ABSTRACT

Objective To evaluate of three-dimensional spiral CT cholangiography to bile duct configuration before laparoscopic cholecystectomy.Methods A retrospective analysis was performed for 60 patients with cholelithiasts concurrent with choledocholithiasis from May 2009 to April 2012,which were treated with endoscopic retrograde cholangiopancreatography (ERCP),endoscopic sphincterotomy (EST),and endoscopic nasobiliary drainage (ENBD),then three-dimensional spiral CT cholangiography(SCTC) was performed through endoscopic nasobiliary drainage (ENBD) tube,and the bile duct tree image of SCTC was evaluated,then laparoscopic cholecystectomy (LC) was carried out.Results Sixty cases were performed three-dimensional SCTC.The left and right hepatic bile ducts,the hepatic bile duct and the common bile duct were visible in 100％ patients,and cholecyst bile duct was visible in 75％patients,and three-dimensional SCTC can tell the position of cholecyst duct and the place where the cholecyst bile duct enteres into the common bile duct.Conclusion Three-dimensional SCTC can show the shape of bile duct tree,especially the cholecyst duct,and has some guidance values to judge the structure of the bile duct tree and the configuration of cholecyst bile duct during operation,which can decrease the possibility of bile duct injure.
