The duodenal switch procedure is a form of biliopancreatic diversion which is often done as an obesity reduction surgery.

It has a restrictive portion and malabsorptive portion:

restrictive portion: involves removal of approximately 70% of the stomach (along the greater curvature) and most of the duodenum
malabsorptive portion: involving rerouting a lengthy portion of small bowel creating two separate pathways and one common channel

History and etymology

It is thought to have been described by DeMeester and colleagues in 1987 as a surgical solution for primary bile reflux gastritis or to decrease the postgastrectomy symptoms seen in patients after distal gastrectomy and gastroduodenostomy.
