Effect of laparoscopy by single-port endoscopic access in benign adnexal surgery: study protocol for a randomized controlled trial

Background Laparoscopic surgery has become the preferred surgical approach due to a reduction in postoperative pain, better recovery, shorter hospitalization, and improved esthetic outcomes. Laparoscopic surgery with single-port laparoscopy (SPL) is a laparoscopic surgery technique that is based on making a single parietal incision using a single trocar specifically designed to allow introduction of several instruments. The level of evidence regarding the advantages of SPL in terms of postoperative pain has remained low despite several randomized studies. Adult patients exhibiting a surgical indication for an a priori benign ovarian pathology or for prophylactic purposes that can be performed by laparoscopy will be randomized to receive conventional laparoscopy (CL) or SPL. The aim of our study is to evaluate whether SPL offers advantages over CL in benign adnexal surgery.
