There are many causes of cholestasis.
Extrahepatic cholestasis -- which occurs outside the liver -- can be caused by bile duct tumors, strictures, cysts, diverticulitis, and other damage. Other potential causes for this type include stones in the common bile duct, pancreatitis, pancreatic tumor or pseudocyst, primary sclerosing cholangitis, and compression due to a mass or tumor on a nearby organ. Other causes may exist.
Intrahepatic cholestasis -- which occurs inside the liver -- can be caused by sepsis, bacterial abscess, drugs, being fed by an IV, lymphoma, tuberculosis, sarcoidosis, and amyloidosis. Other causes of this form of the disorder include primary biliary cirrhosis, primary sclerosing cholangitis, viral hepatitis, alcoholic liver disease, pregnancy, Sjogren syndrome, and others.
