One type of bypass gastric surgery is called biliopancreatic diversion with duodenal switch. It involves bypassing the duodenum and jejunum by detaching the lleum part of the small intestine from the duodenum and jejunum and reattaching it to the pouch part of the stomach created by resection. During resection, up to 80 percent of the stomach has been removed, hence the stomach can allow only a small portion of food, and the digestive tract can only digest a small portion. Although effective, biliopancreatic diversion with duodenal switch requires more follow-through regarding nutritional care and is considered a high maintenance procedure.
