Strategies and thoughts on selection of bariatric surgery

Bariatric surgery has been widely accepted around the world and recognized for long-term and effective weight loss, based on long-term follow-up of large sample sizes. Though more than 70 years of development, bariatric surgery is not only on open technique, it is usually done by laparoscopy. But with the advance of the new technology, laparoscopy is no longer a unique technique. With the development of new robotic system and endoscopic system, bariatric and metabolic surgery has come to a new era. There is no doubt that bariatric surgery is still on the change as the development of scientific technology. Laparoscopic technique is still the mainstream of bariatric and metabolic surgery. With the decrease in the price of robotic system and the appearance of domestic robotic system, the robotic technique will also be accepted by many surgeons. The endoscopic technique is a tendency for bariatric and metabolic surgery because of effective weight loss, small trauma and low complication rates.
