【摘要】 目的探讨磁共振胰胆管成像(MRCP)对胆道术后并发症的诊断价值及局限性。方法采用快速自旋回波水成像技术对58例胆道术后(胆囊切除术41例,胆总管探查术6例,肝管空肠吻合术11例)出现不明原因发热、黄疸、右上腹痛等症状患者进行MRCP检查,并与直接胆管造影、B超或手术结果对照分析,着重观察是否存在残余胆囊、胆管狭窄、胆道结石、吻合口狭窄等术后并发症。结果MRCP可以满意显示术后胆道全貌,对残余胆囊、胆管狭窄、胆道结石、胆管扩张、吻合口狭窄诊断的准确率分别为77.8%、71.4%、87.5%、100%、88.9%,对胆管狭窄、胆肠吻合口定位准确率均为100%。结论MRCP对胆道术后并发症的诊断和鉴别诊断有重要价值,为临床进一步治疗提供可靠依据。更多还原

【Abstract】 Objctve To probe the diagnostic value and limitation of MRCP for postoperative complications of biliary tract. Methods MRCP using fast - spin - echo hydrography was performed in 58 patients who had unexplained fever, right up per quadrant pain and jaundice after the surgery of biliary tract. The results were compared with the direct cholangiographic, ul trasound B and surgical findings, focusing on whether the postsurgical complication, such as residual gallbladder, stenosis of bili ary tract, biliary calculi and anastomostic stenosis. Results MRCP can show the postsurgical biliary tract perfectly. The accura cy for residual gallbladder, ductal stenosis, intraductal stone ,ductal dilatation, anastomostic stenosis were77.8% ,71.4% ,87. 5% . 100% ,88. 9% ,moreover, The accuracy rate of MRCP for localizing stenosis of biliary tract and the choledochenteric anasto mosis all were 100%. Conclusion MRCP play an important role in the diagnosis and differential diagnosis of the plstoperative complication of biliary tract, thus offers a reliable foundation for clinical treatment.更多还原
