Roux-en-Y Gastric Bypass Surgery
The Roux-en-Y gastric bypass procedure has been performed more than any other weight loss surgery and is commonly known simply as “gastric bypass.” The name of this surgery, Roux-en-Y, is derived from the surgeon who first described it (Cesar Roux) and the fact that the Roux-en-Y surgery creates a shape that looks like the letter Y within the intestines.
Performed by an estimated 80 percent of obesity surgeons in the country, roux-en-y gastric bypass has a successful 30-year track record with a minimal number of complications.

Roux-en-Y Surgery – How It WorksIn the Roux-en-Y surgery, the top portion of the stomach is separated and stapled off from the larger, lower portion of the stomach, creating a restrictive one-ounce pouch. The pouch is then connected to a channel of intestine that carries only food, causing food to bypass the rest of the stomach and a section of the small intestine. The intestine is divided into two distinct channels to prevent food and digestive juices from mixing, resulting in intentional mal-absorption of calories from food. This surgery can be done laparoscopically or through an abdominal incision, based on the needs of the patient.
