Abstract
OBJECTIVE This study aimed to establish the first-ever MRI classification of uterosacral ligament (USL) involvement in deep infiltrating endometriosis (DIE), based on reliable preoperative MRI features correlated with positive predictive values (PPVs) determined through histopathological analysis. METHODS Twenty-two women underwent surgery with histopathology due to symptoms highly suggestive of endometriosis. The 22 preoperative MRIs were analysed retrospectively, blinded to histopathology, and a classification of the preoperative aspect of USLs linked to PPVs was designed. RESULTS According to their aspects, 6 radiological types of USL were identified. The "L-category" corresponded to linear types with regular or irregular margins, including types 1, 2, 3A, and 3B. The "N-category" corresponded to haemorrhagic or nodular types, including types 4, 5A, 5B, and 6. For the L-category, PPVs ranged from 75% to 88%, depending on the USL radiological type. For the N-category, PPVs were 100% for each type. In women with endometriosis symptoms, MRI underestimated USL involvement, especially for type 1. Among the 6 uteri with lateral deviation, only one false-positive result concerning the stretched USL was induced. CONCLUSIONS In women with endometriosis symptoms, our MRI classification identified 2 USL categories, corresponding to 2 kinds of PPV; in these symptomatic patients, a normal MRI does not rule out a DIE diagnosis. ADVANCES IN KNOWLEDGE Our MRI classification of USL involvement in endometriosis may be used as a non-invasive staging of the disease, making it much clearer for clinicians and patients. Hence, we are able to propose a suitable diagnostic and therapeutic procedure for each radiological type.

Abstract
BACKGROUND Endometriosis (EM) is a complex benign gynecological disease, but it has malignant biological behavior and can invade any part of the body. Clinical manifestations include pelvic pain, dysmenorrhea, infertility, pelvic nodules, and masses. Our previous study successfully detected circulating endometrial cells (CECs) in the peripheral blood of patients with EM. The purpose of this study is to overcome the limitation of cell size in the previous microfluidic chip method, to further accurately capture CECs, understand the characteristics of these cells, and explore the relationship between CECs and the clinical course characteristics of patients with EM. METHODS Human peripheral venous blood used to detect CECs and circulating vascular endothelial cells (CVECs) was taken from EM patients (n = 34) hospitalized in the Peking University People's Hospital. We use the subtraction enrichment and immunostaining fluorescence in situ hybridization (SE-iFISH) method to exclude the interference of red blood cells, white blood cells, and CVECs, so as to accurately capture the CECs in the peripheral blood of patients with EM. Then we clarify the size and ploidy number of chromosome 8 of CECs, and a second grouping of patients was performed based on clinical characteristics to determine the relationship between CECs and clinical course characteristics. RESULTS The peripheral blood of 34 EM patients and 12 non-EM patients was evaluated by SE-iFISH. Overall, 34 eligible EM patients were enrolled. The results showed that the detection rates of CECs were 58.8% in EM patients and 16.7% in the control group. However, after classification according to clinical characteristics, more CECs could be detected in the peripheral blood of patients with rapidly progressive EM, with a detection rate of 94.4% (17/18). In total, 63.5% (40/63) of these cells were small cells with diameters below 5 μm, and 44.4% (28/63) were aneuploid cells. No significant association was found between the number of CECs and EM stage. CONCLUSION The number and characteristics of CECs are related to the clinical course characteristics of patients with EM, such as pain and changes in lesion size, and may be used as biomarkers for personalized treatment and management of EM in the future.

Abstract
INTRODUCTION Endometriosis is a gynecological pathology defined by the presence and abnormal development of endometrial tissue outside the uterine cavity. Our objective was to draw up an epidemiological profile and to describe the anatomical clinical forms of endometriosis in Dakar. PATIENTS AND METHODS This is a retrospective study of all cases of external and internal endometriosis diagnosed in an anatomy and pathology laboratory in Dakar over a period of twenty (20) years. The study parameters were collected from anonymous data sheets. Data entry and analysis were performed using version 22 of the EPI INFO and SPSS software. RESULTS Our study involved 104 female patients. The mean age was 47.3±10.0. Among the patients with an adenomyosis condition, the mean age was 49.8 years. Patients with an external endometriosis condition had a mean age of 37.6 years. The location of the endometriosis was statistically correlated with the age of patients and with parity. Anatomically and pathologically, the surgical specimen 89.4% (n=93) was the main type of sampling that was found. The uterine body was the main location of the pathology, with 78.9% (n=82), followed by the umbilical location with 9.6% (n=10). Leiomyomas 44.07% (n=26) were the main associated lesions. CONCLUSION Endometriosis is a gynecological pathology that is unfortunately not well known, and which is under diagnosed in Senegal.

Abstract
OBJECTIVE To determine the diagnostic test accuracy of transvaginal ultrasound (TVS) using a standardized technique for the diagnosis of deep endometriosis (DE) of the uterosacral ligaments (USLs) and adjacent torus uterinus (TU). METHODS This was a prospective diagnostic test accuracy study conducted at the McMaster University Medical Center Tertiary Endometriosis Clinic, Hamilton, ON, Canada. Consecutive participants were enrolled if they successfully underwent TVS and surgery by our team from 10 August 2020 to 31 October 2021. The index test was TVS using a standardized posterior approach performed and interpreted by an expert sonologist. The reference standard included direct surgical visualization on laparoscopy by the same person who performed and interpreted the ultrasound scans. Accuracy, sensitivity, specificity, positive and negative predictive values (PPV and NPV) and positive and negative likelihood ratios were calculated for the TVS posterior approach for each location using the reference standard. RESULTS There were 54 consecutive participants included upon completion of laparoscopy and histological assessment. The prevalence of DE for the left USL, right USL and TU was 42.6%, 22.2% and 14.8%, respectively. Based on surgical visualization as the reference standard, TVS demonstrated an accuracy of 92.6% (95% CI, 82.1-97.9%), sensitivity of 82.6% (95% CI, 61.2-95.1%), specificity of 100% (95% CI, 88.8-100%), PPV of 100% and NPV of 88.6% (95% CI, 76.1-95.0%) for diagnosing DE in the left USL. For DE of the right USL, TVS demonstrated an accuracy of 94.4% (95% CI, 84.6-98.8%), sensitivity of 75.0% (95% CI, 42.8-94.5%), specificity of 100% (95% CI, 91.6-100%), PPV of 100% and NPV of 93.3% (95% CI, 84.0-97.4%). For DE of the TU, TVS demonstrated an accuracy of 100% (95% CI, 93.4-100%), sensitivity of 100% (95% CI, 63.1-100%), specificity of 100% (95% CI, 92.3-100%), PPV of 100% and NPV of 100%. CONCLUSIONS We observed high diagnostic test accuracy of the evaluated standardized TVS technique for assessing DE of the USLs and TU. Further studies evaluating this technique should be performed, particularly with less experienced observers, before considering this technique as the standard approach. © 2023 The Authors.

