CHOLEDOCHAL CYSTS IN CHILDREN

Choledochal cysts (CC) are congenital dilation of the common bile duct (BC) which can lead to progressive biliary obstruction and biliary cirrhosis. Analysis of the literature shows that there is no terminological unity between different authors. In the literature this pathology is described under different names: cystic transformation of external bile ducts cystic transformation of duodenum congenital dilation of duodenum CC choledochocele duodenal diverticulum megacholedochus hepaticholedochus cyst idiopathic choledochus dilation etc. [9 41]. In spite of different terms we are talking about different forms and manifestations of the same pathology. At the same time in most cases dilation is not limited to extrahepatic bile ducts but extends to intrahepatic bile ducts that gives the grounds to consider cystic dilation as a disease of all biliary tract.
