- Endometriosis classification systems: an international survey to map current knowledge and uptake(2022) ZONDERVAN, Krina T.; MISSMER, Stacey; ABRAO, Mauricio S.; I, Jon Einarsson; HORNE, Andrew W.; JOHNSON, Neil P.; LEE, Ted T. M.; PETROZZA, John; TOMASSETTI, Carla; VERMEULEN, Nathalie; GRIMBIZIS, Grigoris; WILDE, Rudy L. deBackground: In the field of endometriosis, several classification, staging and reporting systems have been developed and published, but there are no data on the uptake of these systems in clinical practice. Objectives: The objective of the current study was to examine whether clinicians routinely use the existing endometriosis classification systems, which system do they use and what are the clinicians' motivations? Materials and Methods: A cross-sectional study was performed to gather data on the current use of endometriosis classification systems, problems encountered and interest in a new simple surgical descriptive system for endometriosis. Of particular focus were three systems most commonly used: the Revised American Society for Reproductive Medicine (rASRM) classification, the Endometriosis Fertility Index (EFI), and the ENZIAN classification. Data were analysed by SPSS. A survey was designed using the online SurveyMonkey tool consisting of 11 questions concerning three domains-participants' background, existing classification systems and intentions with regards to a new classification system for endometriosis. Replies were collected between 15 May and 1 July 2020. Main outcome measures: Uptake, feedback and future intentions. Results: The final dataset included the replies of 1178 clinicians, including surgeons, gynaecologists, reproductive endocrinologists, fertility specialists and sonographers, all managing women with endometriosis in their clinical practice. Overall, 75.5% of the professionals indicate that they currently use a classification system for endometriosis. The rASRM classification system was the best known and used system, the EFI system and ENZIAN system were known by a majority of the professionals but used by only a minority. The lack of clinical relevance was most often selected as a problem with using any system. The findings of the survey suggest that clinicians worldwide are open to using a new classification system for endometriosis that can achieve standardised reporting, and is clinically relevant and simple. Conclusions: Even with a high uptake of the existing endometriosis classification systems (rASRM, ENZIAN and EFI), most clinicians managing endometriosis would like a new simple surgical descriptive system for endometriosis. What is new? The findings therefore support future initiatives for the development of a new descriptive system for endometriosis and provide information on user expectations and conditions for universal uptake of such a system.
- Elagolix reduced dyspareunia and improved health-related quality of life in premenopausal women with endometriosis-associated pain(2019) LEYLAND, Nicholas; TAYLOR, Hugh S.; ARCHER, David F.; PELOSO, Paul M.; SOLIMAN, Ahmed M.; PALAC, Hannah L.; MARTINEZ, Marisol; ABRAO, Mauricio S.Objectives: The objective was to evaluate the effects of elagolix on dyspareunia in women with endometriosis-associated pain. Methods: Data were pooled from two similar, randomized, double-blind, placebo-controlled, 6-month phase 3 studies (Elaris Endometriosis-I and Elaris Endometriosis-II) of elagolix at two doses (150 mg QD and 200 mg BID) in women with endometriosis-associated pain. In this post hoc analysis, dyspareunia responders were defined as having a clinically meaningful decrease from baseline in the dyspareunia score and decreased or stable use of rescue analgesic agents, as recorded in a daily electronic diary. Sexual relationship was assessed using the 30-item Endometriosis Health Profile questionnaire sexual relationship module. Results: A total of 1384 women reported > 1 day of sexual activity at baseline (35 days prior to and including day 1 of treatment). Of these 1384 women, 1297 (94%) reported > 1 day of any dyspareunia (mild, moderate, or severe), of which 51% reported > 1 day of severe dyspareunia. Among sexually active women who reported any dyspareunia at baseline, both elagolix doses led to improvements in dyspareunia. Women in the 200-mg BID group showed more months at which the dyspareunia response rates were statistically significantly greater than placebo, particularly in a subgroup of women with severe dyspareunia at baseline. Compared to placebo, both elagolix doses led to statistically significantly greater improvements in the mean 30-item Endometriosis Health Profile sexual relationship module score. Conclusion: Up to 6 months of elagolix treatment improved dyspareunia in women with endometriosis-associated pain in a dose-dependent manner, with 200-mg BID dose showing the most significant improvements in dyspareunia and quality of sexual relationships compared with placebo.

