Kocher maneuver
Pronunciation: KOH-kher ma-NOO-ver
A surgical technique involving mobilization of the duodenum and pancreatic head by dividing lateral peritoneal attachments.
Full Definition
The Kocher maneuver is a fundamental surgical technique used in hepatobiliary and pancreatic surgery to achieve wide exposure of retroperitoneal structures. The maneuver involves incision of the lateral peritoneal reflection of the duodenum and mobilization of the duodenum and pancreatic head from the retroperitoneum in a medial direction. This technique provides access to the inferior vena cava, aorta, left renal vein, and allows assessment of tumor resectability in pancreatic cancer surgery. Proper execution of the Kocher maneuver is essential for safe performance of pancreaticoduodenectomy and enables evaluation of superior mesenteric artery and vein involvement. The maneuver also facilitates control of bleeding from posterior duodenal injuries.
Usage
Usage note: Capitalize 'Kocher' as an eponym. Can be used as verb: 'to Kocherize' the duodenum.
