What does Roux-en-Y mean?
The Roux-en-Y (pronounced roo-in-Y) procedure is named partly after a 19th century French surgeon, Dr. Phillibart Roux, who initially introduced the idea of bypass surgery. After surgery, the stomach and intestine form a Y shape—one branch of the Y is the short intestinal limb and the other is formed by the duodenum. Refer to image above.
