Biliopancreatic Diversion with Duodenal Switch Procedure in Iran
This procedure is a two steps surgery which begins with sleeve gastrectomy to remove a large part of the stomach. The valve is left along with the duodenum (the first part of the small intestine). Then, the middle section of the intestine will be closed off and the last part of the duodenum will be attached to the first part. This is the duodenal switch. The separated section of the intestine isn’t removed from the body. Instead, it’s reattached to the end of the intestine, allowing bile and pancreatic digestive juices to flow into this part of the intestine. This is the biliopancreatic diversion.
As a result of these changes, food bypasses most of the small intestine, limiting the absorption of calories and nutrients. This, together with the smaller size of the stomach, leads to weight loss.
