Treatment of Twenty-two Patients with Complete Uterine and Vaginal Septum

Study Objective: To assess the fertility and obstetric outcome after surgical treatment of complete uterine and vaginal septum.

Design: Retrospective study (Canadian Task Force Classification II-2).

Setting: Teaching hospital in France.

Patients: Twenty-two women who have experienced infertility, pregnancy losses, dyspareunia, or dysmenorrhea.

Intervention: Hysteroscopic section of complete uterine septum and resection of longitudinal vaginal septum.

Measurements And Main Results: Improvement of dyspareunia or dysmenorrhea and obstetric outcome, focusing on the miscarriage rate, obstetric complications, and the gestational age at delivery were assessed. Overall, 20 women had conceived a total of 37 pregnancies, with 10 and 8 deliveries before and after metroplasty, respectively. Median gestational age at delivery was not significantly different in both groups (36.5 [33-39.5] vs 38.0 weeks' gestation [35-40], respectively). Preterm delivery occurred in 4 cases (25%) before the surgery and in 3 cases (14%) after (p = .44). The live birth rate was also not significantly different before and after surgery (62.5% and 38%, respectively) (p = .19). There was a decrease of caesarean section and significantly fewer breech deliveries after metroplasty (p = .01). A decrease in the prevalence of dyspareunia or dysmenorrhea was observed after metroplasty in the 19 patients originally displaying these symptoms. No perioperative complications were observed in this series.

Conclusion: Resection of vaginal septum and hysteroscopic metroplasty for complete uterine septum with resection of the cervical septum is a safe procedure that may improve dyspareunia and dysmenorrhea when present. Reproductive and obstetric outcomes after this procedure do not appear to be compromised, even though a relatively high miscarriage rate remains after metroplasty, questioning its systematic practice in symptom-free women without any previous obstetric history.
