title: Double common bile duct with choledochal cyst and cholelithiasis: report of a case.
abstract: Double common bile duct (DCBD) is a rare congenital anomaly of the biliary system, often associated with biliary lithiasis, choledochal cyst, pancreaticobiliary maljunction (PBM), and upper gastrointestinal tract malignancies. We report a case of type I DCBD with choledochal cyst and cholelithiasis in a 52-year-old Chinese man. We also reviewed 24 cases of DCBD reported in the Chinese literature between 1965 and 2012. Most (58.3%) of these cases were classified as type I DCBD, with accompanying choledocholithiasis in 79.2%, cholecystolithiasis in 37.5%, choledochal cyst in 33.3%, and PBM in 8.3%. There was no case of concomitant cancer. The type and coexistence of PBM with DCBD are clinically important because of its close implications with concomitant pathology. Most Chinese people with DCBD have type I. Moreover, the high incidences of choledochal cyst and biliary lithiasis and the extremely low incidences of PBM and biliary cancer are the major clinical characteristics of DCBD in China.
