    Abstract:
    Parenteral nutrition associated cholestasis in preterm infants and newborn children is a frequent and serious disease with an incidence of 23% depended on duration of parenteral nutrition and birthweight. The incidence of liver cirrhosis is 40% when parenteral nutrition is given 74-242 days. The pathogenesis remains unclear. Several predisposing factors are discussed like immaturity, lack of hormonal stimulation by oral feeding, bacterial infection, liver toxicity of aminoacids and their products of photooxidation, lack of taurine, lack of antioxidation substances, hypermanganesaemia and pollution of infusion solutions. Furthermore sepsis during parenteral nutrition seems to multiply the risk of cholestasis. For prevention controlled studies recommend: 1. Early enteral nutrition. 2. The reduction of parenteral amino acids to less than 3 g/kg/d. 3. Light protection for parenteral solutions. 4. Cyclic infusion of parenteral nutrition. 5. The application of antibiotics (metronidazole, gentamicin) during parenteral nutrition. The most important therapeutic intervention is the beginning of oral feeding. Most of the time this leads to a decrease of icterus within two weeks. An icterus persisting longer than 3 weeks should be treated because of the risk of liver cirrhosis. Further therapeutic interventions are: 1. Cholecystokinin, good results in case studies which still has to be verified by a controlled study. 2. Ursodeoxycholic acid, its choleretic effectiveness is verified in several liver diseases by controlled studies, but it is not proven in parenteral nutrition associated cholestasis. 3. Laparoscopic biliary irrigation, successful in several case studies.
