Choledochal cysts--report of three cases and review

Three cases of choledochal cyst are presented, with a review of previous publications. We re-emphasize the diagnostic dilemma involved and discuss current surgical management. A new complication is illustrated and an association with polycystic kidneys is reported. Choledochal cysts are uncommon, but correct management ensures a symptom-free future for the patient. Recent reports support cyst excision if technically feasible.
