The Outcome of Patients With Cystic Biliary Atresia With Intact Proximal Hepatic Ducts Following Hepatic-Cyst-Jejunostomy.

OBJECTIVES

To determine the outcomes of patients with cystic biliary atresia by correlating the anatomy of the hepatic ducts with the choice of biliary reconstruction surgery.

BACKGROUND

The Kasai hepatoportoenterostomy (Kasai) is the initial surgical procedure offered to most patients with biliary atresia. In contrast, a hepatic-cyst-jejunostomy has been reported to be effective in patients with the cystic form of biliary atresia.

METHODS AND RESULTS

We performed an international multicenter retrospective review. Two hundred eighty-seven patients were included, and 33 cases of cystic biliary atresia were identified. Outcomes were the serum total bilirubin level 3 months post-surgery and native liver survival at 2 years of age and were compared between cases who received the Kasai versus hepatic-cyst-jejunostomy in correlation to the anatomy of proximal hepatic ducts. The patients were categorized into 3 anatomical groups: patent intact hepatic ducts (n = 10), patent hypoplastic hepatic ducts (n = 13), and obliterated hepatic ducts (n = 10). All 10 patients with patent intact hepatic duct group underwent hepatic-cyst-jejunostomy, and 9 experienced bile drainage and native liver survival. Among the 13 patients with hypoplastic hepatic ducts, 11 underwent the Kasai procedure, and 9 had bile drainage, whereas 2 underwent hepatic-cyst-jejunostomy, and one survived with the native liver. All of the patients with obliterated hepatic ducts underwent the Kasai procedure; 5 established biliary drainage and survived with the native liver. Of 5 who did not drain, 3 underwent liver transplantation.

CONCLUSIONS

In patients with cystic biliary atresia, the subset with a connection between cyst and intrahepatic bile ducts via intact proximal hepatic ducts had favorable clinical outcomes following hepatic-cyst-jejunostomy.
