Comparison of Self-Locking Versus Traditional Sutures in Double-Layer Laparoscopic Vaginal Vault Closure After Hysterectomy (BI-SURE Trial)

Vaginal vault closure after laparoscopic or robotic hysterectomy may be associated with postoperative complications such as vaginal cuff dehiscence, infection, and bleeding. The optimal suture material and technique for laparoscopic colporrhaphy, particularly in patients undergoing surgery for gynecologic malignancies, remain controversial. The BI-SURE trial is a multicenter, randomized controlled study designed to compare double-layer self-locking sutures versus double-layer traditional Polyglactin 910 sutures for laparoscopic vaginal vault closure after hysterectomy. The study aims to evaluate postoperative effectiveness and safety within three months after surgery.
