Roux-en-Y Gastric Bypass
|
The Roux–en–Y Gastric Bypass (RYGB) is among the most frequently performed weight loss procedures in the United States and one of the weight loss surgeries offered at the Methodist Willowbrook Surgical Weight Loss Center. Named after Swiss surgeon César Roux, who first began using the Y–shaped loop technique in gastrointestinal surgeries in 1892, the RYGB is a malabsorptive, restrictive procedure designed to redirect food to a pouch surgically created in the stomach, bypassing part of the small intestine.
The first part of RYGB entails the creation of a small pouch in the stomach, restricting the amount of food that can be consumed. The larger part of the stomach is then separated from the pouch though not removed. The small intestine just below the duodenum is divided, the jejunum portion is then brought up and connected to the newly created pouch and the duodenum is reconnected to the new intestinal limb – forming a "Y" shape. Bypassing the duodenum prevents the absorption of calories and nutrients, which results in weight loss.
Who Is A Candidate For Roux–en–Y Gastric Bypass?
Those considered good candidates for RYGB include patients with a Body Mass Index of more than 40, and/or who suffer from life-threatening obesity-related diseases but are physically able to withstand such a surgical procedure.
