Abstract: Objective: To evaluate the clinical outcomes of endometrial reepithelialization between hysteroscopic scissors and resectoscope in those patients underwent transcervical resection of septum (TCRS). Methods: This is a randomized controlled study  including 60 women with partial septate uterus, in our center from January 2015 to December 2016. Thirty cases underwent hysteroscopic metroplasty using hysteroscopic scissors (group A) and 30 cases had the procedure using the bipolar electrodes (group B). Main characteristics of the patients and operative parameters (operative time, blood loss, complications) were recorded. The hysteroscopic examination was performed after 1 and 2 months of surgery to evaluate the endometrial healing process including endometrial reepithelialization, intrauterine adhesions and residual suptum. Results: Although the operating time in the group A was significantly faster than that in the group B [(13.90±3.95) min vs. (23.13±5.15) min，P=0.00], there was no significant difference in the blood loss between the 2 groups [(8.67±2.25) mL vs. (8.83±2.15) mL，P=0.77]. There were not any intraoperative complications in two groups, and intrauterine adhesion or residual septum in two months follow-up visit. The poor reepithelialization in the group A was less than that in the group B [16.67% (5/30) vs. 93.33% (28/30), P=0.00], in the 1 month′s visit. However, the endometrium reepithelialization was completely satisfied in two groups after surgery. Conclusions: The endometrial reepithelialization is faster in the scissors group than that in the resectoscope group in the first month after surgery. However, the epithelialization status can be well satisfied in two groups within 2 months.
