Initial entry via the left upper quadrant with an optical trocar in laparoscopic bariatric surgery

Abstract

Introduction: Laparoscopic bariatric surgery (BS) is not readily performed in Japan. To facilitate safe initial access to the abdominal cavity, we insert an optical viewing trocar at a unique site in the left upper quadrant (LUQ).Herein, we describe the technique, its advantages, and outcomes.Materials and Surgical Technique: Briefly, the optical trocar is inserted just below the left subcostal margin, 8 cm from the midline. On insertion, layers of the abdominal wall are visualized on the monitor. Depending on the angle of insertion, five, seven, or eight layers are seen.
