Its a procedure similar to a gastric bypass. It involves creating a small stomach pouch then rerouting the intestines. The procedure has several advantages and some disadvantages. In this procedure, surgeons create a small stomach and rest of stomach removed. The small bowel is then divided into two parts. The end of the small bowel is connected to the stomach so that food passes directly from the small stomach to it and the bypassed piece that contains bile and important digestive enzymes connected to last part of the ileum. Food and the enzymes will meet in this area where digestion takes place. The patients thus digest efficiently and eat less food. This leads to weight loss and correction of metabolic syndrome.
