Re: Duo switch v Biliopancreatic Diversion-

The basic difference between the 2 surgeries is that the classic BPD

bypasses the pyloric valve and the DS keeps the pyloric valve intact and

functioning. The intestinal bit is the same in both. The pyloric valve is

the valve at the bottom of the stomach that regulates the release of food

into the intestine. If it is bypassed, food will enter the intestines as

soon as it hits the stomach and not be regulated by anything. Both

surgeries are effective with regards to long term weight loss. The

difference is merely in the way food hits the intestine after leaving the

stomach.

Let me know if you need further clarification, OK? Take care!
