Abstract: Objective：To explore the improvement of reproductive outcome in those women with a complete bicornuate uterus who underwent metroplasty by the laparoscopy combined with hysteroscopy. Methods: 19 women with complete bicornuate uteri who underwent metroplasty by the laparoscopy combined with hysteroscopy in our hospital from October 2006 to November 2015 were retrospectively analyzed. The pregnancy outcome was followed-up. Results: 19 women were followed up for 2 to 11 years, and 4 of them dropped. In 15 women, 9 cases of pregnancy and 6 cases of non-pregnancy were recorded after their one-year effective postoperative contraception. The first postoperative pregnancy time after metroplasty ranges from 14 to 46 months. For the 9 women who had conception, the rates of spontaneous abortion (90.5% vs. 10.0%), term delivery (0 vs. 50.0%) and "take-home-baby" (0 vs. 80.0%) were recorded before and after the operation (all P＜0.05). Of the 19 patients, a total of 4 patients with complete bicornuate uteri combined with cervical insufficiency underwent laparoscopic abdominal cerclage before pregnancy, and 2 of them achieved successful pregnancy and delivered live babies. Conclusions: The metroplasty by the laparoscopy combined with hysteroscopy can significantly improve the reproductive prognosis for those women with adverse pregnancy outcomes owing to complete bicornuate uterus.