Abstract
Endometriosis, a systemic ailment, profoundly affects various aspects of life, often eluding detection for over a decade. This leads to enduring issues such as chronic pain, infertility, emotional strain, and potential organ dysfunction. The prolonged absence of diagnosis can contribute to unexplained obstetric challenges and fertility issues, necessitating costly and emotionally taxing treatments. While biopsy remains the gold standard for diagnosis, emerging noninvasive screening methods are gaining prominence. These tests can indicate endometriosis in cases of unexplained infertility, offering valuable insights to patients and physicians managing both obstetric and non-obstetric conditions. In a retrospective cross-sectional study involving 215 patients aged 25 to 45 with unexplained infertility, diagnostic laparoscopy was performed after unsuccessful reproductive technology attempts. Pathology results revealed tissue abnormalities in 98.6% of patients, with 90.7% showing endometriosis, confirmed by the presence of endometrial-like glands and stroma. The study underscores the potential role of endometriosis in unexplained infertility cases. Although the study acknowledges selection bias, a higher than previously reported prevalence suggests evaluating endometriosis in patients who have not responded to previous reproductive interventions may be justified. Early detection holds significance due to associations with ovarian cancer, prolonged fertility drug use, pregnancy complications, and elevated post-delivery stroke risk.

Abstract
BACKGROUND The purpose of this systematic review and meta-analysis was to compile existing evidence on the significance of the NLR in predicting endometriosis in order to aid clinical decision-making and outcomes. METHODS We searched ProQuest, Web of Science, and PubMed for related studies published before January 2, 2023. Standardized mean difference (SMD) with a 95% confidence interval (CI) was reported for each outcome. Because a significant level of heterogeneity was found, we used the random-effects model to calculate pooled effects. We used Newcastle-Ottawa Scale (NOS) for quality assessment. RESULTS Overall, 18 article with were included in the analysis. A random-effect model revealed that patients with endometriosis had elevated levels of NLR compared to healthy controls (SMD = 0.79, 95% CI = 0.33 to 1.25, P < 0.001). Patients with endometriosis had elevated levels of NLR compared to those with other benign tumors (SMD = 0.85, 95% CI = 0.17 to 1.53, P = 0.014). In addition, NLR level of patients with stage III and IV endometriosis was not different from that of patients with stage I and II endometrioma (SMD = 0.30, 95% CI = -0.14 to 0.74, P = 0.18). However, NLR level was not different between endometriosis patients with and without peritoneal lesions (SMD = -0.12, 95% CI = -0.34to 0.10, P = 0.28), between patients with and without endometrioma (SMD = 0.20, 95% CI = -0.15 to 0.55, P = 0.26) and between endometriosis patients with and without deep lesions (SMD = 0.04, 95% CI = -0.20 to 0.28, P = 0.72). The pooled sensitivity of NLR was 0.67 (95% CI = 0.60-0.73), and the pooled specificity was 0.68 (95% CI, 0.62-0.73). CONCLUSIONS NLR might be utilized in clinics as a possible predictor to help clinicians diagnose endometriosis in affected women.

Abstract
Endometriosis is a common estrogen-dependent disorder wherein uterine lining tissue (endometrium) is found mainly in the pelvis where it causes inflammation, chronic pelvic pain, pain with intercourse and menses, and infertility. Recent evidence also supports a systemic inflammatory component that underlies associated co-morbidities, e.g., migraines and cardiovascular and autoimmune diseases. Genetics and environment contribute significantly to disease risk, and with the explosion of omics technologies, underlying mechanisms of symptoms are increasingly being elucidated, although novel and effective therapeutics for pain and infertility have lagged behind these advances. Moreover, there are stark disparities in diagnosis, access to care, and treatment among persons of color and transgender/nonbinary identity, socioeconomically disadvantaged populations, and adolescents, and a disturbing low awareness among health care providers, policymakers, and the lay public about endometriosis, which, if left undiagnosed and under-treated can lead to significant fibrosis, infertility, depression, and markedly diminished quality of life. This review summarizes endometriosis epidemiology, compelling evidence for its pathogenesis, mechanisms underlying its pathophysiology in the age of precision medicine, recent biomarker discovery, novel therapeutic approaches, and issues around reproductive justice for marginalized populations with this disorder spanning the past 100 years. As we enter the next revolution in health care and biomedical research, with rich molecular and clinical datasets, single-cell omics, and population-level data, endometriosis is well positioned to benefit from data-driven research leveraging computational and artificial intelligence approaches integrating data and predicting disease risk, diagnosis, response to medical and surgical therapies, and prognosis for recurrence.

Abstract
The actual prevalence of superficial endometriosis is not known. However, it is considered the most common subtype of endometriosis. The diagnosis of superficial endometriosis remains difficult. In fact, little is known about the ultrasound features of superficial endometriotic lesions. In this study, we aimed to describe the appearance of superficial endometriosis lesions at ultrasound examination, with laparoscopic and/or histologic correlation. This is a prospective study on a series of 52 women with clinical suspicion of pelvic endometriosis who underwent preoperative transvaginal ultrasound and received a confirmed diagnosis of superficial endometriosis via laparoscopy. Women with ultrasound or laparoscopic findings of deep endometriosis were not included. We observed that superficial endometriotic lesions may appear as a solitary lesions, multiple separate lesions, and cluster lesions. The lesions may exhibit the presence of hypoechogenic associated tissue, hyperechoic foci, and/or velamentous (filmy) adhesions. The lesion may be convex, protruding from the peritoneal surface, or it may appear as a concave defect in the peritoneum. Most lesions exhibited several features. We conclude that transvaginal ultrasound may be useful for diagnosing superficial endometriosis, as these lesions may exhibit different ultrasound features.

Abstract
BACKGROUND AND AIM A comprehensive understanding of endometriosis and its common gastrointestinal presentations are critical for gastroenterologists to ensure appropriate and timely screening and diagnosis. Endometriosis is a common inflammatory disease that frequently presents with gastrointestinal symptoms overlapping with irritable bowel syndrome (IBS) and other gastrointestinal disorders. Many endometriosis patients first present to a gastroenterologist or generalist, which may prolong the time to diagnosis and appropriate care. METHOD AND RESULTS This review describes the current literature on endometriosis presentation, overlap with gastrointestinal conditions, and standard diagnostic and treatment options for gastroenterologists to consider. For appropriate and swift treatment, gastroenterologists must consider an endometriosis diagnosis in females of menstruating age presenting with pain, bloating, altered stools, and non-gastrointestinal symptoms and refer patients for further evaluation.

