摘要
Hepatobiliary manifestations are common in inflammatory bowel disease(IBD),with 30%of patients presenting abnormal liver tests and 5%developing chronic liver disease.They range from asymptomatic elevated liver tests to lifethreatening disease and usually follow an independent course from IBD.The pathogenesis of liver manifestations or complications and IBD can be closely related by sharing a common auto-immune background(in primary sclerosing cholangitis,IgG4-related cholangitis,and autoimmune hepatitis),intestinal inflammation(in portal vein thrombosis and granulomatous hepatitis),metabolic impairment(in non-alcoholic fatty liver disease or cholelithiasis),or drug toxicity(in drug induced liver injury or hepatitis B virus infection reactivation).Their evaluation should prompt a full diagnostic workup to identify and readily treat all complications,improving management and outcome.
