Association of preoperative Enzian score with postoperative fertility in patients with deep pelvic endometriosis.

INTRODUCTION: Endometriosis is a chronic inflammatory disease with a negative impact on fertility. The Enzian classification provides a precise description of deep pelvic endometriotic lesions, especially in the retroperitoneal area, from preoperative pelvic MRI scans. However, it is not known if it is correlated with postoperative fertility. STUDY OBJECTIVE: To determine if there is an association between the preoperative Enzian score and postoperative fertility after deep pelvic endometriosis surgery. DESIGN: We conducted a descriptive, retrospective study using information from the ENDOREN database. SETTING: This was a retrospective study at the Department of Obstetrics and Gynecology at Rennes University Hospital (France) from January 2013 to May 2019 PATIENTS AND INTERVENTIONS: We used information from the ENDOREN database that included all women who underwent surgery for deep endometriosis and wish to conceive. This surgery was intended in a view to achieve a complete removal of endometriosis. MEASUREMENTS: The Enzian score was calculated from preoperative MRI scans, and total, spontaneous, and after In Vitro fertilization (IVF) live births and pregnancies outcomes were collected from the patients'computerized medical records. Univariate and multivariate analysis was performed. RESULTS: Sixty-eight patients were included. The live-birth rate was 35% (24/68). According to the Enzian classification, 25 patients (35%) were classified in compartment A, 64 patients (94%) in compartment B, and 27 (40%) in compartment C. In multivariate analysis, positive predictor of live birth was single Enzian B score (OR=4.7[1.21; 18.81], p = 0.03), negative predictors were uterine adenomyosis and a history of endometriosis surgery. In multivariate analysis, positive predictor of spontaneous live birth was EFI score ≥7 (OR =22.434; CI [1.138; 442.190]). In multivariate analysis, positive predictor was Enzian A score (OR=15.9[2.2; 114.7], p = 0.006), and negative predictors was uterine adenomyosis and Enzian B score (OR=0.01[0; 0.495], p = 0.02) for live birth after IVF. CONCLUSION: The present retrospective study cannot strongly conclude about fertility and correlation with Enzian score because the groups are too small. However, it seems that when solely the compartment B is involved by endometriosis, complete full removal of endometriosis leads to better post-operative live births results. Other studies must be done to determine if Enzian classification based on preoperative pelvic MRI could be clinical value in the decision-making strategy for managing infertile patients with deep pelvic endometriosis.

Operative Technique and Experience of One Referral Center With Vaginal Cesarean Delivery.

BACKGROUND: To report the experience of vaginal cesarean delivery and describe the surgical technique. METHOD: This is a retrospective case series from one referral center of patients who underwent vaginal cesarean delivery from 2000 to 2017, presenting a step-by-step operative technique with a video. The operative technique consists of: 1) development of a transvaginal bladder flap by dissecting the bladder off the cervix, thereby exposing the lower uterine segment; 2) making a vertical segment incision up to the highest part of the lower uterine segment, just below the muscular portion of the uterus; 3) extraction of the fetus; and 4) reconstruction of the lower uterine segment and vagina. EXPERIENCE: Seven patients with maternal indications for urgent premature delivery who underwent vaginal cesarean delivery were included. Indications were severe bleeding (n=3), severe previable preeclampsia (n=2), severe heart failure (n=1), and stroke (n=1). The average gestational age at delivery was 21 2/7 weeks (18 2/7-24 1/7 weeks); median fetal birth weight was 300 g (179-500 g). There were no intraoperative complications attributable to the procedure. CONCLUSION: Vaginal cesarean delivery is a valuable technique for rapid fetal extraction of deceased or nonviable fetuses for severe maternal indications.
