Cholestasis and alcoholic liver disease.
Histologic cholestasis and clinical jaundice may be seen in all stages of alcoholic liver disease. In rare cases, isolated cholestasis without significant steatosis, hepatitis, or cirrhosis is identified in an alcoholic patient. The mechanisms of ethanol-induced cholestasis are not well studied but may involve compression of intrahepatic biliary radicals or interference with basolateral uptake and intracellular transport of bile acids. In the evaluation of the jaundiced alcoholic patient, clinical, biochemical, and radiologic data are usually sufficient to distinguish alcohol-induced liver disease from extrahepatic biliary obstruction. In cases where the diagnosis is not readily apparent, more invasive studies such as liver biopsy or ERCP may be necessary. The risk of these invasive studies is directly related to the degree of underlying hepatic dysfunction.
