Single anastomosis (mini-) gastric bypass for the treatment of Asian type 2 diabetes mellitus

Bariatric surgery is the most efficacious therapy for morbid obesity today, and now moving from bariatric surgery to metabolic surgery for the treatment of type 2 diabetes mellitus (T2DM). Advancement in laparoscopic technique contributed to a rapid surge of the volume of bariatric surgery. However, the type of bariatric/metabolic procedures evolved over the past 60 years and is still evolving. Single anastomosis (mini-) gastric bypass (SAGB) was first proposed by Dr. Robert Rutledge in 2001. Many surgeons across the world have strong concerns to this procedure but do not perform it. Although controversy existed, tens of thousands of this procedure have been reported throughout the world with universally good results. The advantages of this procedures included technique simplicity, shorter learning curve, easy to convert and better weight loss and co-morbidities resolution. However, data about the result of SAGB specifically for the treatment of T2DM in Asian is less known. The review examines the current status, long-term result of SAGB on weight reduction and the efficacy on T2DM treatment in Asian.