[PMID: 36367580 PMCID: PMC9837004 DOI: 10.1007/s00404-022-06766-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Accepted: 08/19/2022] [Indexed: 11/13/2022]
Abstract
Gynecological ultrasonography plays a central role in the management of endometriosis. The rapid technical development as well as the currently increasing evidence for non-invasive diagnostic methods require an updated compilation of recommendations for the use of ultrasound in the management of endometriosis. The present work aims to highlight the accuracy of sonography for diagnosing and classifying endometriosis and will formulate the present list of key messages and recommendations. This paper aims to demonstrate the accuracy of TVS in the diagnosis and classification of endometriosis and to discuss the clinical applications and consequences of TVS findings for indication, surgical planning and assessment of associated risk factors. (1) Sophisticated ultrasound is the primary imaging modality recommended for suspected endometriosis. The examination procedure should be performed according to the IDEA Consensus. (2) Surgical intervention to confirm the diagnosis alone is not recommended. A preoperative imaging procedure with TVS and/or MRI is strongly recommended. (3) Ultrasound examination does not allow the definitive exclusion of endometriosis. (4) The examination is primarily transvaginal and should always be combined with a speculum and a bimanual examination. (5) Additional transabdominal ultrasonography may enhance the accuracy of the examination in case of extra pelvic disease, extensive findings or limited transvaginal access. (6) Sonographic assessment of both kidneys is mandatory when deep endometriosis (DE) and endometrioma are suspected. (7) Endometriomas are well defined by sonographic criteria. When evaluating the ovaries, the use of IOTA criteria is recommended. (8) The description of sonographic findings of deep endometriosis should be systematically recorded and performed using IDEA terminology. (9) Adenomyosis uteri has sonographically well-defined criteria (MUSA) that allow for detection with high sensitivity and specificity. MRI is not superior to differentiated skilled ultrasonography. (10) Classification of the extent of findings should be done according to the #Enzian classification. The current data situation proves the best possible prediction of the intraoperative situs of endometriosis (exclusive peritoneum) for the non-invasive application of the #Enzian classification. (11) Transvaginal sonographic examination by an experienced examiner is not inferior to MRI diagnostics regarding sensitivity and specificity in the prediction of the extent of deep endometriosis. (12) The major advantage of non-invasive imaging and classification of endometriosis is the differentiated planning or possible avoidance of surgical interventions. The recommendations represent the opinion of experts in the field of non-invasive and invasive diagnostics as well as therapy of endometriosis. They were developed with the participation of the following national and international societies: DEGUM, ÖGUM, SGUM, SEF, AGEM/DGGG, and EEL.

J Minim Invasive Gynecol 2022; 29:1339-1343. [PMID: 36154901 DOI: 10.1016/j.jmig.2022.09.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 09/16/2022] [Accepted: 09/19/2022] [Indexed: 12/14/2022]
Abstract
STUDY OBJECTIVE To assess the association between laparoscopic appearance of superficial endometriosis lesions, histopathology, and systemic hormone use. DESIGN Retrospective study. SETTING Tertiary care academic medical center. PATIENTS We identified 266 women who underwent laparoscopic surgery at an endometriosis center with excision of lesions consistent with possible superficial endometriosis between September 2015 and November 2018. INTERVENTIONS Appearance of the peritoneal lesions was confirmed with review of surgical videos and correlated with each pathology specimen. Lesions were dichotomized on positive or negative pathology assessment. All pathology-positive lesions were further dichotomized by hormone use within 1 month of surgery. MEASUREMENTS AND MAIN RESULTS A total of 841 lesions were biopsied from included subjects during the study period. Of those, 251 biopsies were negative, and 590 were positive for endometriosis on pathology assessment. Lesions had significantly higher odds of positive histology when they were red (odds ratio [OR], 1.70; 95% confidence interval [CI], 1.17-2.48), white (OR, 1.99; 95% CI, 1.47-2.70), blue/black (OR, 2.98; 95% CI, 2.00-4.44), or puckering (OR, 9.78; 95% CI, 2.46-38.91) in appearance. The following combined characteristics had significantly higher odds of positive histology: white and blue (OR, 5.98; 95% CI, 2.97-12.02), red and white (OR, 2.22; 95% CI, 1.38-3.56), red and blue (OR, 4.11; 95% CI, 1.83-9.24), and clear and white (OR, 8.77; 95% CI, 1.17-66.02). Among positive biopsies, those with hormone exposure were more likely to have clear lesions than those without hormone use (OR, 3.36; 95% CI, 1.54-7.34) and were 2.89 times more likely to have clear and white lesions (95% CI, 1.07-7.85). CONCLUSION Although lesions suspicious for endometriosis may have differing rates of positive pathology based on appearance, no lesion characteristic was able to exclude the possibility of endometriosis. In addition, hormone use may influence lesion appearance at the time of surgery, with clear lesions more prevalent. These data have implications for appropriate identification of endometriosis at the time of laparoscopy to ensure accurate diagnosis and complete treatment of disease.

Abstract
Current clinical staging/grading schemes of endometriosis show poor correlation with clinical symptoms and histopathological confirmation is only in half of the clinically suspected endometriosis. In this study, done over an 8-year period, several histological features were analysed including an attempt to grade the severity of endometriosis histologically based on the number of foci per low power field. The components in each focus, the phasing of the glands and stroma, the type of glands (endometrial type or undifferentiated type), and stromal features were all analysed. This study attempts to histologically grade endometriosis while relating it to the clinical manifestations and anatomical location. Eighty cases of endometriosis were included. Most common clinical presentation was cyclical pain (n = 62) and the most common anatomical location was adnexa (n = 50). Histologically, severe endometriosis (>3 foci) was seen in 37 cases. The components were mixed in 68 cases. Well-differentiated glandular pattern was typical (n = 54), while 6 cases had undifferentiated. Proliferative phase was seen in 38 cases. Fibrosis and inflammation were present in 29 and 42 cases, respectively. Significant vascular proliferation and plasma cell infiltrate was noted (n = 35). The severe grade was significantly associated with fibrosis (p = 0.03) and inflammation (p = 0.014). Endometriotic foci, unlike eutopic endometrium, shows significant plasma cell infiltrate and vascular proliferation.IMPACT STATEMENTWhat is already known on this subject? Endometriosis, a chronic inflammatory condition in reproductive age group women. The currently used clinical staging and grading systems show poor correlation with patient symptoms and treatment outcomes. Endometriosis with classical histopathological features pose no diagnostic difficulty, however, there is poor concordance with histopathology. Atypical endometriosis is proposed as potential precursor for endometriosis related neoplasms, however, it remains as a controversial entity.What do the results of this study add? The study identifies the uncommon histological patterns which may be encountered in biopsy samples from clinically identified endometriotic lesions. The recognition of these patterns will reduce clinico-pathological discrepancies. In keeping with the other grading systems, attempts at histological grading did not show any correlation with location or patient symptoms. Atypical features were seen only in two cases and was likely to be reactive in nature.What are the implications of these findings for clinical practice and/or further research? Undifferentiated glandular pattern is often a under-recognized histological pattern. Histological grading of severity was a novel attempt to correlate with clinical parameters. Significant plasma cell infiltrate and vascular proliferation in endometriotic foci, underscores the quest for novel therapeutic targets. This study suggests that the use of non-invasive diagnostic methods like fibroscan/inflammatory markers to clinically identify severe disease should be investigated further.

Abstract
Endometriosis is a benign chronic disease in women that is characterized by the presence of active foci of the endometrium or endometrial tissue occurring outside of the uterus. The disease causes disabling symptoms such as pelvic pain and infertility, which negatively affect a patient's quality of life. In addition, endometriosis imposes an immense financial burden on the healthcare system. At present, laparoscopy is the gold standard for diagnosing the disease because other non-invasive diagnostic tests have less accuracy. In addition, other diagnostic tests have low accuracy. Therefore, there is an urgent need for the development of a highly sensitive, more specific, and non-invasive test for the early diagnosis of endometriosis. Numerous researchers have suggested miRNAs as potential biomarkers for endometriosis diagnosis due to their specificity and stability. However, the greatest prognostic force is the determination of several miRNAs, the expression of which varies in a given disease. Despite the identification of several miRNAs, the studies are investigatory in nature, and there is no consensus on them. In the present review, we first provide an introduction to the dysregulation of miRNAs in patients with endometriosis and the potential use of miRNAs as biomarkers in the detection of endometriosis. Then we will describe the role of the mir-200 family in endometriosis. Several studies have shown that the expression of the mir-200 family changes in endometriosis patients, suggesting that they could be used as a diagnostic biomarker and therapeutic target for endometriosis.

