (H&E) staining and transmission electron microscopy (TEM) for ultrastructural analysis. Protein expression of PINK1/Parkin pathway components (PINK1, Parkin, OPTIN, NDP52, P62) were determined by Western blot. Primary endometrial stromal cells (ESCs) isolated from clinical AM specimens underwent functional assessment via transwell migration/invasion assays, complemented by flow cytometric quantification of mitochondrial membrane potential (MMP) and reactive oxygen species (ROS). Molecular docking simulations evaluated ligand-receptor interactions between GZFLW bioactive constituents and PINK1/Parkin proteins. This study protocol was approved by the Medical Ethics Committee of China Three Gorges University (No. 2022CA002).

RESULTS

Histopathological validation confirmed successful AM model establishment. ELISA revealed significantly elevated CA125 levels in AM mice versus controls (P < 0.05), with notable reductions in GZFLW-treated groups (GET: P < 0.05, GZFLW-L: P < 0.01). No intergroup differences emerged in ALT/BUN levels, indicating absence of hepatorenal toxicity. Post-modeling pain threshold depression (P < 0.05 vs control) was attenuated by GZFLW treatment (P < 0.05). TEM analysis demonstrated mitochondrial pathology in AM endometrium, including structural deformation, reduced mitochondrial quantity, and autophagosome accumulation, all ameliorated by GZFLW-L intervention. Western blot showed upregulated PINK1 (P < 0.01), Parkin, OPTIN, and NDP52 (P < 0.05) in AM group, with subsequent downregulation following GZFLW-L administration (P < 0.05). In vitro, AM ESCs exhibited MMP depolarization (P < 0.05), reversed by GZFLW treatment alongside suppressed migratory/invasive capacity (P < 0.01, P < 0.05), ROS reduction (P < 0.05), and attenuated PINK1/Parkin pathway activation. Molecular docking confirmed strong binding affinities (binding energy < -5.0 kcal/mol) between GZFLW phytoconstituents and PINK1/Parkin targets.

CONCLUSION

This investigation reveals that GZFLW exerts its therapeutic effects on AM via targeted modulation of the PINK1/Parkin-mediated mitophagy axis, supporting its potential as a mitochondria-targeted therapeutic strategy for AM management.

Evaluation of Long-COVID Syndrome in a Cohort of Patients with Endometriosis or Adenomyosis

Background: Long-COVID is characterized by the persistency of COVID-19 symptoms beyond 12 weeks, and it is probably consequent to immune dysregulation induced by SARS-CoV-2 infection. Immune dysregulation is associated with and probably involved in the pathogenesis of chronic gynecological conditions like endometriosis and adenomyosis. This study evaluated whether the presence of endometriosis or adenomyosis increases the risk of long-COVID, i.e., the persistence of COVID-19 symptoms beyond 12 weeks since infection. Methods: This retrospective observational study was performed at the outpatient service for endometriosis and chronic pelvic pain, at a university hospital. The diagnosis of endometriosis/adenomyosis was primarily based on clinical symptoms and ultrasonography assessment. Data regarding infection, vaccination, symptoms associated with SARS-CoV-2 infection, and their persistence for a minimum of 12 weeks were collected. Results: This study included 247 women, 149 controls without and 98 cases with endometriosis/adenomyosis. Among these, 194 (116 controls and 78 cases) had suffered from SARS-CoV-2 infection. Rates of infection and vaccination were similar in the two groups. The distribution of the SARS-CoV-2 vaccine was uniform across the two cohorts. COVID-19 patients with endometriosis or adenomyosis exhibited a higher prevalence (p < 0.001) of dyspnea and chest pain. The prevalence of long-COVID beyond 12 weeks was higher in cases than controls (42% vs. 12%; p < 0.001) with chest pain (p < 0.001) and ageusia (p < 0.05), forming the most representative symptoms. Conclusions: Symptoms of long-COVID are more frequent in women with than without endometriosis/adenomyosis.

Endometriosis and adenomyosis research priorities in India and Sri Lanka: a call for regional collaboration

Endometriosis and adenomyosis are major gynaecological conditions affecting women of reproductive age-group, particularly in low- and middle-income countries. This Health Policy outlined research priorities for India and Sri Lanka, derived from a structured debate during the 'Future Directions in Endometriosis and Adenomyosis Research' workshop. Researchers from both countries emphasise the need for nationally representative data, improved diagnostic tools, and comprehensive care models. Shared priorities include developing patient registries and improving healthcare access. India focuses on multidisciplinary care centres, advanced diagnostic research, and public education, while Sri Lanka highlights integrating traditional medicine and assessing economic impacts. Both countries prioritise non-invasive diagnostics to address diagnostic delays and healthcare limitations. Establishing patient registries and consortiums for large-scale studies could inform healthcare strategies. Collaborative research among Asian countries could generate tailored regional solutions. Coupled with a strong political will, and adequate funding, the initiative can potentially improve diagnosis, treatment, and quality of life for affected women.

The clinical efficacy and influencing factors of uterine artery embolization in the treatment of different types of uterine adenomyosis

Uterine adenomyosis, a common benign tumor disease in gynecology, mainly manifested as chronic pelvic pain, menstrual disorders, dysmenorrhea, etc., has a great impact on patients' daily life and work. Compared with traditional surgery and drug therapy, uterine artery embolization (UAE), as a new treatment with less trauma, faster recovery and uterine preservation, can relieve pain while preserving normal physiological and reproductive functions of the uterus, which is favored by the majority of patients. In this study, the patients were divided into two groups based on magnetic resonance imaging (MRI) test. Their serum CA125 level was detected, and the degree of symptom relief and health index were evaluated, aiming to explore the clinical efficacy and influencing factors of UAE in the treatment of adenomyosis. The results showed that before UAE, CA125 level in group B was significantly higher than that in group A, and 2 days after UAE, CA125 level in both groups was lower than before treatment, indicating that the serum CA125 level may be related to the type of adenomyosis, but UAE has a good therapeutic effect on both focal and diffuse adenomyosis. 3 months after interventional treatment, the patients had significantly reduced symptoms with dramatically improved health status and the VAS pain score was significantly reduced, indicating that UAE can significantly improve the clinical symptoms of patients with adenomyosis. Uterine artery embolization was performed in both groups. No serious complications occurred during the operation, and the technical success rate reached 100%. In summary, UAE, as a minimally invasive treatment, has obvious and significant clinical effects in the treatment of adenomyosis, and is an important alternative treatment for adenomyosis.

