What is Duodenal switch operation?
BPD is now modified and includes 2 parts – Restrictive and Malabsorption. 1st part is Sleeve Gastrectomy taking out ¾ of stomach and the 2nd part is the duodenal switch i.e. the distal bypass. These 2 parts can be staggered so that one can have Sleeve Gastrectomy first and then duodenal switch 6 – 18 months later, reducing the risks operation considerably.
