Biliopancreatic Diversion

This procedure is similar to the gastric bypass in its complexity.  Like the gastric bypass part of the small intestine is bypassed.  In this procedure part of the stomach is removed.  The remaining stomach is hooked up to a part of the small intestine further down towards the colon.  As much as, 90 per cent of the small intestine is bypassed resulting in significantly less malabsorption, which means fewer calories and nutrients are absorbed.  The stomach has become smaller so much less food can be held there (approximately 1 cup full). 

Biliopancreatic Diversion is recommended for those who have a large amount of weight to lose because it is so effective.  It is also suitable for those who have trouble controlling their portions as because of the bypassing of the small intestine does not allow malabsorption. 

Even though this procedure involves the bypassing of the small intestine and therefore uses the malabsorption method of weight loss, dumping does not occur as frequently.  Unlike the gastric bypass where dumping syndrome is very common.
