title: Biliary ascariasis--a worm in the duct.
abstract: OBJECTIVE
  Migration of Ascaris lumbricoides into the biliary tree may cause biliary obstruction, cholangitis or pancreatitis. Although common in endemic areas, none of these complications have previously been reported in Australia. We report here a case of obstruction of the common bile duct by an ascarid.
  
  
  METHODS
  A 62-year-old female Vietnamese migrant presented with cholangitis and underwent a cholecystectomy. Subsequently, ultrasound and cholangiography revealed an ascarid in the common bile duct.
  
  
  RESULTS
  This worm was endoscopically removed and the patient's symptoms rapidly resolved.
  
  
  CONCLUSIONS
  As a result of increased migration to Australia, such cases will be recognised more frequently in the future. Patients at risk should be carefully imaged prior to definitive therapy.
