Transumbilical single-incision laparoscopic sleeve gastrectomy.

Background: Sleeve gastrectomy has become an established primary bariatric surgical technique. Its relatively lower complexity has made it eligible to be performed by single-incision laparoscopy (single-incision laparoscopic sleeve gastrectomy, SILSG). The aim of this paper is to present our SILSG technique and surgical outcomes and demonstrate that SILSG is a safe and feasible procedure using conventional laparoscopic instruments.