Medical treatment before in-vitro fertilization in patients with adenomyosis: a systematic review and meta-analysis

The objective of this study is to evaluate if medical treatment before assisted reproductive technology (ART) improves the results in infertile patients with adenomyosis. A literature search was performed with EMBASE, PubMed, and Cochrane. The primary outcome was clinical pregnancy rate (CPR). Secondary outcomes were live birth rate (LBR) per cycle and miscarriage rate (MR) after ART with or without medical pretreatment. Additionally, a comparison was made between women undergoing medical pretreatment before frozen embryo transfer (FET) and those who underwent FET alone, including any type of endometrial preparation. Ten studies were included. The present meta-analysis supports the use of long-term GnRH agonist therapy in patients with adenomyosis, which enhances the CPR (odds ratio (OR) 1.49, 95% CI 1.15 to 1.92) in IVF/ICSI with fresh ET, while the comparison in women undergoing FET cycles did not reach statistical significance (OR 1.34 95% CI 0.70-2.55). Pretreatment with GnRH agonist did not demonstrate a benefit on the LBR and MR per cycle in IVF/ICSI with fresh ET in comparison to standard ovarian stimulation protocols. Similar results were observed in the setting of FET, failing to indicate a superiority of GnRH agonist pretreatment over standard FET protocols for LBR and MR. In conclusion, GnRH agonist pretreatment before ART carries a potential benefit in improving outcomes in terms of higher CPR, but there is no significant impact on LBR and MR. Pretreatment with GnRH agonists could be adopted as a possible alternative ART protocol in selected patients with adenomyosis and infertility.

Epidemiology of endometriosis in Kazakhstan: a national population-based cohort analysis (2014-2019) using data from the national electronic healthcare system

Background

Endometriosis is a condition affecting reproductive-age women and associated with dysmenorrhea, pelvic organs dysfunction, pelvic pain, and infertility. The real epidemiology of endometriosis remains underestimated. No data are available on prevalence of endometriosis in Kazakhstan. Therefore, the aim of this was to investigate the epidemiology, complications, surgical management approach, and outcomes of endometriosis in Kazakhstan by analyzing large-scale Kazakhstani healthcare data from the Unified Nationwide Electronic Health System (UNEHS).

Methods

A population-based study among women with endometriosis treated in any healthcare setting of the Republic of Kazakhstan during the period of 2014-2019 was performed. The International Classification of Diseases (ICD) 10th edition was used to retrieve data on endometriosis ("N80" and "N97"). ICD 9th edition's procedural codes were utilized to retrieve information on surgical procedures performed to manage patients with endometriosis.

Results

In total, 7,682 records of women diagnosed with endometriosis were analyzed from all Kazakhstani regions. The overall prevalence of endometriosis among Kazakhstani female population was 0.12%, with 50.1% of them suffering from endometriosis of the uterus, 34.5% with ovarian endometriosis, and 9.5% with endometriosis of pelvic peritoneum. The most affected group was reproductive-age women (25-44 years old). Endometriosis rates were higher among women of 35-39, 40-44, and 45-49 years old age groups - 0.4 per 1000 women of corresponding age. The most common procedures performed for surgical management were laparoscopic cystectomy and closed biopsy of the uterus, 16.4 and 13.5%, respectively.

Conclusion

Among all registered cases of endometriosis, ovarian endometriosis is the most prevalent condition. However, the analysis of the UNEHS records on endometriosis reveals incomplete and inconsistent registration of the disease, which results in the underestimation of the disease's real burden. Clinical specialist and health authorities in Kazakhstan must work to ensure the endometriosis proper diagnosis end registration to improve the disease management and outcomes.

MRI for endometriosis in adolescent patients

Endometriosis, a chronic condition that often starts in adolescence, can have a significant impact on quality of life due to symptoms of dysmenorrhea and pelvic pain. Although laparoscopy with direct visualization and pathologic correlation is the reference standard for the diagnosis of endometriosis, some authors have called for a greater emphasis on clinical diagnosis - including imaging. Magnetic resonance imaging (MRI) provides highly reproducible, large field of view, multiplanar, and multiparametric imaging of pelvic endometriosis and is well tolerated in adolescent patients. As such, pediatric radiologists need to be familiar with the manifestations of endometriosis on MRI and how these findings may differ from those seen in adult populations.

Management of Common Benign Gynecologic Diseases in Postmenopausal Women

This study investigated the impact of menopause on the progression and management of common benign gynecological conditions such as polycystic ovary syndrome, endometriosis, uterine fibroids, and adenomyosis. These conditions often present with menstruation-related symptoms such as irregular cycles, heavy bleeding, and pelvic pain. While these symptoms typically subside after menopause, the underlying pathology of such benign gynecological conditions may be differentially affected by the physiological changes associated with menopause, sometimes leading to exacerbation or additional management challenges. Although rare, the potential for malignant transformation remains a concern. This study aims to elucidate the shifts in management strategies from the reproductive years to postmenopause. It highlights the necessity for a tailored approach to hormone therapy and surgical interventions based on the individual patient's health profile and the specific characteristics of each condition.

Adenomyosis Localized in Both the Anterior and Posterior Myometrium Is Associated with Deep Rectal Endometriosis: A Retrospective Study

BACKGROUND

Endometriosis and adenomyosis are two closely related, estrogen-dependent, benign gynecological diseases. The available evidence on their common pathogenesis and association is limited and often does not address the heterogeneity of both entities. The aim of our study is to investigate the association between different types and localizations of adenomyosis and endometriosis phenotypes, using magnetic resonance imaging (MRI) and laparoscopic findings.

METHODS

We performed a retrospective observational study involving premenopausal women over 18 years old who underwent laparoscopic surgery for endometriosis and were pre-operatively diagnosed with adenomyosis through MRI examination at the Cantonal Hospital of Schaffhausen, Switzerland between 2011 and 2022.

RESULTS

Of 130 patients with adenomyosis, 23 (17.7%) women had adenomyosis only in the anterior wall (group 1), 38 (29.2%) only in the posterior wall (group 2), and 69 (53.1%) in both the anterior and posterior wall (group 3). Women in group 1 experienced significantly more dysuria compared to the two other groups (p = 0.018), while the prevalence of other pain symptoms (dysmenorrhea, dyspareunia, dyschesia) was comparable between the groups. Women in group 3 had significantly thicker anterior and posterior myometrium compared to groups 1 and 2 (p < 0.001). Co-existence of deep rectal endometriosis was more frequent in women from group 3 compared to groups 1 and 2 (p = 0.039) and in women with adenomyosis in the outer (extrinsic) compared to adenomyosis in the inner myometrium (intrinsic) (p < 0.001).

CONCLUSIONS

This study provides evidence of an association between the localization of adenomyosis and the distribution of concomitant endometriosis. Specifically, adenomyosis localized in both the anterior and posterior wall appears to be more proliferative compared to adenomyosis found only in the anterior or posterior wall. This is indicated by its association with higher uterine volume, thicker posterior junctional zone, and greater myometrial thickness and with a higher co-existence with deep rectal endometriosis. These findings support an association between the development of specific subtypes of both entities, which represents a valuable resource for the identification of future targets for the treatment and clinical management of adenomyosis and endometriosis.

