Large ovarian endometriomas are associated with high pre-operative anti-Müllerian hormone concentrations.

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 (P = 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 (P = 0.02 and P = 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.

Postoperative Outcomes after Surgery for Deep Endometriosis of the Sacral Plexus and Sciatic Nerve: A 52-patient Consecutive Series.

STUDY OBJECTIVE: To assess 1-year postoperative outcomes of surgery for deep endometriosis involving the sacral roots and sciatic nerve. DESIGN: Retrospective case series. SETTING: Three referral centers. PATIENTS: Fifty-two women. INTERVENTIONS: Surgery for deep endometriosis involving the sacral roots and sciatic nerve. MEASUREMENTS AND MAIN RESULTS: Deep endometriosis involved the sacral roots in 49 women (94.2%) and the sciatic nerve in 3 cases (5.8%). Sciatic pain (buttock or leg) was recorded in 43 women (82.7%), pudendal neuralgia in 11 women (21.2%), and leg motor weakness in 14 cases (27%). The surgical procedures carried out on the pelvic nerves included complete release and decompression (92.3%), excision of the epineurium by shaving (5.8%), and intraneural excision (1.9%). Additional major surgical procedures involved the digestive tract in 82.7% of the cases and the urinary tract in 46.2%. Rectovaginal fistula occurred in 13.5% of the cases. Self-catheterization was required in 14 cases (27%) at 3 weeks after surgery and in 3 women (5.8%) 12 months later. One-year follow-up showed significant improvement in quality of life measured using the Short-Form 36 questionnaire and standardized gastrointestinal scores. De novo hypoesthesia, hyperesthesia, or allodynia were recorded in 9 women (17.2%). The cumulative pregnancy rate was 77.2%% after natural conception in 47%. CONCLUSION: Laparoscopic management of deep endometriosis involving the sacral roots and sciatic nerve improves patients' symptoms and overall quality of life. Although pain reduction may be rapid after surgery, other sensory or motor complaints, including bladder dysfunction, may be recorded over months or years.