- An international terminology for endometriosis, 2021(2021) TOMASSETTI, Carla; JOHNSON, Neil P.; PETROZZA, John; ABRAO, Mauricio S.; I, Jon Einarsson; HORNE, Andrew W.; LEE, Ted T. M.; MISSMER, Stacey; VERMEULEN, Nathalie; ZONDERVAN, Krina T.; GRIMBIZIS, Grigoris; WILDE, Rudy Leon DeSTUDY QUESTION: Can a set of terms and definitions be prepared on endometriosis that would be the basis for standardization in disease description, classification and research? SUMMARY ANSWER: The current paper outlines a list of 49 terms and definitions in the field of endometriosis. WHAT IS KNOWN ALREADY: Different classification systems have been developed for endometriosis, using different definitions for the disease, the different subtypes, symptoms and treatments. In addition, an International Glossary on Infertility and Fertility Care was published in 2017 by the International Committee for Monitoring Assisted Reproductive Technologies (ICMART) in collaboration with other organisations. STUDY DESIGN, SIZE, DURATION: An international working group convened over the development of a classification or descriptive system for endometriosis. As a basis for such a system, a terminology for endometriosis was considered a condition sine qua non. The working group listed a number of terms relevant to be included in the terminology, documented currently used and published definitions, and discussed and adapted them until consensus was reached within the working group. Following stakeholder review, further terms were added, and definitions further clarified. PARTICIPANTS/MATERIALS, SETTING, METHODS: Although definitions were collected through published literature, the final set of terms and definitions is to be considered consensus-based. After finalization of the first draft, the members of the international societies and other stakeholders were consulted for feedback and comments, which led to further adaptations. MAIN RESULTS AND THE ROLE OF CHANCE: A list of 49 terms and definitions in the field of endometriosis is presented, including a definition for endometriosis and its subtypes, different locations, interventions, symptoms and outcomes. Endometriosis is defined as a disease characterized by the presence of endometrium-like epithelium and/or stroma outside the endometrium and myometrium, usually with an associated inflammatory process. LIMITATIONS, REASONS FOR CAUTION: Future research may require further refinement of the presented definitions. WIDER IMPLICATIONS OF THE FINDINGS: The application of the defined terms aims to facilitate harmonization in endometriosis research and clinical practice.
- The microbiome and endometriosis(2022) MIYASHIRA, Carlos H.; OLIVEIRA, Fernanda Reali; ANDRES, Marina Paula; GINGOLD, Julian A.; ABRAO, Mauricio SimoesThe objective of this study was to systematically review the literature on the human microbiome in association with endometriosis. PubMed/Medline, Cochrane, and Embase databases were searched for literature published from 1986 to August 2021. All human studies that assessed the microbiome using 16S rRNA sequencing or shotgun sequencing in women with endometriosis were included. Two reviewers independently abstracted data from the selected articles into tables. To assess the quality of included studies, the National Institutes of Health Study Quality Assessment Tools were utilized. This review included 12 case-control studies. Included studies compared the microbiome from various anatomical sources (fecal, vaginal, cervical, peritoneal, endometrial, and intra-lesional) between patients with endometriosis and a heterogeneous set of control patients. Study quality ranged from poor to good, with 8 of 12 studies rated fair. Multiple studies reported a different distribution of bacteria among women with endometriosis across anatomical sites, but the results were highly heterogeneous. Pseudomonas was overrepresented in peritoneal fluid among women with endometriosis across multiple studies but was also observed to be increased in vaginal, endometrial, and intra-lesional samples. Among bacteria noted across different anatomical samples, Gardnerella was found to be increased in cervical but decreased in endometrial, fecal, and vaginal samples of patients with endometriosis, while Atopium was found to be decreased in vaginal and cervical samples from patients with endometriosis. Sphingobium was found to be increased in vagina, endometrium, and peritoneal fluid from patients with endometriosis. Streptococcus was found to be increased in peritoneal, endometrial, and cervical samples from women with endometriosis. Microbiomal comparisons stratified by endometriosis stage or site of endometriosis involvement were limited and highly heterogeneous. Lay summary The microbiome, a group of bacteria found in a particular place in the body, has been shown to vary when patients have some diseases, such as cancer or inflammatory bowel disease. Less is known about the microbiome in patients with endometriosis. This review looked at existing studies comparing the bacteria found in patients with endometriosis and others without. Twelve studies were found that assessed the bacteria from swabs collected from different places, including the vagina, cervix, endometrium, peritoneum, feces, and endometriosis lesions themselves. Most of the studies found higher or lower levels of specific bacteria at each of these places, but the findings were often inconsistent. The findings were probably limited by the small numbers of patients involved and variations in the groups studied. More research is needed to find out which bacteria are over- and underrepresented in patients with endometriosis and where they are found.
