The study comprised surgical patients presenting with tumours of the extrahepatic biliferous ducts. The above patients revealed a high activity of gamma-glutamyltransferase, alkaline phosphatase at the expense of the hepatic isoenzye, to a lesser extent--of asparaginaminotransferase, alaninaminotransferase, a high level of conjugated bilirubin, an insignificant increase in the level of cholesterol and triglycerides. The above biochemical indices combined with results of other methods of investigation can be used for early diagnosis of mechanical jaundice of the tumour genesis.
