Kocher maneuver
Pronunciation: KO-kher
Surgical technique involving mobilization of the duodenum by dividing its lateral peritoneal attachments.
Full Definition
A fundamental surgical maneuver that involves dividing the lateral peritoneal attachments of the duodenum and reflecting it medially to expose the retroperitoneal structures. Named after Emil Theodor Kocher, this technique provides essential exposure during pancreaticoduodenectomy, allows assessment of pancreatic head tumors for resectability, and enables evaluation of the posterior pancreatic head margin. The maneuver also facilitates control of retroperitoneal bleeding and improves visualization during complex hepatobiliary procedures.
Usage
Usage note: Always capitalize 'Kocher' as it derives from the surgeon's name; apostrophe usage varies.
