The Biliopancreatic Diversion with Duodenal Switch – abbreviated as BPD/DS – involves two procedures as part of the surgery. First, a smaller, tubular stomach pouch is created by removing a portion of the stomach, which is a similar to the sleeve gastrectomy surgery. The second procedure involves bypassing a major portion of the small intestine so that food can be redirected to the end of your small intestine.
The bypassed small intestine, which carries the bile and pancreatic enzymes that are necessary for the breakdown and absorption of protein and fat, is reconnected to the latter portion of the small intestine so that these enzymes can eventually mix with the food stream. BPD/DS initially helps by reducing the amount of food that is consumed; however, over time people who have the procedure are able to consume near “normal” amounts of food.
Additionally with this procedure food does not mix with the bile and pancreatic enzymes until further down the small intestine. This results in a significant decrease in the absorption of calories and nutrients (particularly protein and fat) as well as nutrients and vitamins dependent on fat for absorption (fat soluble vitamins and nutrients).
BPD/DS affects gut hormones in a manner that impacts hunger and satiety as well as improving blood sugar control. The BPD/DS is considered to be the most effective surgery for the treatment of diabetes.
BPD/DS allows a patient to lose more weight than the other three more common types of bariatric surgery. Studies have shown that people who have this procedure experience 60 to 70 percent excess weight loss or greater at the five-year mark following surgery.
The BPD/DS surgery can have more complications that result due to the complexity of the surgery. It can also cause a shortage of vitamins, minerals and protein that your body needs to be healthy.
Patients who have the following conditions are not ideal for this surgery.
What to expect following the surgery - Recovery can take two to four weeks on average depending on overall health condition, job restrictions and patient compliance to post-operative instructions.
