Laparoscopic Duodenal Switch

Duodenal switch is a malabsorptive procedure that consists of a combination of sleeve gastrectomy and biliopancreatic diversion. The mechanism of weight loss after the duodenal switch is due to restriction caused by sleeve gastrectomy and malabsorption due to reduction of the functional shortening capacity of the small bowel reduces the absorption capacity. The common channel is usually 75–150 cm long. The long-term results of this technique are very good with high percentages of comorbidity reduction and weight loss. In this chapter, the laparoscopic duodenal switch will be described step by step.
