Bile acid pattern of gallbladder and hepatic bile in patients with and without cholesterol gallstones
Abstract:
Bile acid composition of hepatic and gallbladder bile was examined in a group of 18 patients with uncomplicated cholelithiasis and a control group consisting of 13 patients with healed duodenal ulcers. Bile specimens were taken during laparotomy. Molar concentrations of the different bile acids in hepatic and gallbladder bile were determined. The ratios between the molar concentrations of the different bile acids were calculated. In order to compare these molar ratios in hepatic and gallbladder bile the quotients between identical molar ratios of hepatic and gallbladder bile were calculated in each subject. Bile acid concentration of the gallbladder bile was found to be lower in the gallstone patients. Trihydroxy or dihydroxy bile acid molar ratio was lower in the gallstone group. Hepatic to gallbladder relative trihydroxy to dihydroxy and cholate to deoxycholate bile acid ratios were elevated in the gallstone patients. This might indicate that an increased formation of deoxycholate is the main cause for the decreased trihydroxy to dihydroxy bile acid molar ratio observed in the gallbladder bile of patients with cholesterol gallstones.
