Choledochal cyst.

From the review of the literature it would seem that excision as the most appropriate method of treatment is generally preferred to the internal drainage procedures. Despite the strong arguments in favor of primary excision, approximately two-thirds of patients undergoing Rouxen-Y choledochocystojejunostomy experience excellent results in both the short and long term follow-up periods. There is much to be said for recommending the Roux-en-Y choledochocystojejunostomy as the primary method of treatment of choledochal cysts, especially when the procedure is undertaken by inexperienced surgeons, and to reserve excision for those patients who have complications.