An irreversible inhibitor of 17β-hydroxysteroid dehydrogenase type 1 inhibits estradiol synthesis in human endometriosis lesions and induces regression of the non-human primate endometriosis. J Steroid Biochem Mol Biol 2022; 222:106136. [PMID: 35691460 DOI: 10.1016/j.jsbmb.2022.106136] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 05/27/2022] [Accepted: 06/06/2022] [Indexed: 10/18/2022]
Abstract
Endometriosis is a gynecological disorder affecting about 10% of women and can lead to invalidating painful symptoms and infertility. Since there is no current definitive cure for this disease, new therapeutic options are necessary. 17β-Hydroxysteroid dehydrogenase type 1 (17β-HSD1) is involved in the production of estradiol (E2), the most potent estrogen in women, and of 5-androstene-3β,17β-diol (5-diol), a weaker estrogen than E2, but whose importance increases after menopause. 17β-HSD1 is therefore a pharmacological target of choice for the treatment of estrogen-dependent diseases such as endometriosis. We developed a targeted-covalent (irreversible) and non-estrogenic inhibitor of 17β-HSD1, a molecule named PBRM, and herein evaluated its efficiency for the treatment of endometriosis. In a cell-free assay containing estrone (E1), the natural substrate of 17β-HSD1, PBRM was able to block the formation of E2 in a collection of 50 human endometriosis lesions from a different clinical feature type, location, and phase. When given orally by gavage at 15 mg/kg to baboons, the resulting plasmatic concentration of PBRM was found to be sufficiently high (up to 125 ng/mL) for an efficacy study in a non-human primate (baboon) endometriosis model. After 2 months of treatment, the number of lesions/adhesions decreased in 60% of animals (3/5) in the PBRM-treated group, compared to the placebo group which showed an increase in the number of lesion/adhesions in 60% (3/5) of animals. Indeed, the total number of lesions/adhesions decreased in treated group (-6.5 or -19% when excluding one animal) while it increased in the control group receiving a placebo (+11%). Analysis of specific endometriotic lesions revealed that PBRM decreased the number of red lesions (-67%; 8/12) and white lesions (-35%; 11/31), but not of blue-black lesions. Similarly, PBRM decreased the surface area of dense adhesions and filmy adhesions, as compared to placebo. Also, PBRM treatment did not significantly affect the number of menstrual days. Finally, this targeted covalent inhibitor showed no adverse effects and no apparent toxicity for the duration of the treatment. These data indicate that 17β-HSD1 inhibitor PBRM is a promising candidate for therapy targeting endometriosis and supports the need of additional efforts toward clinical trials.

Abstract
Endometriosis is a chronic systemic disease that can cause pain, infertility and reduced quality of life. Diagnosing endometriosis remains challenging, which yields diagnostic delays for patients. Research on diagnostic test accuracy in endometriosis can be difficult due to verification bias, as not all patients with endometriosis undergo definitive diagnostic testing. The purpose of this State-of-the-Art Review is to provide a comprehensive update on the strengths and limitations of the diagnostic modalities used in endometriosis and discuss the relevance of diagnostic test accuracy research pertaining to each. We performed a comprehensive literature review of the following methods: clinical assessment including history and physical examination, biomarkers, diagnostic imaging, surgical diagnosis and histopathology. Our review suggests that, although non-invasive diagnostic methods, such as clinical assessment, ultrasound and magnetic resonance imaging, do not yet qualify formally as replacement tests for surgery in diagnosing all subtypes of endometriosis, they are likely to be appropriate for advanced stages of endometriosis. We also demonstrate in our review that all methods have strengths and limitations, leading to our conclusion that there should not be a single gold-standard diagnostic method for endometriosis, but rather, multiple accepted diagnostic methods appropriate for different circumstances. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
OBJECTIVE This study aimed to evaluate the validity of laparoscopic visualization for the diagnosis of endometriosis compared with histopathology. METHODS We conducted a retrospective chart review at a tertiary care hospital in Canada for the period of April 1, 2016 to March 31, 2017. Of 1069 women, 96 were selected for having undergone laparoscopic visualization and concurrent histopathological biopsy for suspected endometriosis. Standard measures of validity for diagnostic tests (sensitivity, specificity, positive predictive and negative predictive values, accuracy) were used. RESULTS Mean age of the 96 women included was 40 ± 7.2 years, and median gravidity and parity were 1 (IQR 0-3) and 0 (IQR 0-2), respectively. Common symptoms were abdominal and pelvic pain (41.7%), menstrual bleeding concerns (34.4%), dysmenorrhea (29.2%), and infertility (8.3%). Approximately one-third of women had endometriomas (31.3%), while more than half had deep infiltrating endometriosis (59.4%). The diagnosis of endometriosis was made by surgeons at laparoscopic visualization in 82.3% of women and by histopathology in 74.0%. Using histopathology as the gold standard, sensitivity for laparoscopic visualization was 90.1% (95% CI 81.0-95.1), while specificity was 40.0% (95% CI 23.4-59.3). Positive and negative predictive values were 81.0% (95% CI 71.0-88.1) and 58.8% (95% CI 36.0-78.4), respectively; and the accuracy was 77.1% (95% CI 67.7-84.4). CONCLUSION Although laparoscopic visualization had relatively high sensitivity and positive predictive value, its specificity and negative predictive value were relatively low. These findings support the use of laparoscopic visualization with histopathological analysis for accurate diagnosis of endometriosis.

Abstract
BACKGROUND We aimed to analyze the differences in the peripheral blood cells and tumor biomarkers between the patients with endometriosis and healthy people, and establish a more efficient combined diagnostic model. METHODS We retrospectively analyzed the differences in the peripheral blood cells and tumor biomarkers between the patients with endometriosis and healthy people. Binary logistic regression analysis was used to establish a combined diagnostic model. We plotted the receiver operator characteristic (ROC) curve to analyze the diagnostic efficiency of different diagnostic indexes. RESULTS Compared with patients in the control group, patients in the endometriosis group had significantly lower eosinophil% (p = 0.045), neutrophil (p = 0.001), lymphocyte (p < 0.001), red blood cells (RBCs) (p < 0.001), and hemoglobin (HGB) (p < 0.001), and had significantly higher monocyte% (p = 0.008), monocyte-to-lymphocyte ratio (MLR) (p = 0.001), platelet-to-lymphocyte ratio (PLR) (p < 0.001), carbohydrate antigen (CA)-199 (p < 0.001), CA125 (p < 0.001), human epididymis protein (HE)-4 (p < 0.001), and the risk of ovarian malignancy algorithm (ROMA) (p < 0.001). The combined diagnostic model of HGB, CA199, CA125, and HE4 was established by binary logistic regression analysis. The ROC curve showed that the combined diagnostic model reached a sensitivity of 85.4%, a specificity of 78.83%, and an area under the curve of 0.900, which was significantly higher than that of the individual index in endometriosis diagnosis. CONCLUSION The combined diagnostic model of HGB, CA199, CA125, and HE4 may provide a new approach for the early non-invasive diagnosis of endometriosis.

