Overview
Etiology
- Gallstones
- Abdominal mass (e.g. cancer)
- Primary sclerosing cholangitis, secondary to inflammatory bowel disease
- Primary biliary cirrhosis, secondary to autoimmune disorders
- Congenital anomalies of the bilary tract
- Biliary trauma
- Some drugs, (e.g. Flucloxacillin and Erythromycin)
- In children, biliary atresia and other pediatric liver diseases
- Pregnancy, referred to as Intrahepatic Cholestasis of Pregnancy, or Obstetric Cholestasis
Histopathology
Under a microscope, the individual hepatocytes will have a brownish-green stippled appearance within the cytoplasm, representing bile that cannot get out of the cell. Canalicular bile plugs between individual hepatocytes or within bile ducts may also be seen, representing bile that has been excreted from the hepatocytes but cannot go any further due to the obstruction. When these plugs occur within the bile duct, sufficient pressure (caused by bile accumulation) can cause them to rupture, spilling bile into the surrounding tissue, causing hepatic necrosis. These areas are known as bile lakes, and are typically seen only with extra-hepatic obstruction.
Symptoms
Bile is secreted by the liver to aid in the digestion of fats. Drugs such as gold salts,nitrofurantoin, anabolic steroids, chlorpromazine, prochlorperazine, sulindac, cimetidine, erythromycin, can cause cholestasis and may result in damage to the liver.
