移植肝胆管并发症的超声、CT、MRI诊断比较

Biliary Complication of Orthotopic Transplant Liver: Comparative Study of Ultrasound, CT and MRI

目的:探讨移植肝胆管并发症超声、CT、MRI诊断效果。方法:回顾分析98例移植肝患者超声、CT、MRI资料。结果;全部患者均行超声检查,超声诊断胆管扩张25例,胆管壁回声增强7例,胆漏5例,胆管结石3例,胆泥5例。15例行MRI检查,MRI诊断胆管扩张9例,胆泥1例,肝内胆漏1例。39例行CT检查,CT诊断胆管扩张15例,胆漏4例,结石2例。超声与CT、MRI相比,诊断结果无显著差别。结论:超声、CT、MRI诊断移植肝胆管并发症效果相当,超声适合肝移植术后定期随访,CT、MRI对肝外胆臂病变诊断优于超声,介入超声有助于胆漏的鉴别诊断及治疗。

Objective： To investigate the diagnostic effect of ultrasound, CT and MRI in the biliary complication of orthotopic transplant liver. Methods： Ninety-eight cases of orthotopic liver transplantion were retrospectively analysed. Results： Ultrasound were performed in all patients and detected twenty-five biliary dilatations, five bile leaks, three biliary stones, five biliary sludges. MRI were performed in fifteen patients and found nine biliary dilatations, one bile leak, one biliary sludge. CT were performed in thirty-nine patients and detected fifteen biliary dilatations, four bile leaks, two biliary stones. There were no significant differences in diagnostic results between ultrasound and CT or ultrasound and MRI. Conclusion：Ultrasound, CT and MRI are similar in diagnosis of biliary complications of transplant liver. Ultrasound is suitable for periodical examination. CT, MRI are better than ultrasound in extrahepatic duct complications diagnosis. Interventional ultrasound is useful in diagnosis and treatment of bile leaks.
