Malabsorptive obesity surgery.

ABSTRACT

Biliopancreatic diversion is the only valuable surgical approach for changing intestinal absorption. It is efficient in producing appropriate permanent weight loss and has a considerable psychological advantage because it does not impose abnormal food restriction. It not only decreases caloric absorption, but it also directly improves insulin and lipid metabolism. The ideal technique for the construction of BPD is not yet established, but our current preference is for the duodenal switch type. BPD must be seen as a means to change an intolerable and untreatable disease to a tolerable and treatable one, with substantial improvement in quality of life.
