Application of three dimensional laparoscope in metabolic and bariatric surgery

With the rapid development of minimally invasive techniques, the emergence of three dimensional (3D) laparoscope leading minimally invasive surgical access "Precise Time". In the past 60 years, bariatric surgery provides a large number of clinical evidences to confirm: metabolic and bariatric surgery is lasting and effective for obesity combined with type 2 diabetes mellitus (T2DM), and it is also the best treatment method for T2DM. The author believes that 3D laparoscopic system can help beginners quickly master laparoscopic surgical techniques and shorten the learning curve to master the technical points. Compared with twodimensional (2D) laparoscopic surgery, 3D laparoscopic stereo vision can help experienced baria tric surgeons shorten operation time which is related to surgical procedures. The shorter surgical procedure in laparoscopic sleeve gastrectomy is hardly affecting the operation time. Because gastric bypass surgery is relatively complex, 3D laparoscopic techniques which are fully utilized in gastric bypass surgery can effectively shorten the operation time.
