Choledochojejunostomy
Pronunciation: ko-LED-oh-ko-jeh-joo-NOS-toh-mee
A surgical anastomosis between the common bile duct and jejunum to restore biliary drainage.
Full Definition
Choledochojejunostomy is a biliary-enteric anastomosis that creates a direct connection between the common bile duct and a loop of jejunum, bypassing obstructed or damaged portions of the distal biliary tree. This procedure is commonly performed for benign biliary strictures, bile duct injuries, or as part of complex hepatobiliary reconstructions. The anastomosis can be constructed in an end-to-side or side-to-side configuration, often with a Roux-en-Y jejunal limb to prevent reflux. Success depends on adequate bile duct diameter, healthy tissue, and tension-free anastomosis. Long-term patency rates are excellent, though complications may include anastomotic stricture, cholangitis, or bile leak.
Usage
Usage note: Specify anastomotic configuration and whether Roux-en-Y reconstruction was used.
