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.
Roux-en-y gastric bypass has a successful track record with a minimal number of complications.
