Gastic bypass - the procedures

October 07, 2002

Although there are several variations, two types of weight-loss operations are effective, according to the National Institutes of Health.

Banded gastroplasty restricts gastric volume by stapling off a section of the stomach.

The front and back walls of the stomach are stapled together; a circular window is cut to allow a polypropylene band to be placed around the lower end of the pouch to keep it from stretching, according to information on the Web site of the American Society of Bariatric Surgery, www.asbs.org.

Roux-en-Y gastric bypass restricts gastric volume and alters digestion by redirecting the small intestine, bypassing some of the area in which food would meet up with digestive juices, resulting in reduced absorption of food.
