摘　　要：目的 探讨多层CT在肝移植术后胆道并发症中的诊断价值.方法 44例肝移植术后胆道并发症病人接受多层CT动态增强扫描,并于1周内行胆道造影检查（cholangiography,CP）.以CP结果为对照,分析多层CT诊断肝移植术后胆道并发症的能力.CT对胆道系统的评价以动态增强门静脉晚期图像为基础,并结合胆道系统多平面重建进行分析.结果 CP证实肝外胆管（胆总管和肝总管）狭窄23例,左、右肝管狭窄24例,肝内胆管狭窄27例.CT诊断肝外胆管狭窄的敏感度、特异度、正确率、阳性预测值、阴性预测值分别为91.3%、83.3%、87.8%、87.5%、88.2%;诊断左、右肝管狭窄的敏感度、特异度、正确率、阳性预测值、阴性预测值分别为83.3%、88.2%、85.4%、90.9%、78.9%;诊断肝内胆管狭窄的敏感度、特异度、正确率、阳性预测值、阴性预测值分别为74.1%、92.7%、80.5%、95.2%、65.0%.CT发现4例肝内胆汁瘤及2例肝脓肿,而CP仅发现其中2例胆汁瘤,另4例因严重胆管狭窄和胆泥阻塞在CP上未能显影.CP证实3例吻合口胆漏,CT仅显示肝门区和腹腔积液,对漏口位置不能显示.CP证实33例肝内外胆管结石或胆泥,CT诊断的敏感度、特异度、正确率、阳性预测值、阴性预测值分别为72.7%、100.0%、78.1%、100.0%、47.6%.此外,CT检查正确诊断1例弥漫性肝内胆管狭窄病人的急性活动性胆道出血.结论 多层CT可作为诊断肝移植术后胆道并发症的常用检查方法,对诊断胆管狭窄、胆漏、胆管结石或胆泥以及肝实质病变、急性胆道出血具有重要价值.Objective To analyze the role of multislice spiral CT in the diagnosis of biliary com-plications following liver transplantation. Methods Forty-four patients with biliary complications re-ceived tri-phase contrast-enhancement CT examination and cholangiography （CP） within one week af-ter the CT scanning. Using the results of CP as the standard, we investigated the efficacy of multislice spiral CT for each kind of biliary complication. All the analyses for bile duct were based on the images on the late portal venous phase and the reconstruction of images performed with multiplan reformat,Results CP depicted biliary strictures involved in extrahepatic bile duct in 23 cases （including the common bile duct and common hepatic duct）, left or right hepatic duct in 24 and intrahepatic bile duct in 27. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of the CT examination were 91.3%, 83. 3% , 87. 8%, 87. 5% and 88. 2% for biliary stricture in extrahe-patic bile duct, 83. 3% , 88. 2%, 85. 4%, 90. 9% and 78. 9% for biliary stricture in left or right he-patic duct, 74.1%, 92.7%, 80.5%, 95.2% and 65.0%, for biliary stricture in intrahepatic bile duct, respectively. CT detected intrahepatic biloma in 4 cases and abscess in 2 but CP only detected biloma in 2 cases. The other 4 cases did not detected by CP because of severe biliary strictures which filled with biliary sludge. CP confirmed anastomotic bile leak in 3 cases. In these cases, CT only de-picted the fluid collection in hepatic hilum and abdominal cavity, none of the exact leak site could be detected. CP detected biliary sludge or stones in 33 cases. However, the sensitivity, specificity, accu-racy, positive predictive value and negative predictive value of the CT examination for biliary sludge or stones were 72.7%,100.0%,78.1%,100.0%and 47.6%,respectively.Meanwhile,in 1 patient with diffuse intrahepatic biliary strictures,active biliary bleeding was correctly detected by CT exami-nation and confirmed by hepatic ar