Adenomyosis and Adolescence: A Challenging Diagnosis and Complex Management

Adenomyosis is a chronic, hormone-related disease characterized by the presence of the endometrial glands and stroma within the myometrium. This condition can manifest in various features, focal or diffuse adenomyosis or as an adenomyoma, and it may involve different uterine walls (posterior, anterior, and/or lateral walls). The disease can also be classified into different degrees, as mild, moderate and severe, which can be associated with more intense symptoms, although this correlation is not always directly proportional. In fact, adenomyosis can be asymptomatic in about a third of cases or it can significantly impact patients' quality of life through painful symptoms, such as dysmenorrhea and dyspareunia, abnormal uterine bleeding-particularly heavy menstrual bleeding-and potential effects on fertility. Historically, adenomyosis has been considered a disease primarily affecting premenopausal women over the age of 40, often multiparous, because the diagnosis was traditionally based on surgical reports from hysterectomies performed after the completion of reproductive desire. Data on the presence of adenomyosis in adolescent patients remain limited. However, in recent years, advancements in noninvasive diagnostic tools and increased awareness of this pathology have enabled earlier diagnoses. The disease appears to have an early onset during adolescence, with a tendency to progress in terms of extent and severity over time. Adenomyosis often coexists with endometriosis, which also has an early onset. Therefore, it is important, when diagnosing adenomyosis, to also screen for concomitant endometriosis, especially deep endometriosis in the posterior compartment. The aim of this narrative review is to investigate the prevalence of different types and degrees of adenomyosis in younger patients, assess the associated symptoms, and describe the most appropriate diagnostic procedures for effective therapeutic management and follow-up, with the goal of improving the quality of life for these young women.

Eutopic and Ectopic Endometrial Interleukin-17 and Interleukin-17 Receptor Expression at the Endometrial-Myometrial Interface in Women with Adenomyosis: Possible Pathophysiology Implications

Adenomyosis involves the infiltration of endometrial glands and stroma deep into the uterine tissue, causing disruption to the endometrial-myometrial interface (EMI). The role of interleukin-17 (IL-17) has been extensively studied in endometriosis, but its involvement in adenomyosis remains unclear. This study aimed to investigate the expression of IL-17 in eutopic and ectopic endometrium (adenomyosis) of individuals with adenomyosis at the level of EMI. Paired tissues of eutopic endometrium and adenomyoma were collected from 16 premenopausal women undergoing hysterectomy due to adenomyosis. The IL-17 system was demonstrated in paired tissue samples at the level of EMI by the immunochemistry study. Gene expression levels of IL-17A and IL-17 receptor (IL-17R) were assessed through quantitative real-time reverse transcription polymerase chain reaction (RT-PCR). Comparative gene transcript amounts were calculated using the delta-delta Ct method. By immunohistochemical staining, CD4, IL-17A, and IL-17R proteins were detected in both eutopic endometrium and adenomyosis at the level of EMI. IL-17A and IL-17R were expressed mainly in the glandular cells, and the expression of both IL-17A and IL-17R was found to be stronger in adenomyosis than in endometrium. 3-Diaminobenzidine (DAB) staining revealed greater IL-17A expression in adenomyosis compared to eutopic endometrium. Quantitative RT-PCR showed 7.28-fold change of IL-17A and 1.99-fold change of IL-17R, and the fold change level of both IL-17A and IL-17R is significantly higher in adenomyosis (IL-17A: p = 0.047, IL-17R: p = 0.027) versus eutopic endometrium. We found significantly higher IL-17 levels in adenomyosis compared to eutopic endometrium at the level of EMI. The results showed that the IL-17 system may play a role in adenomyosis.

Automatic diagnosis for adenomyosis in ultrasound images by deep neural networks

OBJECTIVE

To present a new noninvasive technique for automatic diagnosis of adenomyosis, using a novel end-to-end unified network framework based on transformer networks.

STUDY DESIGN

This is a prospective descriptive study conducted at a university hospital.1654 patients were recruited to the study according to adenomyosis diagnosed by transvaginal ultrasound (TVS). For adenomyosis characteristics and ultrasound images, automatic identification of adenomyosis were performed based on deep learning methods. We called this unique technique A2DNet: Adenomyosis Auto Diagnosis Network.

RESULTS

The A2DNet exhibits excellent performance in diagnosis of adenomyosis, achieving an accuracy of 92.33%, a precision of 96.06%, a recall of 91.71% and an F1 score of 93.80% in the test group. The confusion matrix of experimental results show that the A2DNet can achieve a correct diagnosis rate of 92% or more for both normal and adenomyosis samples, which demonstrate the superiority of the A2DNet comparing with the state-of-the-arts.

CONCLUSION

The A2DNet is a safe and effective technique to aid in automatic diagnosis of adenomyosis. The technique which is nondestructive and non-invasive, is new and unique due to the advantages of artificial intelligence.

Alternative treatments of adenomyosis - an update in procedural management and clinical outcomes

PURPOSE OF REVIEW

Adenomyosis is a common cause of abnormal uterine bleeding (AUB), dysmenorrhea, and pelvic pain. Definitive diagnosis and treatment have historically been by uterine histopathology at time of hysterectomy; however, advances in imaging have supported earlier diagnosis and subsequent conservative treatment. This review aims to update the evidence supporting the uterine-sparing, procedural management options with a focus on clinical outcomes.

RECENT FINDINGS

Uterine artery embolization (UAE), radiofrequency ablation (RFA), high-intensity focused ultrasound (HIFU), percutaneous microwave ablation (PMWA), and adenomyomectomy are minimally invasive interventions proven to be effective in reducing AUB and dysmenorrhea due to adenomyosis. Symptom improvement is associated with a decrease in uterine volume. Studies support the use of alternative treatment options given the overall low rates of symptom recurrence and reintervention. Combination therapy may be more effective than monotherapy.

SUMMARY

This review provides the current evidence for use of alternative treatment options for adenomyosis. Access to ablative therapies in the USA is limited and primarily off label, given lack of FDA approval. High-quality prospective and randomized controlled trials are needed in order to further delineate treatment comparisons, efficacy, safety, and ideal patient selection for these treatments. More data are needed to assess safety and utility in those desiring future fertility.

Prevalence of adenomyosis features in women scheduled for assisted reproductive treatment, using the Morphological Uterus Sonographic Assessment group definitions

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.

Knowledge, attitudes, and practices among Chinese reproductive-age women toward uterine adenomyosis

Objective

This study aimed to assess the knowledge, attitudes and practices (KAP) among Chinese reproductive-age women toward uterine adenomyosis.

Methods

This web-based cross-sectional study was conducted between April 2023 and September 2023 at the Second Hospital of Hebei Medical University. A self-designed questionnaire was developed to collect demographic information of reproductive-age women, and assess their KAP toward uterine adenomyosis.

