Biliopancreatic diversion with duodenal switch (BPD/DS) causes favorable changes in gut hormones in a way that impacts hunger and satiety as well as improves a patient’s blood sugar control. BPD/DS is considered to be the most effective surgery for the treatment of diabetes compared to other bariatric surgery options.
Biliopancreatic diversion with duodenal switch involves two procedures. First, a smaller, tubular stomach pouch is created by removing a portion of the stomach, 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 the 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 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 are able to consume near “normal” amounts of food.
Also, since food does not mix with the bile and pancreatic enzymes until further down the small intestine, there is 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 allows a patient to lose more weight than other 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 after surgery.
BPD/DS surgery can have complications due to the complexity of the surgery. It can also cause a shortage of vitamins, minerals and protein that the body needs to stay healthy. Potential concerns include:
If you have these conditions, this surgery may not be right for you:
Recovery can take two to four weeks on average depending on a patient’s overall health condition, job restrictions and patient compliance to post-operative instructions.
