[Cholestasis in total parenteral nutrition. A review].

Intrahepatic cholestasis is a frequent, however, unresolved complication of total parenteral nutrition in infancy. A frequency of 10-50% is reported. The concentration of serum bile acids seems to be a sensitive indicator for a beginning cholestasis. As typical histological alterations of the liver are considered: inflammatory portal reaction, fibrosis and proliferation of bile ducts. As important components of the obviously multifactorial etiology are considered: lacking oral alimentation, fetal bile acid synthetic pathways, amino acid toxicity, hypoalbuminemia, sepsis and substrate excess.
