RESUMO
RESEARCH QUESTION: Are large ovarian endometriomas associated with high pre-operative anti-Müllerian hormone (AMH) concentrations? DESIGN: Data from 332 women who underwent AMH measurement before surgery for endometriosis were prospectively recorded in a large database. Univariate analysis compared AMH concentrations in terms of the patients' baseline characteristics. A multivariate model was used to identify variables having an independent relationship with AMH concentration. RESULTS: Among 332 women included in the study, 47.6% were aged 18-30 years, 67.8% were infertile and 85.5% were nulliparous. A total of 66.3% had ovarian endometriomas, and 10.8% had cysts measuring over 6 cm. Bilateral cysts over 3 cm were recorded in 24.7% of the women. Univariate analysis identified two variables that had a statistically significant relationship with AMH concentration: the woman's age (Pâ¯=â¯0.01) and cyst size (P < 0.001). Multivariate analysis revealed that ages of 36-40 years and over 40 years showed a significant association with lower AMH concentrations (Pâ¯=â¯0.02 and Pâ¯=â¯0.009, respectively), while a cyst size of over 6 cm was statistically associated with high AMH concentrations (P < 0.001), after adjustment for smoking, parity, rectosigmoid endometriotic nodules and a bilateral location of endometriomas. CONCLUSIONS: Pre-operative AMH concentration was significantly increased in women with large endometriomas of over 6 cm, independent of their age or the presence of bilateral endometriomas. This is relevant for both surgeons and patients when planning surgery in women with an intention to conceive post-operatively.

STUDY OBJECTIVE: To compare the probability of postoperative pregnancy in infertile women with ovarian endometrioma larger than 3 cm in diameter, managed by either ablation using plasma energy or cystectomy. DESIGN: A multicentric case-control study (Canadian Task Force classification II-2). SETTING: Six surgical departments, affiliated with 4 university hospitals and 2 private facilities. PATIENTS: One hundred four infertile patients with ovarian endometrioma larger than 3 cm. INTERVENTIONS: Endometrioma ablation using plasma energy was performed in 64 patients (61.5%) and cystectomy in 40 patients (38.5%). MEASUREMENTS AND MAIN RESULTS: Patients were enrolled in the CIRENDO prospective cohort database (NCT02294825) from June 2009 to June 2014 and managed in 6 different facilities. The minimum length of follow-up was 1 year. Postoperative probabilities of pregnancy in patietns and control subjects were estimated using the Kaplan-Meier method with 95% confidence intervals (CIs) and compared using the log-rank test. The Cox model was used to assess independent predictive factors for pregnancy. Patients managed by plasma energy were significantly older than patients managed by cystectomy, had significantly higher overall revised American Fertility Society (rAFS) score, and had higher rate of Douglas pouch obliteration, deep endometriosis, and colorectal localizations. After a mean follow-up of 35.3 ± 17.5 months (range, 12-60), fertility outcomes were comparable between the groups. The probability of pregnancy at 24 and 36 months after surgery in plasma energy and cystectomy groups was, respectively, 61.3% (95% CI, 48.2%-74.4%) versus 69.3% (95% CI, 54.5%-83%) and 84.4% (95% CI, 72%-93.4%) versus 78.3% (95% CI, 63.8%-90%). The Cox's model revealed that the type of surgical procedure on ovarian endometrioma had no statistically significant impact on the probability of pregnancy, after adjustment for women's age, bilateral cysts larger than 3 cm, colorectal endometriosis, and rAFS stage of endometriosis. CONCLUSION: Postoperative pregnancy rates were comparable after management of ovarian endometrioma by either ablation using plasma energy or cystectomy despite an overall higher rate of unfavorable fertility predictive factors in women managed by ablation.

INTRODUCTION: Despite extensive research endometriosis is an area with important controversies. The European Society of Human Reproduction and Embriology issued in 2014 the last Guideline for endometriosis management including the statement that among 83 recommendations in 32 cases the best available evidence was only based on good clinical practice, further research being necessary to solve the lack of evidence in this pathology. The prevalence of endometriosis is unknown in Romania but in the medical literature estimates range from 2 to 10% of women of reproductive age, to 50% of infertile women, worldwide. Ovarian endometrioma prevalence goes up to 44%. A Cochrane review published in 2008 by Hart et al. concluded that excisional surgery of ovarian endometriosis results in a more favorable outcome compared to drainage and ablation with regard to recurrence, pain symptoms and subsequent spontaneous pregnancy in subfertilewomen- so the gold standard was set. But several authors revealed that ovarian tissue was inadvertently excised together with the cyst wall and endometrioma cystectomy is associated with a significant decrease in residual ovarian volume that may result in diminished ovarian reserve and function. The aim of our retrospective study was to evaluate whether or not ovarian parenchyma is inadvertently removed during laparoscopic surgery for endometrioma in a Romanian academic center. MATERIAL AND METHOD: We performed a retrospective study including women having undergone endometrioma excision, between January 2009 to June 2014 in the Department of Gynecology and Obstetrics of Targu-Mures University Hospital. Histological specimens of excised endometriomas were reviewed by different pathologists, who carried out serial microscopic sections according to pathology protocol for diagnosis of ovarian mass but not specific for the ovarian parenchyma removed with the cyst. RESULTS: Among 202 endometriomas, drainage and ablation was done in 60 cases and excisional surgery in the remaining 152 cases. Ovarian parenchyma was found in 40% of cases of endometrioma cystectomy. DISCUSSION: We observed that endometrioma cystectomy leads to ovarian tissue removal in an important number of cases. Furthermore, at the time of surgery the amount of ovarian parenchyma loss may increases proportionally with increases in cyst diameter and patient age. Considering that most of the woman in our series were infertile and because of data from series using plasma energy, a shift in the endometrioma treatment paradigm is likely to occur.

