二维超声对肝移植术后胆道并发症的诊断价值

目的:探讨二维超声对肝移植术后胆道并发症的诊断价值.方法:回顾性分析48例肝移植术后胆道并发症患者的二维超声图像,并与其它影像学检查结果相对比.结果:超声检出胆漏13例,胆管扩张36例,胆汁淤积16例,胆泥形成10例,结石形成13例.术后1个月内发生者37.8%,3个月内发生者68.9%.7例患者出现极其相似的病程,表现为胆管扩张,后扩张胆管内出现胆汁淤积,继而胆泥形成,最后发展至胆管结石.结论:超声在肝移植术后胆道并发症的诊断中有重要应用价值,是首选检查方法.

Value of B-mode Ultrasonography in the Diagnosis of Biliary Complications after Liver Transplantation

Objective:To investigate the value of B-mode ultrasonography in the diagnosis of biliary complications after liver transplantation.Methods:The ultrasonograms of 48 patients complicated with biliary tract disorders after liver transplantation were retrospectively studied.The diagnostic results of ultrasonography were respectively compared with those of the ERCP or MRCP or biliary tract contrast examination through T tube. Results:B-mode ultrasonographic examinations detected biliary tract leaks in 13 cases,dilatation of the biliary ducts in 36 cases,cholestasis in 16 cases,bile sludge formation in 10 cases and cholelithiasis in 13 cases.In 37.8% of the cases,the complications occurred within a month post-operatively,while in 68.9% of the cases,the complications were shown within three months after liver transplantation.The pathological process and evolution of biliary complications in 7 cases simulated very much.Initially,dilatation of the biliary ducts and subsequent cholestasis were seen,then,bile sludge formation occurred and finally cholelithiasis developed.Conclusion:Clinically,B-mode ultrasonography played an important role and might be recommended as the first choice imaging modality in the detection and diagnosis of post-operative liver transplantation biliary complications.
