Often obvious hepatomegaly, skin (wide fleas) itch. Liver function test serum bilirubin was significantly elevated to direct bilirubin, manifested as obstructive jaundice. Such as alkaline phosphatase, γ-transpeptidase, cholesterol were significantly elevated serum transaminase moderate increase, and turbidity test no change. Obstructive jaundice for more than 3 weeks, and except for other extrahepatic and obstructive jaundice (including drug-induced, etc.) who can be diagnosed as the disease.
