A simple technique of vaginal cuff closure to prevent tumor cell spillage in laparoscopic radical hysterectomy for uterine cervical cancer

Abstract

Introduction: The Laparoscopic Approach to Cervical Cancer (LACC) trial, a prospective randomized phase III clinical trial reported in 2018, unexpectedly showed inferior oncologic outcomes in laparoscopic radical hysterectomy (LRH) for cervical cancer compared with those in open surgery. It was proposed that the spillage of tumor cells into the peritoneal cavity might cause the inferiority of LRH. It has been suggested, based on retrospective studies, that transvaginal closure of the vaginal cuff before the colpotomy part of the surgery may prevent this.

Materials and surgical technique: Before starting colpotomy, we closed the vaginal cuff transvaginally. After the assessment of the cutline of the vagina, the vaginal mucosa is pulled at the eight sites using the sutures. The four pairs of sutures on the diagonal line are ligated. A purse string suture is additionally placed on the vaginal mucosa to close the vaginal cuff completely. After that, we start the intracorporeal colpotomy using a vaginal pipe.

Discussion: Our technique is simple and quick. The blood loss during the transvaginal procedures is minimal. The use of the vaginal pipe helps keep the vaginal cuff closed during the colpotomy. Our technique may be an alternative to the conventional approach closing the vaginal cuff.
