BPD is a surgery for obesity in which a large part of the lower stomach is removed and the small part of stomach that is left is connected directly to the last part of the small intestine (jejunum).  After a BPD, the stomach size is usually larger than with gastric bypass. Unlike in gastric bypass where the excluded stomach is left in place, the BPD involves a removal of a variable volume of the organ. Further, the bypass of the small intestine is much longer than in a standard roux-en-y gastric bypass, leaving only a short segment of small bowel exposed to the mix of nutrients and bile. This significantly reduces absortion of nutrients and contributes to the profound weight loss effect of the procedure. On the other hand, it is associated with a greater risk of nutritional side effects. At NewYork-Prebyterian the procedure is performed in its technical variant called BPD-Duodenal Switch, to reduce some of the potential side effect of the classic BPD.