- Endometriosis classification systems: an international survey to map current knowledge and uptake(dagger)(double dagger)(2022) ZONDERVAN, Krina T.; MISSMER, Stacey; ABRAO, Mauricio S.; I, Jon Einarsson; HORNE, Andrew W.; JOHNSON, Neil P.; LEE, Ted T. M.; PETROZZA, John; TOMASSETTI, Carla; VERMEULEN, Nathalie; GRIMBIZIS, Grigoris; WILDE, Rudy Leon DeSTUDY QUESTION Which classification system for endometriosis do clinicians use most frequently, and why? SUMMARY ANSWER Even with a high uptake of the three existing endometriosis classification systems, most clinicians managing endometriosis would like a new simple surgical descriptive system for endometriosis. WHAT IS KNOWN ALREADY In the field of endometriosis, several classifications, staging and reporting systems have been developed and published, but there are no data on the uptake of these systems in clinical practice.

The vast majority of respondents replied positively to the question on whether they would use a simple surgical descriptive system available for endometriosis, if available. LIMITATIONS, REASONS FOR CAUTION While the total number of respondents was acceptable, some regions/professions were not sufficiently represented to draw conclusions. WIDER IMPLICATIONS OF THE FINDINGS The findings of the survey suggest that clinicians worldwide are open to using a new classification system for endometriosis that can achieve standardized reporting and is clinically relevant and simple.

- Preoperative Ultrasound Scoring of Endometriosis by AAGL 2021 Endometriosis Classification Is Concordant with Laparoscopic Surgical Findings and Distinguishes Early from Advanced Stages(2023) ABRAO, Mauricio S.; ANDRES, Marina Paula; GINGOLD, Julian A.; RIUS, Mariona; NETO, Joao Siufi; GONCALVES, Manoel Orlando; GIOVANNI, Alessandra Di; MALZONI, Mario; CARMONA, FranciscoStudy Objective: To compare the accuracy of preoperative ultrasound (US) in predicting the laparoscopically defined 2021 American Association of Gynecologic Laparoscopists (AAGL) Endometriosis Staging. Design: Retrospective multicenter study of patients treated at 3 specialized endometriosis centers. Setting: Three specialized endometriosis surgical centers in Sao Paulo (Brazil), Barcelona (Spain), and Avellino (Italy) participated. Patients: A total of 878 patients aged 15 to 45 years with no history of pelvic malignancy underwent laparoscopic (LPS) treatment for suspected endometriosis. Interventions: Retrospective review of preoperative transvaginal and transabdominal US (index test) assessed for endometriosis at all sites used in the 2021 AAGL Endometriosis Classification and classified patients into AAGL-US stages 1 to 4. Results were compared with reference-standard LPS (AAGL-LPS) staging. Measurements and Main Results: The AAGL-US and AAGL-LPS stage were concordant in 586 cases (66.7%) (weighted kappa [WK] 0.759; intraclass correlation = 0.906), with the highest agreement observed in patients with no endometriosis (n = 70, 75.3% concordance), AAGL-LPS stage 1 (104, 50.7%) and stage 4 disease (358, 88.2%). Endometriosis was most accurately diagnosed in the rectum/sigmoid colon (WK 0.862), bladder (WK 0.911), and ovaries (WK 0.835/0.795 for right/left, respectively) and least accurately diagnosed at superficial peritoneal (WK 0.442), tubal (WK 0.391/0.363 for right/left, respectively), and retrocervical/uterosacral ligament (WK 0.656) sites. Conclusion: Sonographic estimation of the 2021 AAGL Endometriosis Staging is greatest in AAGL-LPS stages 1 and 4 and among patients with no endometriosis. US best identifies endometriosis of the ovaries, bladder, and bowel but is more limited for the tubes and superficial peritoneum. Journal of Minimally Invasive Gynecology (2023) 30, 363- 373.