OBJECTIVE: To compare differences in the postoperative pregnancy rate in women seeking to conceive and presenting with endometriomas larger than 3 cm in diameter, which were managed by ablation using plasma energy, cystectomy, or simple drainage. METHODS: A retrospective three-arm comparative study based on prospective collection of data evaluating 363 patients, undergoing endometrioma cystectomy, ablation using plasma energy, or simple drainage. RESULTS: In this series, 204 (56.2%) patients underwent endometrioma ablation using plasma energy, 121 (33.3%) received cystectomy, and 38 (10.5%) had a simple drainage. Postoperative follow up was 50 ± 26 months. Overall postoperative pregnancy rate was 60.3%. The probability of being pregnant after cystectomy, ablation, and drainage was respectively 27%, 32%, and 16% at 12 months, with a statistically significant difference between pregnancy rates among the three arms (P = 0.015). Simple drainage was associated with a probability of conception over 50% after 2 years, mainly based on postoperative assisted reproductive technology. CONCLUSIONS: We reveal good postoperative pregnancy rate after ablation using plasma energy or cystectomy for endometriomas. Surgical management should be carefully considered in women with endometriomas and pregnancy intention, because the postoperative pregnancy rate may be compared with that observed after first-line assisted reproductive technology management.

OBJECTIVE: To compare postoperative pregnancy rates as they relate to presurgery antimüllerian hormone (AMH) level in patients with stage 3 and 4 endometriosis. DESIGN: Retrospective comparative study using data prospectively recorded in the North-West Inter-Regional Female Cohort for Patients with Endometriosis (CIRENDO) database. SETTING: University tertiary referral center. PATIENT(S): One hundred eighty patients with stage 3 and 4 endometriosis and pregnancy intention, managed from June 2010 to March 2015, were divided into two groups according to their preoperative AMH levels: group A (AMH ≥2 ng/mL) and group B (AMH <2 ng/mL). INTERVENTION(S): Surgical procedure involved ovarian endometrioma ablation by plasma energy along with resection of various localizations of the disease. Postoperative conception was either spontaneous or used assisted reproductive technology, depending on patient characteristics. MAIN OUTCOME MEASURE(S): Patient characteristics, preoperative symptoms, infertility history, intraoperative findings, and probability of pregnancy were recorded and compared between the two groups. RESULT(S): Among 180 women enrolled in the study, 134 (74.4%) were assigned to group A and 46 (25.6%) to group B. The women's ages were, respectively, 30 ± 3.8 and 32 ± 4.6 years. Pregnancy was achieved by 134 (74.4%) patients, and conception was spontaneous in 74 of them (55.2%). Pregnancy rates in groups A and B were, respectively, 74.6% (100 women) and 73.9% (34 women), while spontaneous conception represented 54% (54 women) and 58.8% (20 women). The probability of pregnancy at 12, 24, and 36 months after surgery in groups A and B was comparable, respectively, 65% (95% confidence interval [CI], 55%-75%), 77% (95% CI, 86%-68%), and 83% (95% CI, 90%-75%) versus 50% (95% CI, 69%-34%), 77% (95% CI, 90%-61%), and 83% (95% CI, 94%-68%). Supplementary analysis in women with normal (≥2 ng/mL), low (1-1.99 ng/mL), and very low (<1 ng/mL) AMH level showed an inverse relationship between AMH level, age, and antecedents of miscarriage; however, postoperative pregnancy rates were comparable among the three groups at 12 and 24 months, respectively, 59.5% (95% CI, 49.3%-70%) and 77.4% (95% CI, 68%-85.4%); 57.1% (95% CI, 34%-83%) and 78.6% (95% CI, 55.2%-94.8%); and 46.7% (95% CI, 25.6%-73.7%) and 73.3% (95% CI, 50.4%-91.7%). CONCLUSION(S): The probability of postoperative pregnancy was comparable between women with low and normal AMH level who were managed for stage 3 and 4 endometriosis and who were a mean age of 30 years. However, the small sample size might have been unable to detect differences in pregnancy and live-birth rates between the two groups. As the majority of pregnancies were spontaneous, our results suggest that surgical management may be offered to young patients with severe endometriosis and reduced ovarian reserve with good fertility outcomes.
