Pre-operative evaluation of three-dimensional spiral CT cholangiography in patients with bile duct obstruction / 国际外科学杂志

ABSTRACT

ObjectiveTo study the preoperative evaluation of three-dimensional spiral CTcholangiography(SCTC) in patients with bile duct obstruction.MethodsA retrospective analysis was performed for 60patients with bile duct obstruction from May 2008 to April 2011,who were treated with endoscopic retrograde cholangiopancreatography( ERCP),then SCTC was performed through endoscopic nasobiliary drainage( EN-BD) tube,and the bile duct tree image of SCTC of bile duct obstruction was evaluated.ResultsIn 60 cases of bile duct obstruction who 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,cholecyst bile duct was visible in 80％ patients,and three-dimensional SCTC can tell the position of cholecyst duct and the place where the cholecyst bile duct enters into the common bile duct.ConclusionThree-dimensional SCTC can show the shape of bile duct tree,especially the cholecyst duct,and has some guidance values in judging the structure of the bile duct tree and the shape of cholecyst bile duct during operation.
