Background:
Complications often follow if a choledochal cyst is treated simply by drainage, either internal or external. This study reviews 17 patients who had had previous cystoenterostomy (n = 9) or external drainage (n = 8) and who required reoperation and cyst excision.
Methods:
The study was a retrospective review including ten women and seven men managed over 9 years. The indications for reoperation were stone formation (10 patients), pancreatitis (three), portal hypertension (two) and hepatic abscess (one); two patients were asymptomatic.
Results:
Definitive surgery with cyst excision was possible in all patients who had previously had external cyst drainage and in seven of nine who had had previous cystoenterostomy. There were no deaths. Two postoperative biliary leaks and two duodenal fistulas resolved spontaneously.
Conclusion:
Excision of a choledochal cyst is possible and desirable even after a previous drainage operation. In severely ill patients with a complication of choledochal cyst, external drainage may be a preferable initial manoeuvre.
