摘　　要：背景:胆道并发症是肝移植术后最常见的并发症,影像学检查能直观地了解其形态学改变。目的:系统分析肝移植术后胆系并发症的影像学表现,以期评估术后疗效,并对术后并发症的防治提供依据。设计、时间及地点:于2002-01/2006-12在解放军南京军区福州总医院医学影像科完成回顾性病例分析。对象:选择资料完整的解放军南京军区福州总医院肝胆外科34例同种异体原位肝移植术后患者,男27例,女7例,所有病例均为胆总管对端吻合。方法:对34例肝移植术后患者CT,MRI及内镜逆行胰胆管造影的影像学表现进行回顾性分析,24例行螺旋CT检查,其中5例另行内镜逆行胰胆管造影检查,5例中2例同时行引流管造影;8例行MR及磁共振胰胆管造影检查。主要观察指标:肝移植术后胆总管及肝内胆管有否扩张、狭窄、胆泥形成、胆管内积气及术后继发感染、胆瘘等,原发肝肿瘤患者术后是否出现胆管转移。结果:胆总管扩张18例;所有病例均同时伴有肝内胆管扩张,左侧肝内胆管较右侧肝内胆管扩张明显,其中单纯性胆管扩张5例,13例由于胆泥致胆总管及肝内胆管扩张;胆管感染合并肝内胆管扩张积气2例,胆漏4例;肝外胆管转移性肿瘤2例。结论:双螺旋CT和MR均能显示肝移植术后胆系并发症影像,MRI及磁共振胰胆管造影、内镜逆行胰胆管造影、引流管造影均能清楚显示胆管形态及胆管胆泥,MRI较CT更能清楚显示胆泥形成。BACKGROUND： As common complications after liver transplantation, biliary complications can be directly shown by imaging. OBJECTIVE： To systematically analyze the imaging characters of biliary complications after liver transplantation, to evaluate postoperative outcome and provide reference for the prevention and treatment of postoperative complications. DESIGN, TIME AND SETTING： Retrospective analysis was performed at Department of Radiology, Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from January 2002 to December 2006. PARTICIPANTS： Thirty-four cases with biliary complications after orthotopic liver transplantation in Department of Hepatobiliary Surgery, Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA were selected, including 27 males and 7 females. All patients were bile commen duct end-to-end anastomosis. METHODS： The CT, MRI and endoscopic retrograde cholangiopancreatography （ERCP） imaging characters of 34 cases after orthotopic liver transplantation were studied retrospectively. Twenty-four cases were detected by multislice CT, of which 5 cases also checked with ERCP （2 cases undergone drainage tube opacification）; 8 cases were detected by MR and magnetic resonance cholangiopancreatography （MRCP）. MAIN OUTCOME MEASURES： Dilatation, stenosis, bilestone, intrahepatic pneumatosis, secondary infection, and biliary fistula in bile commen duct and intrahepatic bile duct; bile duct metabasis in patients. RESULTS： Eighteen cases showed choledoehus dilatation complicated by intrahepatic bile duct dilatation. The left intrahepatic bile duct dilatation was greater than the right side. Of 18 cases, 5 only showed bile duct dilation, 13 had choledoehus and intrahepatic dilatation caused by bilestone, and 2 had biliary tract infection complicated by intrahepatic bile duct dilatation and pneumatosis. In addition, 4 cases had biliary fistula, and 2 cases had metastatic tumor of extrahepadc bile duct. CONCLUSION： Double spiral CT and MR can show
