Abstract    Objective    To investigate the experience of treatments of long-term postoperative complications in congenital choledochal cyst (CCC).  Methods    Retrospective analysis of the clinical data of postoperative patients with long-term complications in 48 cases of CCC patients from January 1999 to December 2008 in Shengjing hospital of China Medical University.  Results    The long-term postoperative complications of CCC mainly included 31 cases of biliary lithiasis, 25 cases of repeated cholangitis, 16 cases of stoma stenosis, 3 cases of cyst cancerization. The reoperative methods included complete cyst excision and Roux-en-Y hepatojejunostomy in 28 cases, excision of hepatojejunostomy and reanastomosis in 7 cases, biliary duct exploration and calculus removed in 3 cases, biliary duct exploration and hepatic segment excision in 3 cases, cyst excision and pancreatoduodenectomy in 1 case. 6 cases of stoma stenosis and/or intrahepatic calculus were managed by percutaneous transhepatic cholangioscopy (PTCS).  Conclusions    The long-term postoperative complications of CCC are usually correlated with inappropriate initial operation. In order to prevent the complications of reoperation, the aims for treatment should include cyst excision, calculous focus removing, obstruction disengage, biliopancreatic shunt, and biliary drainage unobstruction.
