What are the risks of the duodenal switch?
A. The short-term surgical risks of duodenal switch are similar to those of gastric bypass. These include the risk of bleeding, infection and leakage of gastrointestinal contents. These complications may require a return to the operating room for repair. Additionally, because of the amount of malabsorption it causes, the duodenal switch may result in more long term nutritional complications than other procedures. For this reason it is necessary to have lifelong nutritional follow-up after duodenal switch.
