The duodenal switch is an operation that temporarily restrict the stomach capacity to give initial weight loss and by the time the stomach dilates and patients eat more the second part of the operation which is malabsorption helps the patient to maintain the lost weight. The principle of using sleeve gastrectomy alone was postulated in extremely obese patients to make the first operation easy and complete the second part of the operation after achieving some weight loss.
