[Operative procedures for choledochal cyst].

Fifty one operations for choledochal cyst were carried out upon 46 patients: 41 as a primary operation and 10 as reoperation. An excision of choledochal cyst with hepaticojejunostomy in Roux-en-Y fashion at the second laparotomy gave a favorable results in all patients who suffered recurrent symptoms after the previous anastomotic procedure. Comparing operation time, blood loss and operative results of the reoperations with those of the primary, it was concluded that all choledochal cyst should be excised at the first operation unless other reason avoiding excision exists. Hepatic portojejunostomy is recommended for choledochal cyst with an associated distal atresia and the hypoplastic hepatic duct.
