Lap Biliopancreatic Diversion
These operations combines removal or exclusion of 2/3rds of the stomach along with a long intestinal bypass which significantly reduces the absorption of fat. The capacity to eat is greater than with the other operations, and the eventual weight loss is the best of all the operations but if fatty foods are overeaten e.g. a hamburger and fries then diarrhoea and foul flatus will result.
