choledochojejunostomy
Pronunciation: /koʊ.liː.doʊ.koʊ.dʒɪ.dʒuː.nɒs.toʊ.mi/
Surgical connection between the common bile duct and jejunum to restore biliary drainage.
Full Definition
A surgical anastomosis that connects the common bile duct (choledochus) directly to a loop of jejunum, bypassing the duodenum and pancreatic duct. This procedure is commonly performed in pediatric patients with biliary atresia, choledochal cysts, or other conditions requiring biliary reconstruction. The technique involves creating a Roux-en-Y limb of jejunum that is brought up to the porta hepatis for anastomosis. Success depends on adequate bile duct size and the absence of cirrhosis. Long-term complications may include cholangitis, anastomotic stricture, or malignancy.
Usage
Usage note: Often used interchangeably with hepaticojejunostomy in pediatric contexts.
