Biliopancreatic Diversion/Duodenal Switch

A biliopancreatic diversion with duodenal switch (BPD/DS) is a bariatric procedure that involves two major steps. First, a smaller, tubular stomach pouch is created by removing a portion of the stomach, very similar to the sleeve gastrectomy. Next, a large portion of the small intestine is bypassed. This is a less common weight loss procedure that limits the amount of food eaten by a patient and reduces the abortion of nutrients, including fats and proteins. 

How It Works

A biliopancreatic diversion changes the normal process of digestion by making the stomach smaller. It allows food to bypass part of the small intestine so that you absorb fewer calories. This surgery is for super obese people who haven’t been able to lose weight any other way. Super obesity means that you have a BMI (body mass index) of 50 or higher. 

Results

Because the surgery makes your stomach smaller, you will get full more quickly when you eat.  It Allows patients to eventually eat near “normal” meals as it reduces the absorption of fat by 70 percent or more. Biliopancreatic Diversion/Duodenal Switch causes favorable changes in gut hormones to reduce appetite and improve satiety.
