Abstract
Since the development of gastric bypass 50 years ago by Mason and Ito, Roux-en-Y gastric bypass (RYGB) gradually become the most durable and commonly performed bariatric surgery. RYGB has been shown to be effective in achieving significant and durable long-term weight loss as well as improving medical co-morbidities in morbidly obese patients, and currently regarded as a gold standard bariatric/metabolic procedure. Recently, RYGB became the most commonly performed metabolic surgery for the treatment of type 2 diabetes mellitus (T2DM). Many reports about metabolic surgery are coming from this region because of the characters of Asian T2DM patients. In this review, the current literature evidence about the long-term result of RYGB on weight control and diabetic remission in Asian T2DM patients will be analyzed.