Abstract
The use of robotic-assisted laparoscopic surgery has continued to grow since the Food and Drug Administration approval for robotic-assisted gynecologic surgery in 2005. However, despite this growth in utilization, the data supporting its use in benign gynecologic surgery has not strongly supported its advantages over conventional laparoscopy. Controversy exists between supporters of robotic-assisted laparoscopic surgery and conventional laparoscopy. This article discusses the current literature regarding the use of robotic-assisted surgery in benign gynecologic surgery.

Improving the diagnostic recognition of thoracic endometriosis: Spotlight on a new histo-morphological indicator. PLoS One 2021; 16:e0251385.

Abstract
The diagnosis of thoracic endometriosis (TE) is challenging, hence resulting in under-diagnosis as well as long delays before arriving at a correct definitive diagnosis. Our aim is to review the histopathological findings in TE, summarise the diagnostic features, identify any major histo-morphological indicator(s) hitherto unrecognised as such, suggest diagnostic criteria; all with the aim of improving the diagnostic capacity and reducing observer error even where the clinical suspicion is low. A case-control study in which a search in the pathology archives of a referral hospital over a 10-year period was conducted. Twenty-six cases of TE were identified, reviewed, and compared with a control population of 48 cases taken from common benign thoracic diseases. Nine notable histological features were identified in varying permutations in the test group, namely: endometrioid glands, lymphoid clusters, ceroid macrophages, siderophages, cholesterol crystals, capillary congestion, multinucleated giant cells, smooth muscle bundles and fibrosis. The first 6 features were frequent; each being present in over 13 (13/26; 50%) test cases. The first 8 features showed significant association with TE by the Chi-squared test (P<0.05). In this group, the strength of association is high for the first 4 features (Cramér's V≥0.5). The presence of ceroid macrophages is shown to be a novel key feature, previously unrecognised as such, for the identification of TE. The presence of any three of four features including endometrioid glands, lymphoid clusters, ceroid macrophages and siderophages is a suggested criterion for the definitive diagnosis of TE.

Abstract
Endometriosis is generally histopathologically defined as the presence of at least 2 of the following: endometrial stroma, Müllerian epithelium, and/or hemosiderin-laden macrophages (HLM). Despite clinically evident endometriotic lesions, biopsies are frequently nondiagnostic. In this study, we conducted a large-scale review of biopsies of lesions clinically thought to represent endometriosis and correlate the histologic findings with clinical appearance to expand sensitivity of the pathologic definition of endometriosis, particularly in patients on hormonal therapy. In all, 112 biopsies from 78 patients (mean age=25, range 18-39 yr) were reviewed for histopathologic features suggestive of or diagnostic for endometriosis including the presence of endometrial stroma, Müllerian epithelium, dystrophic calcifications, HLM, chronic inflammation, adhesions, and vascular proliferation. Endometriosis was confirmed by pathologic criteria in 37 of 78 patients (47%). Biopsies from patients on hormonal therapy (n=62, 80%) were significantly less likely to meet pathologic criteria for endometriosis (P=0.01). Nondiagnostic biopsies (70/112; 63%) frequently displayed HLM (20%), chronic inflammation (29%), dystrophic calcifications (26%), vascular proliferation (20%), or adhesions (20%) and were significantly more likely to have a vascular clinical appearance (P=0.01). Diagnostic biopsies (42/112; 38%) were more likely to have a blue/black clinical appearance (P=0.03), demonstrate HLM (P=0.004), and display pseudodecidualization (P=0.05). Patients with a high clinical suspicion of endometriosis have a range of histologic findings, with less than half meeting the current histopathologic criteria for diagnosing endometriosis. Given the heterogeneous histopathologic appearance, revision of the histologic criteria may be warranted with further exploration, particularly for lesions with predominantly vascular features.

Abstract
As the diagnosis requires a laparoscopy, we only have data in women with pain and/or infertility. Endometriosis has been considered to be a single disease defined as 'endometrium like glands and stroma outside the uterus'. However, subtle, typical, cystic ovarian and deep endometriosis lesions should be considered to be different pathologies which occur in all combinations and with different severities. All large datasets, especially those based on hospital discharge records, consider endometriosis to be a single disease without taking into account severity. In particular, the variable prevalence and recognition of subtle lesions is problematic. Reliable surgical data are small series not permitting multivariate analysis. Endometriosis is a hereditary disease. The oxidative stress of heavy menstrual bleeding with retrograde menstruation and an altered pelvic microbiome are probably associated with increasingly severe endometriosis. Whether the prevalence is increasing, or whether endometriosis is associated with fat intake or an increased risk of cardiovascular disease is unclear.

Abstract
Cryoablation, as a well-characterized technology, has multifarious clinical applications. But few are reported on ureteral endometriosis. Thus, we examined the feasibility and safety of cryotherapy with a novel balloon cryoprobe on ureter in a live porcine model. During the freezing and thawing cycle, temperature was recorded in different parts of the ureter in real-time. Two-minute cryoablation could induce necrosis within range in 1 cm diameter on serosa layer. The temperature respectively dropped to -136.5 °C, -96.1 °C and -17.5 °C at the cryotherapy center, 1 cm and 1.5 cm from center on serosal side. The ureters were harvested immediately, 2 weeks or 3 months after cryotherapy. No perforation, stricture, adhesions, or hydronephrosis was observed. Histopathologic representations of ureters after cryoablation indicated that full thickness necroses of ureters were seen in all samples. The results demonstrated ureteral cryoablation using a novel balloon probe was feasible, safe, and effective. These findings provided us reference before cryoablation could be applied in clinical practice in treating ureteral endometriosis.

Abstract
The aim of the present case-control study was to develop a noninvasive adjuvant tool for the diagnosis of endometriosis. Serum samples from 100 patients undergoing intracytoplasmic sperm injection were split into two groups according to the cause of infertility: an endometriosis group (n = 50), consisting of samples derived from patients with Grade III and IV endometriosis, and a control group (n = 50), comprising samples derived from patients with isolated male factor infertility. The metabolomic profile of each sample was obtained, through mass spectrometry. Partial least squares discriminant analysis was able to clearly classify the endometriosis and control groups. Ten potential biomarkers were selected based on their importance for model prediction. These ions were used to build the receiver-operating characteristic curve, which presented an area under the curve of 0.904 (95% confidence interval: 0.796-0.985). To validate the model, 30 other samples from infertile women without any evidence of endometriosis were tested. Considering these ions as possible biomarkers, the model was able to correctly classify 84% of the patients. Finally, a similar prediction potential was observed in the model validated set, when samples from the disease-free group were tested. Serum metabolomics may be useful as a noninvasive adjunct tool for the selection of patients who must undergo laparoscopy for definitive endometriosis diagnosis.

