OBJECTIVE: To study the relationship between anomalous junction of pancreaticobiliary duct (APBD) and congenital bile-duct cystic as well as cylindrical dilatation.
METHOD: Cholangiography was performed in 51 patients with bile-duct dilatation.
RESULTS: APBD was diagnosed in 43 patients. In 8 patients (72%), the bile duct was drained into the pancreatic duct (B-P) in the cystic group, whereas in 14 patients (78%), the pancreatic duct was drained into the bile duct (P-B) in cylindrical group. There were significant differences in the internal diameter of the distal bile duct (P < 0.01), the maximal diameter of the pancreatic duct (P < 0.05) and the average angle of pancreaticobiliary junction (P < 0.01) in cystic and cylindrical groups.
CONCLUSIONS: Different types of APBD after lead to different pathological changes of the biliary tract. The narrowed distal bile duct joins the pancreatic duct at a right angle in most cystic cases and the pancreatic duct joins the bile duct at an acute angle in most cylindrical cases.
