In a biliopancreatic diversion with duodenal switch, a portion of the
stomach is removed, but the pylorus remains intact. The pylorus controls food drainage from the stomach. The pylorus is connected to a lower segment of the intestine. The duodenum is connected to the lower
part of the small intestine. The food you eat then bypasses much of the small
intestine, resulting in fewer calories absorbed and weight loss.
