Surgical treatment for infant biliary hypoplasia with huge choledochal cyst / 中华普通外科杂志

ABSTRACT

Objective To explore diagnosis and treatment of biliary hypoplasia with huge choledochal cyst in infants.Methods From Feb 2003 to Dec 2011,278 choledochal cyst cases were treated in our hospital.There were 3 infant cases of biliary hypoplasia with huge extrahepatic choledochal cyst diagnosed and treated during this period.All patients underwent cholangiogram demonstrating patent,but markedly diminutive extrahepatic biliary structures.After excision of the cyst,hepatic duct was injured in 1 case.The cyst wall was removed,a stent was put inside of hepatic duct,and Roux-en-Y hepaticojejunostomy was porformed.Results All three patients (ages from 1 month to two months) received the Roux-en-Y hepaticojejunostomy,none of our patients has developed stenosis and fistula of the Roux-en-Y hepaticojejunostomy.Intraoperative cholangiogram showed the huge choledochal cyst and diminutive intrahepatic ducts.All three cases were followed-up for 1-5 years,there was no jaundice and nor stones formation.Conclusions In cases of huge choledochal cyst when intraoperative cholangiogram demonstrates a diminutive biliary tree with huge choledochal cyst,great care is required during cyst excision in order not to injury the hepatic duct.Stent placement into hepatic duct helps bile flow at early stage after surgery.
