Duodenal Switch

Duodenal switch is a surgical operation that combines features of both gastric sleeve surgery and gastric bypass. The procedure is performed in two steps. Firstly, 80% of the stomach is removed and the rest of the stomach is turned into a tube. This procedure is referred to as gastric sleeve surgery. In the next step, the small intestine, which is normally connected to the stomach, is separated to form a bypass and two separate pathways and a canal are created. In this way, the food taken goes first to the tube stomach, then to the lower part of the small intestine, not to the beginning of the small intestine, and from there to the large intestine.

Duodenal switch surgery prevents patients from feeling hunger and reduces their appetite, because in this procedure, the part of the stomach that produces hunger is removed.

To whom is duodenal switch surgery performed?

It is the most effective bariatric surgery for patients defined as super obesity patients with a body mass index of 50 and above. In addition, duodenal switch surgery is recommended for people who have not reached the desired weight loss despite having undergone gastric sleeve surgery before and for people with uncontrolled diabetes. Duodenal Switch is also the most effective procedure for weight loss in patients with high blood pressure and cholesterol.

Are There Side Effects of Duodenal Switch Surgery?

In duodenal switch surgery, dumping syndrome does not occur because the outlet muscle called pylorus, which controls the emptying of the stomach, is not intervened.

With this procedure, absorption in the stomach decreases, so patients experience more frequent and loose bowel movements. Therefore, it is important to monitor the vitamin, mineral and protein levels of the patients.

Is There a Possibility of Weight Gain After Duodenal Switch Surgery?

After the duodenal switch surgery, there is no need to apply any diet programme for the patient.  Since the absorption of fats is restricted with the surgery, patients are recommended to consume foods with high fat content. With Duodenal Switch surgery, super obesity patients do not need to change their lifestyle. They can continue their lives without gaining weight for a lifetime. Therefore, patients can lose 60-80 per cent of their weight within 2 years by this method.