Results

A total of 520 valid questionnaires were collected. Among the participants, 127 (24.42%) were diagnosed with uterine adenomyosis, and 120 (23.08%) were accompanied by uterine fibroids. The mean knowledge, attitudes and practices scores were 3.54 ± 3.72 (possible range:0-10), 20.96 ± 3.19 (possible range:5-25) and 24.01 ± 4.95 (possible range:7-35), respectively. The structural equation model demonstrated that knowledge had direct effects on attitudes and practices, as indicated by a path coefficient of 0.714 (p < 0.001) and 1.510 (p < 0.001), respectively. Moreover, attitudes had direct effects on practices, with a path coefficient of 0.226 (p = 0.001).

Conclusion

The findings revealed that reproductive-age women have insufficient knowledge, negative attitudes, and poor practices toward the uterine adenomyosis. Comprehensive training programs are needed to improve reproductive-age women practices in this area.

Microwave ablation for diffuse adenomyosis leading to multiple complications after hysterectomy: A case report and literature review

RATIONALE

Hysterectomy after microwave ablation (MWA) is more difficult than conventional surgery which increases the probability of postoperative complications due to MWA's collateral thermal damage to nearby intestines. Here we report a case of multiple postoperative complications after hysterectomy following MWA.

PATIENT CONCERNS

A 44-year-old female was admitted due to progressive abdominal pain during menstruation for 30 years and no relief 1 year after MWA. Hysterectomy was performed. Intraoperative findings: pelvic inflammatory exudation; the uterus and the left adnexa were extensively and densely adhered to the intestine, bladder, pelvic wall and surrounding tissues; the local tissue of the uterus was brittle and dark yellow. Intestinal obstruction, abdominal infection and urinary fistula occurred after hysterectomy.

DIAGNOSES

1. Adenomyosis. 2. Endometrial polyps. 3. Left chocolate cyst of ovary. 4. Pelvic adhesions. 5. Pelvic inflammation.

INTERVENTIONS

The patient underwent intestinal obstruction catheter implantation, ultrasound-guided pelvic fluid mass puncture drainage, right kidney puncture and fistula drainage, right ureteral bladder replantation, and right ureteral stent implantation.

OUTCOMES

After 48 days of comprehensive treatment, the patient was cured and discharged.

LESSONS

Microwave ablation has a poor therapeutic effect on diffuse adenomyosis, and should avoid excessive ablation during the ablation process.

Efficacy of etonogestrel subcutaneous implants versus the levonorgestrel-releasing intrauterine system in the conservative treatment of adenomyosis

To evaluate the clinical efficacy of etonogestrel subcutaneous implant (ENG-SCI) with that of the levonorgestrel-releasing intrauterine system (LNG-IUD) for adenomyosis treatment. A prospective randomized cohort study was conducted including 108 patients (50 patients in ENG-SCI group and 58 in the LNG-IUD group) with adenomyosis from January 2019 to July 2021. After 3 months of treatment, both ENG-SCI group and LNG-IUD group showed significant improvement in patients' visual analog scale, pictorial blood loss assessment chart (PBAC), and uterine volume (P ＜ 0.05). The uterine volume of patients in LNG-IUD group decreased more significantly than that in the ENG-SCI group since 3 months of treatment. The PBAC score in the LNG-IUD group improved better than that in the ENG-SCI group since 6 months of treatment (P ＜ 0.05). No significant difference in the occurrence rate of ideal vaginal bleeding patterns and the hemoglobin levels between the two groups was observed. The ENG-SCI group had a higher probability of weight gain and progesterone-related side effects (P ＜ 0.05). Both ENG-SCI and LNG-IUD were effective in treatment of adenomyosis. However, LNG-IUD had a more significant effect in treating adenomyosis-related dysmenorrhea, excessive menstrual flow, anemia, and uterine enlargement, with relatively fewer side effects.

The "freeze-all" strategy seems to improve the chances of birth in adenomyosis-affected women

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.

Treatment of adenomyosis, abdominal wall endometriosis and uterine leiomyoma with interventional radiology: A review of current evidences

Interventional radiology shows promises in the field of women's health, particularly in pelvic interventions. This review article discusses the latest advancements in interventional radiology techniques for pelvic conditions affecting women including adenomyosis, abdominal wall endometriosis and uterine leiomyoma. Extraperitoneal endometriosis involving the abdominal wall may be treated by percutaneous thermal ablation, such as cryoablation, whereas uterine leiomyoma and adenomyosis can be managed either using percutaneous thermal ablation or using uterine artery embolization. Continued research and development in interventional radiology will further enhance the minimally-invasive interventions available for women's health, improving outcomes and quality of life for this large patient population of women.

Expression of HIF-1α, Ki67, SMA and E-cadherin in endometriosis, endometrial and ovarian carcinoma

INTRODUCTION

Endometriosis is a benign gynecological condition that shares many characteristics with cancer cells, including immune evasion, survival, adhesion, invasion, and angiogenesis. The simultaneous investigation of tissue hypoxia, EMT, and proliferative index in endometriosis, endometrial, and ovarian carcinomas may provide new insight into the evolution and progression of gynecological neoplasms.

Innovative Ultrasound Criteria for the Diagnosis of Adenomyosis and Correlation with Symptoms: A Retrospective Re-Evaluation

The 2022 Delphi revision of the MUSA (Morphological Uterus Sonographic Assessment) criteria for the ultrasound diagnosis of adenomyosis divides the ultrasound signs for diagnosis into direct and indirect ones, considering the presence of at least one direct sign as a mandatory criterion. This study aimed to reclassify the patients referred to the Pelvic Pain specialist outpatient clinic of the Gynecological Clinic of Udine according to the new criteria, evaluating the number of overdiagnoses and the possible correlation between the direct and indirect signs and the patients' symptoms. 62 patients affected by adenomyosis were retrospectively recruited. The patients were then re-evaluated by ultrasound and clinically. At least one direct sign of adenomyosis was found in 52 patients, while 16% of the population examined did not present any. There was no statistically significant difference between patients presenting direct signs and those presenting none for the symptoms considered. According to the new criteria, 16% of the patients examined were not affected by adenomyosis; applying the new consensus to symptomatic patients could increase false negatives. In a population of symptomatic patients, the diagnosis of adenomyosis is still highly probable even without direct ultrasound signs, given the clinical symptoms and having ruled out other causes of such symptoms.

Effects of different treatment methods on clinical efficacy and fertility outcomes of patients with adenomyosis

OBJECTIVE

This trial was to investigate the effect of different treatment methods on the clinical efficacy and fertility outcome of patients with adenomyosis.

