13 May 2019 Biliopancreatic diversion by Scopinaro’s procedure was developed in the late 1970s to maintain function of all the small intestine segments , thereby reducing some problems reported in other, older techniques. This procedure involves: A reduction in gastric volume, with removal of the lower part of the stomach; Connection of the remaining stomach pouch to the end of the small intestine or ileum. The duodenum and jejunum, where an important part of the digestion and absorption process takes place, are bypassed. This removes these segments of the intestine from the process. They now only carry biliary and pancreatic secretions and release them into the final portion of the ileum. The fact that the pylorus is removed slows down the gastric emptying rate. Some patients experience dumping syndrome after this operation, mainly due to intake of foods with a high fat and / or sugar content, mainly through: Asthenia; Nausea; Sweating; Diarrhoea. However, these symptoms help patients to eliminate high-calorie foods from their diet.
