Recent experience with choledochal cyst.

This report details an 11-year experience with 17 patients ranging from newborn to 17 years with choledochal cyst. Two distinct groups were noted: an infantile group (mean age: 3 months) with obstructive jaundice identical to biliary atresia and a late onset group (mean age: 9 years) with various combinations of pain, mass, and jaundice. Two patients had cystoduodenostomy performed and both required revision. One of six patients who had Roux-Y cystojejunostomy required revision. All seven patients who had primary cyst excision and two patients who had secondary cyst excision with Roux-Y hepaticojejunostomy have been followed prospectively and have done well. The follow-up period ranges from 1-11 years with an average of 5.8 years. Cyst excision should be performed as a primary or secondary procedure whenever feasible. The rare patients with intrahepatic ductal dilatation (Caroli's disease) are best approached by hepatic lobectomy when possible, and those with choledochocele should be treated by unroofing the cyst as indicated by the anatomy encountered.
