Management of adult choledochal cysts - A 15-year experience

Abstract

Background. Choledochal cyst, a common surgical problem of childhood, can have a delayed presentation in adults. The clinical course in adults differs from that in children because of a higher incidence of associated hepatobiliary pathology. Methods. The clinical data of 57 adults with choledochal cyst managed in a general surgical unit between January 1988 and March 2003 were analysed. Results. The male:female ratio was 1:1.38 and the mean age was 34.5 years; 71.9% of the cysts belonged to Todani type I, 26.3% to type IV and 1.8% to type V. Abdominal pain and recurrent cholangitis were the commonest presentations followed by acute pancreatitis, palpable mass and bronchobiliary fistula. Anomalous pancreaticobiliary ductal junction was demonstrated in 14% of the cases. In all, 37% of the patients had undergone either wrong or suboptimal surgical procedures prior to presentation. All patients underwent complete excision of the cyst and hepaticojejunostomy. Two patients required cholangiojejunostomy and three patients required resection of the involved segments of the liver in addition. There were three anastomotic leaks and two postoperative deaths. Two anastomotic leaks resolved spontaneously while the third required surgical intervention. Forty-eight patients were available for follow-up and have remained symptom-free over a mean period of 17.6 months. Conclusions. Choledochal cyst should be considered in all patients below 40 years of age presenting with biliary colic, pancreatitis or recurrent cholangitis with associated dilatation of bile duct. Complete excision of the cyst with restoration of biliary-enteric communication by hepaticojejunostomy form the basis of ideal treatment. © 2006 Taylor & Francis.