Abstract
Endometriosis is a complex gynaecological condition affecting women of reproductive age. It is characterised by the presence of lesions containing endometrial glands and stroma outside the uterus. The disease is typically associated with pelvic pain (including dysmenorrhoea and dyspareunia), infertility and bowel-related symptoms. Endometriotic lesions have a highly variable presentation and most commonly occur in the abdominal cavity. These lesions are broadly classified into peritoneal, ovarian and deep infiltrating endometriosis. There have been observations of increased density of nerve fibres and neurological molecules in the endometriotic lesions compared to the uninvolved peritoneum of women without endometriosis and the presence of unmyelinated nerve fibres were higher near the glands. The lesion sites are characterised by a range of immunological alterations, and specific immune cell populations have also been known to synthesise and secrete neurogenic factors. Endometriotic lesions are capable of producing prostaglandins which are direct generators of pain and are capable of inducing inflammation. Diagnosing the disease involves direct visualisation of the lesions through a laparoscopic or laparotomy, which is followed by histopathological examination of biopsied or excised lesions. The staging of endometriosis due to its complexity is highly variable as presentation and gaps in knowledge pose a great challenge in the classification of the disease. The medical management of endometriosis aims at providing adequate analgesia and suppression of the activity of the lesion. A better understanding of endometriotic lesion relationships between innervations and specific clinical characteristics may elucidate aspects of pain mechanisms and infertility in endometriosis and facilitate the development of novel therapeutic approaches.

Abstract
BACKGROUND Chronic pelvic pain (CPP) symptoms in women are variable and non-specific; establishing a differential diagnosis can be hard. A diagnostic laparoscopy is often performed, although a prior magnetic resonance imaging (MRI) scan may beneficial. OBJECTIVES To estimate the accuracy and added value of MRI in making diagnoses of (1) idiopathic CPP and (2) the main gynaecological causes of CPP. To quantify the impact MRI can have on decision-making with respect to triaging for therapeutic laparoscopy and to conduct an economic evaluation. DESIGN Comparative test-accuracy study with cost-effectiveness modelling. SETTING Twenty-six UK-based hospitals. PARTICIPANTS A total of 291 women with CPP. METHODS Pre-index information concerning the patient's medical history, previous pelvic examinations and ultrasound scans was collected. Women reported symptoms and quality of life at baseline and 6 months. MRI scans and diagnostic laparoscopy (undertaken and interpreted blind to each other) were the index tests. For each potential cause of CPP, gynaecologists indicated their level of certainty that the condition was causing the pelvic pain. The analysis considered both diagnostic laparoscopy as a reference standard for observing structural gynaecological causes and consensus from a two-stage expert independent panel for ascertaining the cause of CPP. The stage 1 consensus was based on pre-index, laparoscopy and follow-up data; for stage 2, the MRI scan report was also provided. The primary analysis involved calculations of sensitivity and specificity for the presence or absence of each structural gynaecological cause of pain. A decision-analytic model was developed, with a 6-month time horizon. Two strategies, laparoscopy or MRI, were considered and populated with study data. RESULTS Using reference standards of laparoscopic and expert panel diagnoses, MRI scans had high specificity but poor sensitivity for observing deep-infiltrating endometriosis, endometrioma, adhesions and ovarian cysts. MRI scans correctly identified 56% [95% confidence interval (CI) 48% to 64%] of women judged to have idiopathic CPP, but missed 46% (95% CI 37% to 55%) of those considered to have a gynaecological structural cause of CPP. MRI added significant value, over and above the pre-index information, in identifying deep-infiltrating endometriosis (p = 0.006) and endometrioma (p = 0.02) as the cause of pain, but not for other gynaecological structural causes or for identifying idiopathic CPP (p = 0.08). Laparoscopy was significantly more accurate than MRI in diagnosing idiopathic CPP (p < 0.0001), superficial peritoneal endometriosis (p < 0.0001), deep-infiltrating endometriosis (p < 0.0001) and endometrioma of the ovary (p = 0.02) as the cause of pelvic pain. The accuracy of laparoscopy appeared to be able to rule in these diagnoses. Using MRI to identify women who require therapeutic laparoscopy would lead to 369 women in a cohort of 1000 receiving laparoscopy unnecessarily, and 136 women who required laparoscopy not receiving it. The economic analysis highlighted the importance of the time horizon, the prevalence of CPP and the cut-off values to inform the sensitivity and specificity of MRI and laparoscopy on the model results. MRI was not found to be a cost-effective diagnostic approach in any scenario. CONCLUSIONS MRI was dominated by laparoscopy in differential diagnosis of women presenting to gynaecology clinics with CPP. It did not add value to information already gained from history, examination and ultrasound about idiopathic CPP and various gynaecological conditions.

Abstract
OBJECTIVE To provide clinical practice guidelines from the French college of obstetrics and gynecology (CNGOF) with the Haute Autorité de santé (HAS), based on the best evidence available, concerning the diagnosis accuracy of endoscopy (laparoscopy, hysteroscopy, fertiloscopy, cystoscopy, colonoscopy) in case of endometriosis. MATERIAL AND METHODS English and French review of literature about the diagnosis accuracy of endoscopy in case of endometriosis. RESULTS AND CONCLUSION Laparoscopy is useful in case of suspected endometriosis in patients with symptoms or infertility when appropriate preoperative assessment is negative (grade C). Biopsies during diagnosis laparoscopy are recommended in case of typical or atypical lesions to confirm endometriosis (grade B). It is not recommended to perform fertiloscopy in case of suspected endometriosis (grade C). Hysteroscopy could be performed in case of suspected endometriosis and infertility to eliminate endometrial polyp or septate uterus (grade C). Colonoscopy is not recommended in case of suspected deep posterior endometriosis (grade C).

Abstract
PURPOSE OF REVIEW Surgery can be an important treatment option for women with symptomatic endometriosis. This review summarizes the recommended preoperative work up and techniques in minimally invasive surgery for treatment of deeply infiltrating endometriosis (DIE) involving the obliterated posterior cul-de-sac, bowel, urinary tract, and extrapelvic locations. RECENT FINDINGS Surgical management of DIE can pose a challenge to the gynecologic surgeon given that an extensive dissection is usually necessary. Given the high risk of recurrence, it is vital that an adequate excision is performed. With improved imaging modalities, preoperative counseling and surgical planning can be optimized. It is essential to execute meticulous surgical technique and include a multidisciplinary surgical team when indicated for optimal results. SUMMARY Advanced laparoscopic skills are often necessary to completely excise DIE. A thorough preoperative work up is essential to provide correct patient counseling and incorporation of the preferred surgical team to decrease complications and optimize surgical outcomes. Surgical management of endometriosis is aimed at ameliorating symptoms and preventing recurrence.

Abstract
The main objective of this study was to compare results of using the robotic 3D/HD scope and the 2D/HD laparoscope for visual detection of histologically confirmed endometriosis. Three surgeons from different practices enrolled premenopausal women ≥18 years who had elected to undergo robotic-assisted endometriosis resection. Patients were randomized to receive 2D/HD laparoscopic visualization either before or after 3D/HD robotic visualization. Resections then proceeded robotically. The number of histologically confirmed lesions overall and by abdomino-pelvic location, appearance and size was compared by scope type used. During the study, 598 lesions were visualized in 98 patients. Average number of lesions per patient using either scope was 6.1. Mean age was 31 years and 77% were disease stage I/II. On histopathology, 58.4% of lesions resected were consistent with endometriosis. All (100%) of these lesions were detected using the robotic 3D/HD scope and 77.9% using the 2D/HD laparoscope (p < 0.001). Compared to laparoscopic, robotic visualization resulted in detection of more confirmed lesions in all anatomic locations and for most appearances, including the cul-de-sac (100 vs. 79%), atypical appearance (100 vs. 71.3%) and width <5 mm (100 vs. 62%), p's < 0.001). Logistic regression indicated that use of the 3D/HD robotic scope was independently associated with 2.36 times the likelihood (95% CI 1.20, 4.66; p = 0.014) of detecting a confirmed lesion, compared to the 2D/HD laparoscope. Large-scale, long-term studies are needed to substantiate these findings in multiple practice settings and to determine whether 3D robotic versus 2D laparoscopic resection has a beneficial impact on symptomatology, recurrence and fertility outcomes.