METHODS

In total, 140 patients with adenomyosis were evenly and randomly allocated into group A (laparoscopic surgery), group B (laparoscopic surgery combined with gonadotropin-releasing hormone analogs [GnRH-a]), group C (ultrasound-guided percutaneous radiofrequency ablation), and group D (ultrasound-guided percutaneous radiofrequency ablation combined with GnRH-a). On the 3rd day after surgery, patients in group B and group D were subcutaneously injected with GnRH-a (Leuprorelin Acetate SR for Injection) at 3.75 mg/time, once every 4 weeks, for a total of 3 months. The therapeutic effects of the 4 groups were compared, including menstrual volume, dysmenorrhea score, uterine volume, clinical efficacy, luteinizing hormone (LH), estradiol (E2), and follicle-stimulating hormone (FSH) levels, CA125 levels, recurrence, pregnancy status, and pregnancy outcomes.

RESULTS

After treatment, the menstrual volume of 4 groups was lowered, dysmenorrhea, Visual Analog Scale (VAS) score, LH, FSH, E2, and CA125 levels were reduced, and uterine volume was decreased. The menstrual volume, VAS score, levels of LH, FSH, E2, and CA125, and uterine volume were reduced in groups B, C, and D compared with group A, and the decrease was more significant in group D. The total effective rate of group D was 100.00%, which was higher than that of group A (71.43%), group B (80.00%), and group C (82.86%). After one year of drug withdrawal, the recurrence of hypermenorrhea, dysmenorrhea, uterine enlargement, and excessive CA125 in group D was significantly lower than that in groups A, B and C, and the recurrence in groups B and C was significantly lower than that in group A (P < 0.05). Compared with groups A, B, and C, group D had a higher pregnancy rate, natural pregnancy rate, and lower in vitro fertilization-embryo transfer rate (P < 0.05), but showed no significant difference in pregnancy outcomes.

CONCLUSION

Ultrasound-guided percutaneous radiofrequency ablation combined with Leuprorelin Acetate is effective in the treatment of adenomyosis, which can effectively relieve clinical symptoms, protect postoperative ovarian function, reduce recurrence rate, alleviate pain, and improve quality of life.

Association of normalization of postoperative carbohydrate antigen 125 levels with treatment failure following uterine artery embolization for adenomyosis

OBJECTIVE

To investigate the association between carbohydrate antigen 125 (CA125) level and adenomyosis treatment failure (TF) after uterine artery embolization (UAE).

METHODS

We evaluated 224 patients with symptomatic adenomyosis who underwent UAE between January 2016 and December 2020. Improvements in dysmenorrhea and menorrhagia were assessed on the basis of symptom relief criteria. The factors associated with TF were investigated using a multivariate logistic regression model. Patients were analyzed for preoperative CA125 levels, postoperative CA125 levels, and the normalization of postoperative CA125 levels. Long-term symptom relief and quality of life after UAE were compared between the groups.

RESULTS

During the 24-month follow-up, 50 patients (22.3%) experienced TF. Compared to patients in the non-TF group, those in the TF group had significantly higher preoperative and postoperative CA125 levels (p < 0.05). Multivariate analysis revealed that failure to normalize postoperative CA125 levels was independently associated with an increased risk of TF (34.7% vs. 8.5%, p < 0.001; hazard ratio 3.953, 95% confidence interval 1.567-9.973, p = 0.004). After a 3-month follow-up period, patients who normalized their CA125 levels were more likely to achieve complete necrosis on magnetic resonance imaging than those who did not (82.1% vs. 56.8%, p < 0.001). Normalization of postoperative CA125 levels was significantly associated with fewer symptoms and better quality of life 12 months after UAE (p < 0.05).

CONCLUSIONS

Following UAE, normalization of postoperative CA125 levels, rather than absolute values, was the strongest predictive marker of TF.

Diagnostic accuracy study of sonography in adenomyosis: A study of current practice

OBJECTIVES

To estimate diagnostic accuracy of sonography in the diagnosis of adenomyosis in current practice when compared to pathology as a "gold standard".

METHODS

This diagnosis accuracy study was observational and retrospective, including women managed by hysterectomy for benign pathology from January 2015 to November 2018. Preoperative pelvic sonography reports were collected, including details on diagnosis criteria for adenomyosis. Sonographic findings were compared to pathological results of the hysterectomy specimens.

RESULTS

Our study initially concerned 510 women; 242 of them had adenomyosis confirmed by a pathological examination. The pathological prevalence of adenomyosis was 47.4% in this study. A preoperative sonography was available for 89.4% of the 242 women, with a suspicion of adenomyosis in 32.7% of them. In this study, Sensitivity is 52%, Specificity 85%, Positive Predictive Value (PPV) 77%, Negative Predictive Value (NPV) 86% and Accuracy 38,1%.

CONCLUSIONS

Pelvic sonography is the most common non-invasive examination used in gynecology. It is also the first recommended examination for the diagnosis of adenomyosis because of its acceptability and its cost, even if the diagnosis performances are moderate. However, these performances are comparable to MRI (Magnetic Resonance Imaging) performances. The use of a standardized sonographic classification could improve and harmonize the diagnosis of adenomyosis.

Exophytic Subserosal Uterine Adenomyomatous Polyp Mimicking Malignancy: A Case Report

The epidemiological profile of adenomyosis has drastically changed in recent years due to advancements in imaging techniques. Even though adenomyosis is not uncommon in women of childbearing age, we present an intriguing case of a 30-year-old woman with long-standing progressive dysmenorrhea and infertility who had a posterior wall exophytic adenomyomatous polyp with full-thickness pseudo-invasion out of the uterine serosa into the right ovarian endometriotic cyst, mimicking malignancy. After surgical excision, the patient spontaneously conceived and delivered a live-term baby, soon after which she experienced an early recurrence. Clinicians must be aware of the distinctive features of different subtypes of adenomyosis to plan treatment and avoid invasive surgery.

Superinfection of Rectovaginal Endometriosis: Case Report and Review of the Literature

BACKGROUND

A peculiar complication of endometriosis is a superinfection. However, the superinfection of extra-ovarian endometriosis is anecdotal, and only a few cases have been described. We wanted to present the first cases of the superinfection of rectovaginal endometriosis and to perform a literature review of the superinfection of extra-ovarian endometriosis.

METHODS

We present a case of a 24-year-old woman who was referred to our Pelvic Floor Unit for rectal-perineal pain, dyspareunia, and recurrent episodes of dense purulent vaginal discharge for one year, in which the superinfection of rectovaginal endometriosis was diagnosed. Moreover, we performed a systematic search of the literature indexed on PubMed up to 31 January 2023.

RESULTS

Laparoscopic drainage was successful in managing this condition. In the literature, clinical presentation and instrumental and microbiological findings are very heterogeneous. However, the gold standard of management is represented by surgical or percutaneous drainage.

