Biliopancreatic diversion (duodenal switch procedure)

The physiological principle underlying biliopancreatic diversion (BPD) is a ttractive. It decreases food absorption and particularly that of fat. It pr eserves normal eating habits and is compatible with a good quality of life. Because weight loss is not a function of an imposed aversion to eating, it is more appealing to patients. Data are accumulating showing that BPD can permanently cure morbid obesity in a majority of patients and is remarkably well tolerated. While long-term systemic side-effects from decreased absor ption continue to raise concerns, available results have already shown that , within 20 years, metabolic disturbances are well tolerated while weight l oss and quality of life are maintained. Vitamin and mineral replacement the rapy and periodic monitoring are essential. The original procedure describe d by Scopinaro with subsequent modifications will be presented, focusing on the duodeno-ileal switch procedure. (C) 1999 Lippincott Williams & Wilkins .