Abstract
Endometriosis is a common gynecological disease with high prevalence, while its etiology and pathophysiology have remained to be fully elucidated. Previous evidence suggested that this disorder may be in part or completely of somatic origin. However, traditional endometrial samples may not be ideal for investigation, as target cells, including epithelial and stromal cells, in endometriotic lesions are too sparse to be analyzed. Recently, capture microdissection techniques have been used to overcome these limitations and eliminate tissue heterogeneity in endometriosis research. Therefore, the present review summarized the alterations in epithelial and stromal cells in endometriosis tissues isolated through capture microdissection, outlined recent progress and provided directions for future investigation of the pathogenesis of endometriosis.

Abstract
Background No screening programs are available for ovarian or endometrial cancer. One reason for this is the low incidence of the conditions, resulting in low positive predictive values for tests, which are not very specific. One way of addressing this problem might be to use risk factors to define subpopulations with a higher incidence. The aim of this study was to investigate the extent to which a medical history of endometriosis can serve as a risk factor for ovarian or endometrial cancer. Methods In a hospital-based case–control analysis, the cases represented patients with endometrial or ovarian cancer who were participating in studies aimed at assessing the risk for these diseases. The controls were women between the age of 40 and 85 who were invited to take part via a newspaper advertisement. A total of 289 cases and 1016 controls were included. Using logistic regression models, it was tested whether self-reported endometriosis is a predictor of case–control status in addition to age, body mass index (BMI), number of pregnancies and previous oral contraceptive (OC) use. Results Endometriosis was reported in 2.1 % of the controls (n = 21) and 4.8 % of the cases (n = 14). Endometriosis was a relevant predictor for case–control status in addition to other predictive factors (OR 2.63; 95 % CI, 1.28 to 5.41). Conclusion This case–control study found that self-reported endometriosis may be a risk factor for endometrial or ovarian cancer in women between 40 and 85 years. There have been very few studies addressing this issue, and incorporating it into a clinical prediction model would require a more precise characterization of the risk factor of endometriosis.

Abstract
OBJECTIVE To determine agreement on endometriosis diagnosis between real-time laparoscopy and subsequent expert review of digital images, operative reports, magnetic resonance imaging (MRI), and histopathology, viewed sequentially. DESIGN Inter-rater agreement study. SETTING Five urban surgical centres. POPULATION Women, aged 18-44 years, who underwent a laparoscopy regardless of clinical indication. A random sample of 105 women with and 43 women without a postoperative endometriosis diagnosis was obtained from the ENDO study. METHODS Laparoscopies were diagnosed, digitally recorded, and reassessed. MAIN OUTCOME MEASURES Inter-observer agreement of endometriosis diagnosis and staging according to the revised American Society for Reproductive Medicine criteria. Prevalence and bias-adjusted kappa values (κ) were calculated for diagnosis, and weighted κ values were calculated for staging. RESULTS Surgeons and expert reviewers had substantial agreement on diagnosis and staging after viewing digital images (n = 148; mean κ = 0.67, range 0.61-0.69; mean κ = 0.64, range 0.53-0.78, respectively) and after additionally viewing operative reports (n = 148; mean κ = 0.88, range 0.85-0.89; mean κ = 0.85, range 0.84-0.86, respectively). Although additionally viewing MRI findings (n = 36) did not greatly impact agreement, agreement substantially decreased after viewing histological findings (n = 67), with expert reviewers changing their assessment from a positive to a negative diagnosis in up to 20% of cases. CONCLUSION Although these findings suggest that misclassification bias in the diagnosis or staging of endometriosis via visualised disease is minimal, they should alert gynaecologists who review operative images in order to make decisions on endometriosis treatment that operative reports/drawings and histopathology, but not necessarily MRI, will improve their ability to make sound judgments. TWEETABLE ABSTRACT Endometriosis diagnosis and staging agreement between expert reviewers and operating surgeons was substantial.

Abstract
Background: We investigated possible biomarkers for endometriosis (EM) using the ClinProt technique and proteomics methods. Methods: We enrolled 50 patients with EM, 34 with benign ovarian neoplasms and 40 healthy volunteers in this study. Serum proteomic spectra were generated by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MS) combined with weak cationic exchange (WCX) magnetic beads. Possible biomarkers were analyzed by a random and repeat pattern model-validation method that we designed, and ClinProtools software, results were refined using online liquid chromatography-tandem MS. Results: We found a cluster of 5 peptides (4210, 5264, 2660, 5635, and 5904 Da), using 3 peptides (4210, 5904, 2660 Da) to discriminate EM patients from healthy volunteers, with 96.67% sensitivity and 100% specificity. We selected 4210 and 5904 m/z, which differed most between patients with EM and controls, and identified them as fragments of ATP1B4, and the fibrinogen alpha (FGA) isoform 1/2 of the FGA chain precursor, respectively. Conclusions: ClinProt can identify EM biomarkers, which – most notably – distinguish even early-stage or minimal disease. We found 5 stable peaks at 4210, 5264, 2660, 5635, and 5904 Da as potential EM biomarkers, the strongest of which were associated with ATP1B4 (4210 Da) and FGA (5904 Da); this indicates that ATP1B4 and FGA are associated with EM pathogenesis.

Abstract
Endometriosis is classically defined as the presence of endometrial glands and stroma in outside the uterine cavity. As the definition suggests that confirming the ectopic endometrial stroma and glands in ectopic location histopathologically should be necessary for the diagnosis of endometriosis. Therefore, this situation leads to the need for surgery like laparoscopy for diagnosis. However, this surgical diagnostic approach will not be reliable for all patients with suspected endometriosis. It seems to be an important problem that there is still no reliable clinically diagnostic method or pathognomonic clinical finding, which may allow accurate diagnosis of endometriosis without the need for surgery or histopathologic evaluation. While these clinical features are not pathognomonic for the endometriosis, they should be used as markers for creating high-risk population for endometriosis. Clinical features and the available diagnostic methods, their advantages and limitations for the endometriosis will be discussed in this article. The different options for clinical assessment, laboratory tests and imaging techniques will be summarized and the advantages and disadvantages of these methods will be evaluated. We will also discuss the gold standard definitive diagnostic options with their problematic aspects.

