Objective: To evaluate cervical function and pregnancy outcomes after hysteroscopic resection of the complete uterine septum, duplicate cervix and vaginal septum with Metzenbaum scissors. Methods: Between January 2010 and December 2016, 13 patients admitted to the Department of Obstetrics and Gynecology of Sir Run Run Shaw Hospital with complete uterine septum, duplicate cervix and vaginal septum, were enrolled into this study. The cervical and corporal septum was cut by Metzenbaum scissors, and residual septum was cut by micro scissors under hysteroscopy. The vaginal septum was cut with the unipolar electric knife. Results: The operation time was about 10 ± 1.31 min. All the 13 patients present normal uterine cavities without scar formation under hysteroscopy at 3 months after operation, there was mild adhesions between anterior and posterior intrauterine wall on 2 cases. After operation, there were 13 pregnancies naturally conceived in 11 patients, 10 deliveries. The live birth rate was 76.92%, the early miscarriage rate was 23.08%. The cesarean section rate was 30%, the vaginal delivery rate was 70%, and all were term births. Conclusion: The operation was simple, convenient, and fast, without any complications and cervical insufficiency. It was easy to have vaginal deliveries.
