title: Biliary bile acids in the gall-bladder and the common bile duct of patients with anomalous pancreaticobiliary ductal junction.
abstract: The high incidence of biliary tract carcinoma in patients with anomalous pancreaticobiliary ductal junction (APBDJ) with or without choledochal cyst (CC) has been well documented. Twenty-two patients with APBDJ were divided into three groups: Group A, four patients not associated with CC and biliary tract carcinoma; Group B, 13 patients with CC but without biliary tract carcinoma; and Group C, five patients with biliary tract carcinoma (four with and one without CC). Profiles of bile acids in the gall-bladder and/or common bile duct were analysed in these patients and compared with those in the control patients with cholecystlithiasis to examine the hypothesis that the levels of deoxycholic acid (DCA) and lithocholic acid (LCA) are elevated in patients with APBDJ because these secondary bile acids are mutagenic. Bile acids were quantified by gas-liquid chromatography. Total bile acid concentration in the gall-bladder bile was significantly lower in any group with APBDJ than that of controls. In the gall-bladder, increased proportion of chenodeoxycholic acid (CDCA) in Group A and B, decreased proportion of DCA in Group B and increased proportion of cholic acid (CA) in Group C were found in bile. In the bile duct, total bile acid concentration and proportion of DCA were significantly low in bile from Group C and decreased proportion of DCA and increased proportion of CDCA were found in bile from Group B. In both the gall-bladder and hepatic bile, proportion of LCA was not significantly different between any intergroups.(ABSTRACT TRUNCATED AT 250 WORDS)
