Smaller incisions of the abdominal wall reduce postoperative pain and the risk of wound complications, and provide an excellent cosmetic result compared with open surgery. Flexible endoscope-based transgastric, transcolonic, or transvaginal surgery for abdominal exploration, cholecystectomy, appendectomy, and tubal ligation may further reduce the surgical invasion.展开更多
