During a two years period, four children were operated on because of c
holedochal cysts. All four patients were girls aged 9, 9, 8 and 6 year
s at operation. The symptoms at presentation were mainly episodic abdo
minal pain, mild jaundice and tenderness under the right costal curvat
ure. Ultrasonography of the biliary tract revealed a cystic dilatation
of the choledochus. Endoscopic retrograde cholangiopancreatography (E
RCP) confirmed the cystic dilatation and, importantly, delineated the
junction of the pancreatic duet. The surgical procedure in all four pa
tients consisted of complete excision of the choledochal cyst and extr
ahepatic biliary tree combined with a Roux-en-Y hepaticojejunostomy. T
he postoperative course of all patients was uneventful. Ultrasonograph
y of the abdomen should be performed liberally in case of biliary trac
t symptoms in children.
