[Differential diagnosis between the cholestatic form of viral hepatitis and tumor-caused obstructive jaundice]

An analysis of findings of laboratory examinations of 36 patients with a cholestatic form of virus hepatitis and 35 patients with carcinoma of the hepatopancreatoduodenal zone enabled the authors to establish the differential-diagnostic significance of the activity of gamma glutamyl transpeptidase, time of plasma recalcification, plasma tolerance to heparin, fibrinogen content in plasma and fibrinolytic activity in cholestatic hepatitis and mechanical jaundice.
