Abstract
|
|
|
The recommended surgical method for treating congenital biliary dilation is excision of the entire extrahepatic bile duct, with a hepaticoenterostomy to stop reflux and stasis of pancreatic secretions in the gallbladder and dilated bile duct. Late complications of surgical treatment include anastomotic strictures, cholangitis, and stone formation in the intrahepatic bile ducts. This report describes a very rare late complication, in which protein stones formed in a remnant choledochal cyst in the pancreas 23 years after resection of a congenital choledochal cyst. Our case highlights the necessity for complete cyst resection as close as possible to the portion buried in the pancreatic bed at the time of primary choledochal cyst resection.
