Duodenal Switch Surgery

The duodenal switch procedure is commonly referred to as BPD/DS surgery, as it is a combination of the biliopancreatic diversion with a duodenal switch. This hybrid procedure was first developed in the 1980's, and although it is a less common procedure, the reported results of this procedure are among the best long term weight loss outcomes available. This operation is a combination restrictive and malabsorptive surgery. Weight loss occurs as a result of both eating less food and a reduction in the absorption of the caloric content of that intake. BPD/DS surgery is a highly effective weight loss procedure with a very low risk of significant weight regain.

How is Deuodenal Switch Surgery Different?
In a BPD/DS procedure about 70% of the stomach is removed and the intestinal tract is "switched" around to alter the digestion and absorption of food intake. Rather than connecting a small pouch at the entrance to the stomach to the lower intestine, in a duodenal switch, the connection is made at the exit of the stomach just below teh pyloric valve.

Advantages of BPD/DS
In comparison to the gastric bypass, patients are able to eat more food after a duodenal switch operation. In addition, dumping syndrome is not a side effect as the pyloric valve, which connects the stomach to the small intestine is left intact. As a result, a duodenal switch procedure usually leads to the most satisfaction on the part of the patient.


Disadvantages of BPD/DS
Duodenal switch surgery is one of the most complicated types of bariatric surgery, so only the most experienced of weight loss surgeons should perform this operation. As it is a malabsorptive procedure the intestinal change can lead to soft stools which can last for months to an indefinite amount of time. There is also an increased risk of gallstones or gall bladder problems. As with all surgical procedures, make sure to consult with a surgeon to see if this procedure is right for you.


How Does it Work?
In BPD/DS surgery the stomach is vertically divided and about 80% of the stomach is removed leaving a banana shaped pouch. Unlike in a Roux-en-Y gastric bypass, a duodenal switch procedure leaves the digestive functioning of the stomach in place. The pyloric valve, which regulates the release of the stomach contents into the small intestine, is left in place.

The small intestine is then rerouted, creating two pathways and one common channel. The shorter pathway, called the digestive loop, connects the stomach to the common channel. The larger of the pathways is called the biliopancreatic loop, which carries bile from the liver down to the common channel. The common channel is the part of the small intestine where the food and bile mix before being emptied into the large intestine. The purpose of this arrangement is to limit the body's ability to absorb fat from food.

Following BPD/DS surgery the body's release of hormones in the digestive process is unchanged. One of the advantages of this is that dumping syndrom is less of a problem.