CONCLUSIONS

In the case of a pelvic abscess, the superinfection of endometriosis lesions should be suspected, and this can represent the onset symptom of endometriosis. Ultrasonography may show nodular or flat hypoechoic lesions with hyperechoic debris and peripheral positive color/power Doppler intensities. The goal of management is to drain the abscess, either percutaneously or via traditional surgery, followed by proper hormonal therapy to reduce recurrence.

Uterine Transcriptome: Understanding Physiology and Disease Processes

In recent years, transcriptomics has enabled us to gain a deeper understanding of fundamental reproductive physiology, including the menstrual cycle, through a more precise molecular analysis. The endometrial mRNA transcript levels fluctuate during the normal menstrual cycle, indicating changes in the relative recruitment and abundance of inflammatory cells, as well as changes in the receptivity and remodeling of the endometrium. In addition to providing a more comprehensive understanding of the molecular underpinnings of pathological gynecological conditions such as endometriosis, leiomyomas, and adenomyosis through RNA sequencing, this has allowed researchers to create transcriptome profiles during both normal menstrual cycles and pathological gynecological conditions. Such insights could potentially lead to more targeted and personalized therapies for benign gynecological conditions. Here, we provide an overview of recent advances in transcriptome analysis of normal and pathological endometrium.

Endometrial microbiota in women with and without adenomyosis: A pilot study

Introduction

The endometrial microbiota plays an essential role in the health of the female reproductive system. However, the interactions between the microbes in the endometrium and their effects on adenomyosis remain obscure.

Materials and methods

We profile endometrial samples from 38 women with (n=21) or without (n=17) adenomyosis to characterize the composition of the microbial community and its potential function in adenomyosis using 5R 16S rRNA gene sequencing.

Results

The microbiota profiles of patients with adenomyosis were different from the control group without adenomyosis. Furthermore, analysis identified Lactobacillus zeae, Burkholderia cepacia, Weissella confusa, Prevotella copri, and Citrobacter freundii as potential biomarkers for adenomyosis. In addition, Citrobacter freundii, Prevotella copri, and Burkholderia cepacia had the most significant diagnostic value for adenomyosis. PICRUSt results identified 30 differentially regulated pathways between the two groups of patients. In particular, we found that protein export, glycolysis/gluconeogenesis, alanine, aspartate, and glutamate metabolism were upregulated in adenomyosis. Our results clarify the relationship between the endometrial microbiota and adenomyosis.

Discussion

The endometrial microbiota of adenomyosis exhibits a unique structure and Citrobacter freundii, Prevotella copri, and Burkholderia cepacia were identified as potential pathogenic microorganisms associated with adenomyosis. Our findings suggest that changes in the endometrial microbiota of patients with adenomyosis are of potential value for determining the occurrence, progression, early of diagnosis, and treatment oadenomyosis.

Comparison of high-intensity focused ultrasound for the treatment of internal and external adenomyosis based on magnetic resonance imaging classification

OBJECTIVE

To compare the safety and efficacy of high-intensity focused ultrasound (HIFU) treatment for patients with internal or external adenomyosis based on magnetic resonance imaging (MRI) classification.

MATERIALS AND METHODS

A total of 238 patients with internal adenomyosis and 167 patients with external adenomyosis who received HIFU treatment were enrolled. HIFU treatment results and adverse effects between patients with internal and external adenomyosis were compared.

RESULTS

The treatment time and sonication time for patients with external adenomyosis were significantly longer than that for patients with internal adenomyosis. The total energy used and EEF for patients with external adenomyosis were higher than that for patients with internal adenomyosis (p < 0.05). The pre-HIFU median dysmenorrhea score in patients with internal or external adenomyosis was 5 or 8 points, the median score decreased to 1 or 3 points in these two groups at 18-month post-HIFU (p < 0.05). The relief rate of dysmenorrhea was 79.5% in patients with internal adenomyosis, and it was 80.8% in patients with external adenomyosis. The pre-HIFU median menorrhagia score in patients with internal or external adenomyosis was 4 or 3 points, the median score decreased to 1 point in both groups at 18-month post-HIFU with a relief rate of 86.2% and 77.1%, respectively (p = 0.030). No serious complication occurred in any of these patients.

CONCLUSIONS

HIFU is a safe and effective treatment either for patients with internal adenomyosis or external adenomyosis. It seemed that internal adenomyosis is easier to be treated with HIFU and with a higher relief rate of menorrhagia than external adenomyosis.

Comparison of pregnancy outcomes in infertile patients with different types of adenomyosis treated with high-intensity focused ultrasound

OBJECTIVE

This study assessed the improvement of symptoms and pregnancy outcomes in infertile patients with various types of adenomyosis who were treated with high-intensity focused ultrasound (HIFU).

MATERIALS AND METHODS

Between October 2017 and January 2022, 129 infertile patients with adenomyosis who wished to conceive were treated with HIFU. Based on the relationship between the adenomyotic lesion, the endometrium, and the subserosa of the uterus on magnetic resonance imaging, the adenomyotic lesions were divided into internal, external, intramural, and full-thickness types. Menstruation pain score, menstruation blood volume score, anti-Müllerian hormone (AMH) levels, reproductive results, pregnancy and delivery complications, and other clinical variables were compared among these four groups.

RESULTS

Patients with external adenomyosis had the greatest menstrual distress, whereas patients with internal adenomyosis had the greatest menstrual blood volume. Dysmenorrhea and heavy menstruation were significantly improved after HIFU treatment in all groups. AMH levels were not significantly different before and six months after HIFU. Of the 129 patients, 50 (38.7%) became pregnant after HIFU, and patients with internal adenomyosis had the highest pregnancy rate. Patients with adenomyotic lesions located in the posterior wall of the uterus had a higher pregnancy rate than those with lesions located in the fundus of the uterus.

CONCLUSIONS

The classification of adenomyosis is closely related to distinctions in clinical symptoms and pregnancy outcomes. Infertile patients with different types of adenomyosis could be effectively treated with HIFU. HIFU can be considered as an option for infertile patients with adenomyosis who want to maintain their fertility.

Pituitary suppression with GnRH agonists before ART may be insufficient to treat women with severe adenomyosis

RESEARCH QUESTION

Does aromatase inhibitor improve IVF outcomes by reducing local oestrogen production in patients with adenomyosis undergoing long-term gonadotrophin-releasing hormone agonist (GnRHa) treatment?

DESIGN

Four patients with severe adenomyosis who failed to improve after long-term treatment (≥3 months) with depot GnRHa received treatment with an aromatase inhibitor for 21 days. Blood oestradiol concentrations were monitored after GnRHa treatment both before and after treatment with an aromatase inhibitor. Women received a transfer of IVF autologous or donor oocytes. Pregnancy and ongoing pregnancy rates were the primary outcomes. Blood oestradiol concentration after treatment with an aromatase inhibitor was a secondary outcome.

