title: The changing pattern of diagnosis of infantile cholestasis.
abstract: OBJECTIVE
  Cholestatic liver disease in infancy is caused by a wide range of conditions. This study reviews the pattern of diagnosis of infants with cholestasis presenting to a tertiary referral paediatric hospital in Sydney, Australia, during a 12-year period (1985-96).
  
  
  METHODS
  Infants aged less than 6 months with cholestasis were identified retrospectively from hospital records and data retrieved from the medical records.
  
  
  RESULTS
  There were 205 infants identified as having cholestatic liver disease. The aetiology of the cholestasis was idiopathic in 25%, metabolic/genetic in 23%, and due to obstruction in 20%, parenteral nutrition in 20%, infection in 9% and bile duct hypoplasia in 3%.
  
  
  CONCLUSIONS
  This study highlights the changing patterns of diagnosis of cholestatic liver disease in infants at a tertiary paediatric facility, demonstrating that up to 50% of cases are now due to genetic/metabolic diseases or parenteral nutrition, and a high proportion are due to idiopathic disease.
