Types of Weight Loss Surgery: Roux-en-Y Gastric Bypass Surgery

Friday, October 23, 2009 by Terri Hohlt
This operation is the most common and successful malabsorptive surgery. First, a small stomach pouch is created to restrict food intake. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the lower stomach, the duodenum (the first segment of the small intestine), and the first portion of the jejunum (the second segment of the small intestine). This bypass reduces the amount of calories and nutrients the body absorbs. It is the primary surgery performed by The Clarian Bariatric Center.

This operation can be performed either by a traditional open surgery or laparoscopically, a relatively new technology using a small video camera and a few customized instruments to perform surgery with minimal tissue damage. The Roux-en-Y technique is generally more effective in reversing health problems associated with severe obesity. Patients who have malabsorptive operations generally lose two-thirds of their excess weight within two years.
