This procedure is also known as biliopancreatic diversion with duodenal switch (BPD-DS) or simply, the duodenal switch.
Duodenal Switch – How It Works
In this procedure, both the stomach and intestines are altered. Most of the stomach and cells containing ghrelin are removed. The remaining portion of the stomach is stapled off, creating a 3-5 ounce pouch.
The intestines are divided and rearranged to separate food from the digestive juices for a good portion of its journey. Food bypasses 40-60 percent of the small intestine, and mixes with digestive juices farther down the intestines. This prevents the body from absorbing all of the calories that are eaten.
