Single incisional laparoscopic sleeve gastrectomy (SILSG) has been proposed as an alternative approach to the conventional multiport laparoscopic procedure. However, there has been no reported SILSG case in Korea, even though single incisional laparoscopic distal gastrectomy for early gastric cancer has increasingly reported in Korea and Japan. We recently performed 5 cases of SILSG for morbidly obese Korean patients, one of whom was 14-year-old adolescent female patient. Here, we describe our technical strategy for SILSG and present a brief review of literature about adolescent bariatric surgery.

Laparoscopic gastrectomy for gastric cancer has been used for more than 20 years, and gastric cancer treatment is now shifting to a new era because of innovations in surgical instruments and technical advances. Single port gastrectomy (SPG) for gastric cancer has recently been introduced in Korea and Japan. SPG is the ultimate reduced port technique in the view of surgical approaches because the operation is performed through a single incision in the abdominal wall. The first case of SPG was reported in 2010 by Omori and the first case in Korea was reported in 2011 by Park. Because of its short history, the benefits of laparoscopic gastrectomy have not yet been fully evaluated. This review describes the current situation, challenges and the future perspectives of single port laparoscopic gastrectomy for gastric cancer.

While conventional laparoscopy is the gold standard for bariatric procedures, robot platforms can provide better ergonomics for the surgeon, better visualization of the anatomy, easier dissection through articulated devices, which cannot be supported by laparoscopy. This review explores the literature and examines the reported outcomes and complications in using robotics for bariatric surgery. Robotic approaches to adjustable gastric banding, sleeve gastrectomy, gastric bypass, biliopancreatic diversion with duodenal switch, and revisional surgery are examined. Although many studies suffer from low levels of evidence, robotic application in the field of bariatric surgery continues to evolve with increasing literature and technology in surgical robotics.
