Kocher maneuver
Pronunciation: KOH-ker
Surgical mobilization technique involving division of lateral peritoneal attachments to rotate the duodenum and pancreatic head medially.
Full Definition
The Kocher maneuver is a fundamental surgical technique that involves division of the lateral peritoneal attachments (white line of Toldt) along the second portion of the duodenum to allow medial rotation and mobilization of the duodenum and pancreatic head. This maneuver exposes the inferior vena cava, aorta, and left renal vessels, providing access to the retroperitoneum. The technique is essential for adequate exposure during pancreaticoduodenectomy, duodenal trauma repair, and exploration of retroperitoneal hematomas. Proper execution requires careful identification of anatomical planes to avoid injury to retroperitoneal structures.
Usage
Usage note: Named surgical technique; capitalize 'Kocher' as proper noun.
