Biliopancreatic Diversion Surgery

Biliopancreatic diversion surgery is one of the many types of weight loss operations. A BPD procedure is both a restrictive and malabsorptive surgery, leading to weight loss through reduced food intake and absorption. This surgery is also called the Scopinaro procedure as it was first preformed by Nicola Scopinaro in Italy in 1979.

The biliopancreatic diversion surgery was first devised to reduce the health complications associated with the discontinued jejuno-ileal bypass procedure. The BPD procedure is generally now performed with a duodenal switch as well, although both procedures are much less common than a gastric bypass. The procedure is popular with patients though, as they can eat larger quantities of food than with other restrictive procedures.

How is Biliopancreatic Diversion Surgery Different?
Similar to the Roux-en-Y gastric bypass, biliopancreatic diversion is both a restrictive and malabsorptive procedure. Unlike the gastric bypass, the BPD technique requires removal of about 70% of the stomach. This is done to decrease the quantity of acid produced by the remaining stomach. In addition, BPD leaves the patient with a much larger stomach pouch than a gastric bypass, thus allowing patients to eat a larger volume of food before feeling full.

Advantages of Biliopancreatic Diversion
BPD is effective for extremely obese patients, generating results of increased weight loss over a gastric bypass. BPD has been shown to deliver weight loss of 60-80% of excess body weight. In comparison a gastic bypass averages 50-70% of excess weight loss. The ability for greater food consumption sometimes leads to increased satisfaction in patients. In addition, patients may experience less food intolerance post operation.


Disadvantages of BPD
Long term medical follow up and attention is required after a biliopancreatic diversion. Nutritional deficiencies are common and many patients need to take nutritional supplements for the rest of their life. If not properly monitored, this can lead to malnutrition and anemia. These are medical issues that can be controled, although the increased level of monitoring has led surgeons to make this a less common procedure.


How Does it Work?
To restrict the intake of food, about 80% of the stomach is removed from the body. The remaining stomach is then connected to the lower (distal) part of the small intestine. Through reducing the amount of the small intestine that food passes through, the body's ability to absorb nutrients is reduced and leads to weight loss. In total, about nine feet of the small intestine is bypassed in this process.

The remaining stomach pouch is about two to three cups in size, or about the size of a soda can. Eventually the stomach can stretch and return to its original size.

How is it Different From a Duodenal Switch?
The main difference between biliopancreatic diversion surgery and a duodenal switch procedure is the part of the stomach that is removed. In BPD/DS, the left side of the stomach is taken out, while in a BPD procedure it is the lower part of the stomach that is extracted.
