Duodenal Switch, also known as biliopancreatic diversion surgery, which highly prevents absorption and partially limits the volume, is applied to super obese people.
It is a surgical procedure performed in patients whose body mass index is over 50 and who have previously undergone sleeve gastrectomy operation but gained all the weight again. It can also be performed for uncontrolled diabetes situations.
The surgery is performed with the laparoscopic method. In this operation, sleeve gastrectomy is performed first, the stomach size is reduced and then the last 200-250 cm of the small intestine is anastomosed by counting from the section close to the large intestine. Thus, food is directly directed to the small intestine. A strong malabsorption and absorption restriction is created in a way to bypass about 2/3 of the small intestine. In other words, the main effect of the operation is to create weight loss by using the power of metabolic activity. As in all other absorption-destructive procedures, since absorption is excessively impaired; burping, abdominal pain, undigested food and related odorous diarrhea that may disrupt life comfort can be seen. Patients should consume high protein since protein absorption is disrupted. These patients suffer from serious vitamin deficiency and anaemia. This operation is performed quite successfully both in our country and around the world.
