[Diagnostic value of serum total bile acid in hepatobiliary diseases].

The purpose of this study was to evaluate the clinical diagnostic value of serum total bile acid (STBA) in hepatobiliary diseases. Fasting STBA was measured using the enzymatic colorimetric method in 44 normal control cases and 153 cases of hepatobiliary disease, and then abnormal rates were compared to other conventional liver function tests. These 153 cases of hepatobiliary diseases included acute viral hepatitis (10 cases), chronic persistent hepatitis (32 cases), chronic active hepatitis (16 cases), liver cirrhosis (15 cases), alcoholic hepatitis (11 cases), alcoholic fatty liver (23 cases), alcoholic cirrhosis (17 cases), chronic liver diseases with slight fatty changes (10 cases) and hepatocellular carcinoma (6 cases). Except for 8 cases of acute viral hepatitis, the above cases were verified by liver biopsy. There were also 13 cases of biliary tract diseases. Fasting STBA and other conventional liver function tests were used in the above hepatobiliary diseases during the acute, exacerbated or decompensated stage, and the stable or compensated stage, and their abnormal rates compared. The results of this study revealed that the concentration of STBA is raised in various hepatobiliary diseases, which is related to the degree of hepatic cell injury and the various stages of liver. The concentration of STBA was higher in the acute, exacerbated or decompensated stage than in the convalescent, stable or compensated stage of liver diseases. When the abnormal rates of STBA were compared to other conventional liver function tests, the abnormal rates of STBA were not inferior to r-GT, GOT and GPT, and were more accurate than the other liver function tests.(ABSTRACT TRUNCATED AT 250 WORDS)
