Abstract | TOP |
The high incidence of anomalous pancreatobiliary duct union (APBDU) in
children who have a choledochal cyst has been well documented. Additionally,
cylindrical dilatation of the bile duct has been reproduced in animal models by
anastomosing the pancreatic duct to the bile duct. In recent years, APBDU has
been considered a possible etiologic factor in the formation of a choledochal
cyst. The authors observed a progressive cylindrical dilatation of the common
bile duct in a 6-year-old boy over an 18-month period. An operative
cholangiogram showed a type Ic choledochal cyst and a type B APBDU
(Todani classification). This clinical experience suggests that a normal common
bile duct in children can be progressively dilated and become an acquired
choledochal cyst arising as a complication of the preexisting APBDU.
