Duodenal switch
A complex bariatric procedure involving sleeve gastrectomy combined with biliopancreatic diversion, relevant in gastrointestinal oncology for metabolic considerations.
Full Definition
Duodenal switch is a malabsorptive bariatric surgical procedure that combines a sleeve gastrectomy with a biliopancreatic diversion. The procedure involves transecting the duodenum beyond the pylorus and creating an anastomosis between the distal small bowel and the duodenal stump, while diverting biliopancreatic secretions to the distal ileum. In gastrointestinal oncology contexts, this procedure is relevant when considering surgical options for obese patients with gastric or pancreatic malignancies, as it affects nutrient absorption and may influence perioperative management and long-term surveillance strategies.