Abstract
STUDY OBJECTIVE To evaluate the ability of narrow band imaging (NBI) in conjunction with standard white light imaging to improve the detection and diagnosis of endometriosis during laparoscopic evaluation compared with white light imaging alone. Sensitivity of NBI in detecting endometriosis was assessed and compared with white light imaging. DESIGN Randomized controlled trial. CLASSIFICATION OF STUDY DESIGN LEVEL I: Evidence obtained from a properly designed, randomized, controlled trial. SETTING The trial was conducted in 2 medical centers. PATIENTS One hundred sixty-seven women undergoing laparoscopic evaluation for suspected endometriosis and/or infertility were recruited. Of these, 150 were assessable to determine sensitivity of NBI compared with white light imaging for the detection of endometriotic lesions. INTERVENTIONS Patients were randomized in a 3:1 ratio to receive white light imaging followed by NBI or white light imaging only. The pelvis was systematically visualized with each assigned imaging modality; lesions were recorded under each visualization and then resected. All patients had white light imaging on the first visualization followed by either a second white light examination (control arm) or NBI examination (intervention arm). MEASUREMENTS Pathology of resected lesions was the criterion standard for evaluating sensitivity and was conducted at each institution. The method of detection of the lesion (white light or NBI) was masked. Central pathology review was conducted for a randomly selected 10% sample of specimens and for those lesions visualized under only 1 imaging modality among patients assigned to the intervention arm. The sensitivity was assessed for each modality (white light and NBI) and compared using a McNemar's test. MAIN RESULTS Among the group randomized to receive both white light and NBI, 4 patients had lesions detected with NBI but no lesions detected with white light. Among the 255 lesions confirmed as endometriosis by pathologic review, all were detected by NBI for a sensitivity of 100%; 79% were detected by white light imaging (p < .001). CONCLUSION The addition of NBI to white light imaging increased the number of endometriotic lesions identified during laparoscopy and the diagnosis of endometriosis compared with the use of white light imaging alone.

Abstract
Endometriosis is defined as the presence of endometrial glands and stroma outside the uterus, in different parts of the peritoneal cavity. It affects up to 10% of reproductive-age women and up to 50% of women with infertility. Surgical diagnosis of endometriosis is still the gold standard, with no diagnostic biomarkers available. Medical therapies target the symptoms and not the disease itself, and surgical treatment cannot prevent recurrence. As peritoneal fluid reflects the altered peritoneal microenvironment of endometriosis patients, it can provide a wealth of information on pathophysiological processes and potential biomarkers. This report reviews the molecular biomarkers identified in peritoneal fluid over the last 5 years and discusses their potential applications for diagnosis, prognosis and drug therapy.

Abstract
This study was undertaken to test the hypotheses that, due to gradual accumulation of dead erythrocytes and their ingested products resulting from repeated hemorrhage, older endometriomas (whitish in color) contain chocolate fluid with higher iron content than younger (brownish/blackish in color) ones with concomitant higher collagen content and more adhesions. We recruited 30 premenopausal women with histologically confirmed ovarian endometriomas and collected samples of their endometriotic lesions and chocolate fluid and measured the viscosity, density, and the concentration of total bilirubin, ferritin, and free iron of the chocolate fluid. We also evaluated the lesion color and adhesion scores. In addition, we performed Masson trichrome and Picro-Sirius red staining on all endometriotic cysts and evaluated the extent of fibrosis in the lesions. We found that fluids taken from white-colored endometriomas had significantly higher concentration of total bilirubin, ferritin, and free iron, respectively, than black/brown-colored ones. In addition, older cysts had fluids that had significantly higher density and viscosity. Fluid density correlated positively with the concentrations of total bilirubin, ferritin, and free iron. Older lesions had significantly more collagen content and higher adhesion scores. Taken together, these data supports the notion that older cysts, having experienced more bleeding episodes, contain chocolate fluid that is higher in viscosity, density, and iron content and higher fibrotic content than younger ones. This provides another piece of evidence that endometriotic lesions are wounds that undergo repeated injury and repair, resulting ultimately fibrotic lesions that are resistant to hormonal treatment.

Abstract
Endometriosis affects 10% of premenopausal women and 35-50% of women with infertility, pelvic pain, or both. At present, endometriosis can only be diagnosed with surgery, where laparoscopy is considered a gold standard. Noninvasive biomarkers are thus urgently needed. In 2010, the peripheral biomarkers of endometriosis were systematically reviewed by May et al. However, with the introduction of '-omics' technologies, we have witnessed immense progress in biomarker discovery, which now calls for an overview of recent studies. This report looks at potential blood and urine biomarkers of endometriosis published in the last 3 years. The current status of noninvasive diagnostic biomarkers of endometriosis is discussed, with the limitations of these studies identified and recommendations for future biomarker discovery provided.

Abstract
Endometriosis affects up to 10% of women of reproductive age and 176 million women worldwide. The prevalence in women with infertility is between 30% and 50% but may be higher in women with pelvic pain, interstitial cystitis, or irritable bowel syndrome. Cytokeratin 19 has been suggested as a potential biomarker in urine for the diagnosis of this condition. The objective of this study was to prospectively determine the accuracy and the performance of a urinary cytokeratin 19 (uCYFRA 21-1) test for diagnosing endometriosis. Ninety-eight consecutive women who underwent laparoscopy had a urinary sample obtained before surgery and were included in the study. Endometriosis was diagnosed by laparoscopy and pathology in 64.3% (63 of 98 women). The estimates and 95% confidence intervals for sensitivity, specificity, positive and negative predictive values, and likelihood ratios were 11.1% (4.5%-21.5%), 94.3% (80.8%-99.3%), 77.7% (39.9-97.1), 37% (27-47.9), 1.94 (0.43-8.86), and 0.94 (0.84-1.06), respectively. Despite the high specificity, the uCYFRA 21-1 test has limited value for clinical practice to discriminate between women with and without endometriosis.

Abstract
Purpose The aim of this study was to develop a noninvasive screening tool for patients with chronic pelvic pain, for early-stage endometriosis, with a discriminatory ability of the area under the curve (AUC) for the receiver operator characteristic (ROC) curve of over 0.8. Methods Participants were women aged 13-55 years, with chronic pelvic pain (for more than 6 months despite medical therapy), seen at the Saint Louis University Center for Endometriosis, from January 2012 to June 2013, who were found to have early-stage endometriosis or not, based on histology. All patients received the same surgical approach and goal of surgery, which was excision of all visible abnormal peritoneum. Potential variables used for generating the screening tool came from the pre-operative questionnaire with standard pain symptoms and quality-of-life questions. Individual categorical variables were tested. In addition, new binary variables were created to test specific combinations of answers to 2 individual questions. A backwards-stepping multiple logistic regression model was used to develop the screening tool. Results Ninety patients found to have early-stage disease completed pre-operative surveys. Of these, 70 (77.8%) had histologically confirmed endometriosis and 20 (22.2%) were confirmed not to be affected. Combinations of 2 variables made it possible to create a predictive model for early-stage endometriosis with excellent discriminatory ability (AUC = 0.822, p<0.001). This model was generated using a multi-staged, backwards stepping logistic regression analysis with all variables that were univariately significant included in the initial model (p<0.025). The final model had 80.5% sensitivity and 57.7% specificity. The model allows for an individual probability of disease to be calculated for each patient. Conclusions A clinically useful, symptom-based screening tool was developed for early-stage endometriosis in patients with chronic pelvic pain seen at a referral center. This approach to developing a screening tool for endometriosis should be tested further.
