[Experience of diagnosis and treatment of congenital choledochocele]

Thirty patients with congenital choledochocele were operated upon from 1984 to 1991, including 12 cases having had previous cystoduodenostomy or cystojejunostomy. Ultrasound scans have proved to be the most effective modality in confirming the diagnosis. PTC and ERCP were extremely useful to define the types of cyst and to select operative procedure, especially in the reoperation patients. The shortcoming of cystoduodenostomy or cystojejunostomy and the details of cyst excision with Roux-en -Y hepatocholangiojejunostomy were discussed. Twenty seven patients underwent cyst excision and Roux-en-Y hepatocholangiojejunostomy. There was no operative death. Follow-up period was from 1 month to 7 years with an average of 3.7 years. Long term results were satisfactory.
