Biliopancreatic Diversion with Duodenal Switch Operation
Part of Stomach Removed
During the Duodenal Switch gastric bypass operation, instead of bypassing the lower part of the stomach, a part of the stomach is removed leaving a pouch with a capacity of about 6oz. This limits the amount of food the patient can eat at one time.
Intestine Reconnected
The small intestine is then cut and reconnected in such a way that food travels one way and digestive juices (from pancreas and bile ducts) travels another way. They only join up for a very short span of intestine shortly before it becomes the large intestine. This greatly decreases the amount of nutrients, fat and calories that are absorbed from foods eaten.
Nutritional Deficiency - Supplements Needed
As with the biliopancreatic diversion malabsorptive surgical procedure, Duodenal Switch patients must follow a special diet as well as a lifelong program of vitamin and mineral supplements.
Duodenal Switch Success Rates
Patients who have malabsorptive weight loss surgery, like Duodenal Switch, generally lose two-thirds of their excess weight within 2 years.
