Hepaticoduodenostomy at the hepatic hilum after excision of choledochal cyst

Abstract

During the past 11 years, 30 patients, aged 27 days to 25 years, underwent excision of choledochal cyst. Reconstruction of the biliary tract was performed by two techniques: hepaticoduodenostomy in 19 patients and Roux-Y hepaticojejunostomy in 11. The technique of hepaticoduodenostomy consisted of transection of the common hepatic duct at the hilum with an incision extending approximately 5 mm along the lateral wall of both the hepatic ducts to permit a wide anastomotic stoma. There was no mortality. Postoperative cholangitis occurred in five patients, four of whom were in the hepaticoduodenostomy group. All episodes except one responded to antibiotics and have resulted in no demonstrable hepatic dysfunction. Intestinal bleeding occurred in one Roux-Y patient and postoperative intestinal obstruction in another. There was no significant difference in the results of these two procedures in the follow-up period (average length 4 years, 3 months). The hepaticoduodenostomy with a wide stoma at the hilum is advocated because (1) it has significant capability of preventing cholangitis, which has been thought to be the primary objection so far, (2) it creates a better physiologic state, and (3) it may be associated with fewer postoperative complications.
