Laparoscopic duodenal switch is a recognized bariatric procedure, which can be performed in one step or as a second step after laparoscopic sleeve gastrectomy (LSG). Mainly, indications as primary surgery are super-obese or super super-obese patients, and after LSG indications are the presence of insufficient weight loss or weight regain, associated with morbid obesity co-morbidities, without gastroesophageal reflux. In this video, the authors report the technique of reduced port laparoscopic duodenal switch after LSG. The procedure is performed using a 12-mm trocar in the umbilicus, a 5-mm trocar in the right flank, and a 5-mm trocar in the left flank. One or more temporary percutaneous sutures are passed into the hepatic ligaments to increase the exposure of the first duodenum. The optical system is switched from 10 mm to 5 mm and introduced in the left 5-mm flank trocar at the step of the linear stapler insertion through the umbilical trocar. Classic construction with 150-cm alimentary limb and 100-cm common limb is performed. The duodeno-jejunostomy is fashioned in an end-to-side handsewn technique and the jejuno-ileostomy in the side-to-side semimechanical linear stapler technique. Both Petersen and mesenteric defects are closed. The umbilical access is finally meticulously closed, avoiding incisional hernia. Reduced port laparoscopic duodenal switch after LSG is a safe and feasible technique. Besides the enhanced cosmetic outcomes, this surgery is associated with a reduced use of painkillers, fewer trocar complications, and quick patient convalescence.