RESULTS

Patients with severe adenomyosis presented with hyperestrogenism due to local production from the lesions even after long-term treatment with GnRHa. Treatment with an aromatase inhibitor reduced hyperestrogenism and improved clinical outcomes in adenomyosis patients who have experienced previous embryo transfer failures.

CONCLUSION

Women with severe adenomyosis would benefit from letrozole or a combination of GnRHa plus letrozole before receipt of treatment with assisted reproductive technology. For women with severe adenomyosis, GnRHa treatment alone may be insufficient to suppress oestrogen production by adenomyotic lesions. Thus, it should be mandatory to test for oestradiol concentrations in patients with severe adenomyosis who have received long-term GnRHa treatment. Also, GnRHa may not always be the sole strategy for medical management of adenomyotic lesions. Letrozole is safe and can improve IVF outcomes for patients with adenomyosis.

Transcervical radiofrequency ablation of focal adenomyosis: pilot results

Objective: Adenomyosis is a common gynecological disease, which occurs in women in reproductive age and is characterized by the presence of endometrial glands and stroma within the myometrium. Abnormal uterine bleeding, pelvic pain as well as infertility can be associated with adenomyosis. There are two main types of adenomyosis: diffuse and focal. Previously, adenomyosis was diagnosed only upon histopathological examination after hysterectomy and/or adenomyomectomy. However, the development of imagining techniques such as transvaginal ultrasound and magnetic resonance imaging enables the diagnosis of adenomyosis (diffuse and focal) without any surgical intervention. When medical therapy is contraindicated or ineffective, or if patients have a fertility desire, a surgical treatment may be necessary.Methods: In this study, a total of 13 patients with 16 areas of focal adenomyosis were treated. All patients provided their informed consent to undergo transcervical adenomyosis ablation treatment with the Sonata System, aware that the safety and effectiveness of transcervical radiofrequency (RF) ablation for the treatment of adenomyosis has not been established. Follow-up was performed six months after Sonata treatment.Results: The positive results relating to the improvement of symptoms and reduction of adenomyosis lesion size were observed in our study.Conclusion: Transcervical RF ablation with the Sonata System may be a promising therapeutic alternative method to conventional procedures such as hysterectomy for the treatment of focal adenomyosis, disease which has limited therapeutic approach, and may enable a minimally invasive, uterine preserving option.

Uterine Anteroposterior Diameter Measured by Transvaginal Sonography is a Predictor for Dysmenorrhea in Patients With and Without Endometriosis: A Pilot Study

PURPOSE

The aim of this study was to determine the correlation between uterine diameters and menstrual abdominal pain intensity in patients with and without endometriosis (EM), and the independent influence of EM on the pain intensity.

METHODS

Uterine diameters and the diagnosis of adenomyosis were ascertained by transvaginal ultrasonography (TVS). Menstrual abdominal pain intensity was estimated by visual analog scale (VAS). Linear regression was used to figure out the impact of uterine diameters and EM on the VAS scores. Logistic regression was used to calculate the correlation between uterine diameters and the diagnosis of adenomyosis. The cutoff values of uterine anteroposterior diameter (AD) to predict dysmenorrhea (VAS ≥ 4) and the diagnosis of adenomyosis were determined by receiver operating characteristic curves.

RESULTS

There were 220 patients with and 233 patients without EM included. Uterine AD independently correlated with the VAS scores in patients with (B = .230, P = .000) and without (B = .203, P = .000) EM. A uterine AD of 39.5 mm predicted dysmenorrhea in both groups. The presence of EM increased the VAS scores by 1.151 points when controlling for uterine diameters. Uterine AD also independently correlated with the diagnosis of adenomyosis under TVS in patients with (OR = 1.212, 95% CI = 1.130-1.301; P = .000) and without (OR = 1.192, 95% CI = 1.123-1.263; P = .000) EM. A uterine AD of 38.5 and 39.5 mm predicted the diagnosis of adenomyosis under TVS in patients with and without EM, respectively.

CONCLUSIONS

Increased uterine AD, which is probably ascribed to adenomyosis, plays an important role in augmented menstrual abdominal pain intensity. Meanwhile, the presence of EM reinforces the pain.

An innovative surgical approach: suture fixation of the levonorgestrel-releasing intrauterine system in the treatment of adenomyosis

Background

Placement of a levonorgestrel-releasing intrauterine system (LNG-IUS) is an effective treatment for adenomyosis, especially for patients who have severe dysmenorrhea symptoms but a strong desire to preserve fertility. Nonetheless, for patients with adenomyosis accompanied by an enlarged uterus, expulsion of the ring is a troublesome problem. In this study, we sewed and fixed the LNG-IUS in the uterus, which provides a good solution to this problem.

Methods

In this prospective case series approved by the Ethics Committee of Hangzhou Women’s Hospital, 12 patients with adenomyosis were successfully enrolled after providing informed consent, and all patients underwent long-term postoperative follow-up.

Results

Twelve patients with adenomyosis underwent suture fixation with an LNG-IUS, and during the long-term postoperative follow-up, every patient experienced complete remission of their symptoms: a significant decrease in menstrual flow, relief of dysmenorrhea, and improvement in quality of life. Only one person reported expulsion a year later.

Conclusion

In patients with adenomyosis suffering from dysmenorrhea or excessive menstrual blood loss, suture fixation of an LNG-IUS using the hysteroscopic cold knife surgery system is a minimally invasive and effective alternative treatment for adenomyosis and decreases the risk of LNG-IUS expulsion.

Altered Expression of Interleukin-18 System mRNA at the Level of Endometrial Myometrial Interface in Women with Adenomyosis

Adenomyosis is a uterine pathology characterized by a deep invasion of endometrial glands and stroma, disrupting the endometrial−myometrial interface (EMI). Interleukin-18 (IL-18) system is a dominant cytokine involved in the menstrual cycle of human endometrium. IL-18 may play a defensive role against maternal immune response in the uterine cavity. The present study was designed to determine IL-18-mediated immune response at the level of EMI. We uncovered that mRNA of IL-18 system, including IL-18, IL-18 receptor (IL-18R), and its antagonist, IL-18 binding protein (IL-18BP), expressed in eutopic, ectopic endometrium, and corresponding myometrium in patients with adenomyosis. IL-18 system was demonstrated in paired tissue samples by immunochemistry and immunofluorescence study. According to RT-PCR with CT value quantification and 2−∆∆Ct method, a significant down-regulation of IL-18BP in corresponding myometrium in comparison to eutopic endometrium (p < 0.05) indicates that the IL-18 system acts as a local immune modulator at the level of EMI and regulating cytokine networks in the pathogenesis of adenomyosis. Furthermore, an increased IL-18 antagonist to agonist ratio was noted in ectopic endometrium compared with corresponding myometrium. We suggest that altered IL-18 system expression contributes to immunological dysfunction and junctional zone disturbance in women with adenomyosis.

