[Choledochal cyst. Presentation of 5 cases in childhood].

Five cases of choledochal cyst diagnosed from 1976 to 1983 are presented. Four patients began in the neonatal period as a cholestatic syndrome resembling biliary atresia and one patient began later on as a cholangitis. It is important for diagnosis the use of ultrasounds and radionuclide hepatobiliary. Clinical course depends on early diagnosis and treatment, because there is often an atresia of the common hepatic duct associated.
