Learning curve and perioperative outcomes associated with laparoendoscopic single-site surgery

Laparoendoscopic single-site (LESS) surgery represents the newest innovation in minimally invasive surgery. This approach further enhances the cosmetic benefits of laparoscopy while attempting to minimize the morbidity associated with multiple muscle-splitting incisions. Reports in the gynecology, general surgery, and urology literature have demonstrated the feasibility and safety of this technique in the performance of a variety of procedures. Numerous studies in the gynecologic surgery literature directly contrast the outcomes of LESS with those of conventional laparoscopy. Additionally, several randomized trials have been performed to date with the same intention. Measures of postoperative pain are favorable, and the incidence of incisional cellulitis, umbilical hernia formation, and other complications are low in women undergoing gynecologic LESS.