Factors influencing treatment decisions in HIFU treatment of adenomyosis: A retrospective study

Objective

To explore the influencing factors of decision-making in patients with adenomyosis, who are receiving high-intensity focused ultrasound (HIFU) treatment.

Methods

A total of 776 patients with adenomyosis were enrolled into HIFU group (241 cases) and hysterectomy group (535 cases) according to the treatment methods. The general data, clinical symptoms, marital and childbearing history, and economic status were compared between the two groups, and factors with P < 0.05 were introduced into multivariate logistic regression analysis to determine the determinants of patients choosing HIFU.

Results

The average age of the patients in the HIFU group was 39.1 ± 5.2 years, which was lower than that in the hysterectomy group, which was 45.1 ± 3.9 years (P < 0.05). The basic medical insurance for urban workers in the HIFU group was more than the hysterectomy group (P < 0.05). 95.9% of the hysterectomy group had no desire to have children, compared to 60.6% of the HIFU group, the difference was significant (P < 0.05). The treatment costs of HIFU group were significantly lower than that of hysterectomy group (P < 0.05). The main symptoms of the two groups were dysmenorrhea, menorrhagia, and secondary anemia. The results of multivariate logistic regression analysis showed that 31–40 years old, fertility desire, dysmenorrhea, menorrhagia, anemia and dizziness and fatigue were the influencing factors for the decision-making of HIFU for patients with adenomyosis.

Conclusion

31–40 years old, fertility desire, dysmenorrhea, menorrhagia, anemia and dizziness and fatigue were the influencing factors for patients to choose HIFU treatment. HIFU therapy has emerged as a new option for patients with adenomyosis as an alternative to hysterectomy.

Brain Morphological and Functional Changes in Adenomyosis with Pain: A Resting State Functional Magnetic Resonance Imaging Study

The absence of clinically objective methods to evaluate adenomyosis-associated pain and the poor understanding of its pathophysiology lead to treatment limitations. We conducted a resting-state functional magnetic resonance imaging study with 49 patients with pain-related adenomyosis and 30 pain-free controls to investigate brain morphological alterations and regional dysfunctions in patients with pain-related adenomyosis. These patients had significantly higher scores for anxiety and depression than the control group (p < 0.05). They also had a lower gray matter volume (GMV) in the bilateral insula, left angular gyrus, precuneus, left inferior temporal gyrus, and left postcentral gyrus (p < 0.05, AlphaSim corrected). Similarly, decreased voxel-mirrored homotopic connectivity was observed in the bilateral insula, posterior cingulate cortex, middle frontal gyrus, and postcentral gyrus in the adenomyosis patient group (p < 0.05, AlphaSim corrected). Regional homogeneity showed significant differences mainly in the bilateral cerebellum, left inferior frontal gyrus, medial prefrontal cortex, and posterior cingulate gyrus. Correlation analysis showed that the degree of depression in patients with adenomyosis was negatively correlated with the GMV of the left angular gyrus. The results show that these patients exhibited changes in multiple brain regions associated with pain as well as emotion perception and processing.

Acute recurrent cerebral infarction caused by moyamoya disease complicated with adenomyosis: A case report

BACKGROUND

Moyamoya disease is essentially an ischemic cerebrovascular disease. Here, we describe a case of acute recurrent cerebral infarction caused by moyamoya disease with concurrent adenomyosis which, to our knowledge, is the first in the literature. A literature review is also presented.

CASE SUMMARY

A 38-year-old female presented to the Research and Treatment Center of Moyamoya Disease in our hospital with "left limb weakness" as the main symptom. She was diagnosed with acute cerebral infarction and moyamoya disease through magnetic resonance imaging and digital subtraction angiography. Prior to this, she had experienced a prolonged menstrual period of one-month duration. This was investigated and adenomyosis was diagnosed. After passing the acute cerebral infarction phase, the patient underwent surgery for adenomyosis followed by combined cerebral revascularization. During the postoperative follow-up, improvements of the perfusion imaging stage and modified Rankin Scale were observed. A review of the literature showed only 16 reported cases of gynecological diseases complicated with stroke. The clinical characteristics, pathogenesis, therapeutic effects, and long-term prognosis of these cases have been studied and discussed.

CONCLUSION

In patients with moyamoya disease, early management of gynecological-related bleeding disorders is essential to prevent the complications of cerebral events.

Progesterone Actions and Resistance in Gynecological Disorders

Estrogen and progesterone and their signaling mechanisms are tightly regulated to maintain a normal menstrual cycle and to support a successful pregnancy. The imbalance of estrogen and progesterone disrupts their complex regulatory mechanisms, leading to estrogen dominance and progesterone resistance. Gynecological diseases are heavily associated with dysregulated steroid hormones and can induce chronic pelvic pain, dysmenorrhea, dyspareunia, heavy bleeding, and infertility, which substantially impact the quality of women's lives. Because the menstrual cycle repeatably occurs during reproductive ages with dynamic changes and remodeling of reproductive-related tissues, these alterations can accumulate and induce chronic and recurrent conditions. This review focuses on faulty progesterone signaling mechanisms and cellular responses to progesterone in endometriosis, adenomyosis, leiomyoma (uterine fibroids), polycystic ovary syndrome (PCOS), and endometrial hyperplasia. We also summarize the association with gene mutations and steroid hormone regulation in disease progression as well as current hormonal therapies and the clinical consequences of progesterone resistance.

Anti-Mullerian Hormone (AMH) and adenomyosis: Mini-review of literature of the last 5 years

INTRODUCTION

Adenomyosis is a form of endometriosis characterized by the presence of endometrial tissue in the myometrium. The correlation between anti-Mullerian hormone (AMH) expression and adenomyosis is unclear. Few studies investigated this possible correlation with promising results. The aim of this mini-review is to illustrate the potential prognostic and therapeutic role of AMH in adenomyosis.

MATERIALS AND METHODS

A study protocol was completed conforming to the Preferred Reporting Items for Reviews and Meta-Analyses (PRISMA) guidelines for systematic reviews. We performed an electronic databases search from each database's inception from August 2017 to August 2022 for full-text articles and published abstracts. For database searches, the following main keywords were the following text words: "adenomyosis" or "uterine endometriosis" [Mesh] AND "AMH" or "anti-mullerian hormone".

RESULTS

From the literature search, 8 abstracts of studies were retrieved and independently screened for inclusion by three authors. It was found that the most common therapeutic strategies (such as adenomyomectomy and high-intensity focused ultrasound (HIFU) do not alter AMH levels. Moreover, a higher expression of the AMH receptor II was observed in adenomyotic tissue, hence a possible therapeutic use of AMH was hypothesized.

CONCLUSION

The available evidence shows an unclear relationship between adenomyosis and AMH. Probably, women with adenomyosis have lower levels of AMH and the surgical treatment (adenomyomectomy, HIFU) does not alter this characteristic, therefore in all of them, ovarian function is not influenced.
