摘　　要：目的探讨螺旋CT三维胆道成像对胆道梗阻患者的术前评估。方法回顾性分析2008年5月-2011年4月胆道梗阻患者60例，先行内镜下逆行胰胆管造影及内镜下鼻胆引流术，通过鼻胆引流管行螺旋CT三维胆道成像，评价螺旋CT三维胆道成像对胆道梗阻患者的胆道树成像的图像质量。结果螺旋CT三维胆道成像60例，胆总管、肝总管、左右肝管显影60例，显影率为100％，胆囊管显影48例，显影率为80％，可清晰显示胆囊管的走行及汇入胆总管的位置。结论螺旋CT三维胆道成像可清晰显示胆道树结构，尤其是胆囊管的走行，为术中判断胆道树结构及胆囊管走行有一定的指导意义。Objective To study the preoperative evaluation of three-dimensional spiral CTcholangiogra- pby（SCTC） in patients with bile duct obstruction. Methods A retrospective analysis was performed for 60 patients 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. Results In 60 ca- ses 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. Conclusion Three-dimensional SCTC can show the shape of bile duct tree, especially the eholecyst duct, and has some guidance values in judging the structure of the bile duct tree and the shape of eholecyst bile duct during operation.
