Late surgical complications of choledochal cystoenterostomy

Choledochal cyst is a rare congenital abnormality of the biliary tract characterized by dilatation and stasis. Cyst excision is now preferred to internal drainage because of the predilection for development of cancer in the unresected cyst wall. We report on four patients who required reoperations for complications of prior cystenteric drainage from 14 to 21 years after the original operations. Gastrointestinal bleeding from cyst ulceration as occurred in one patient is heretofore unreported
