Roux-en-Y Gastric Bypass
One of the most popular and successful surgical approaches is the Roux-en-Y gastric bypass, which is a minimally invasive procedure, performed with small video cameras called laparoscopes. In gastric bypass surgery, the stomach is reduced in size so that only a small amount of food can be eaten at one time. Patients lose weight because this small pouch restricts the amount of food that can be eaten comfortably. This method uses small incisions, which result in less pain, reduced risk of infections and a faster recovery for the patient. Gastric-bypass surgery has been endorsed by a 1991 consensus panel of the National Institutes of Health as an effective means of inducing significant long-term weight loss for the vast majority of patients with clinically severe obesity.
