A biliopancreatic diversion is a lesser-known weight-loss procedure. It is generally a single-step procedure but can involve two steps in selective situations. The first step is the removal of a significant portion of the stomach called sleeve gastronomy, and the second step is an intestinal bypass. A biliopancreatic diversion limits food consumption and reduces the absorption of nutrients, proteins and fats. Although the procedure is effective, it involves more risk: vitamin deficiencies and malnutrition. The procedure is recommended only for people with BMI above 50.
- Alternate Name
Biliopancreatic with duodenal switch
- Body Location:
Stomach and small intestine
- How Performed:
It’s done laproscopically with small holes in abdomen
Step 1: Sleeve gastrectomy - This involves removal of about 80 percent of the stomach, leaving behind a banana-shaped tube stomach, pyloric valve( transferring food to the small intestine) and duodenum.
Step 2: Intestinal bypass - This involves bypassing the intestine by linking the end portion of the intestine to the initial small portion of the intestine, the duodenum.
