Objective To determine the clinical value of MRCP for peroperative evaluation of donor biliary system in living donor liver transplantation (LDLT). Methods A total of 60 living donors for the LDLT were enrolled in this study. Of the 60 donors with a mean age of 32.2 (19-60), 50were male and 10 female. MRCP was performed before and cholangiography was done during the right lobectomy in these donors. The results of MRCP were compared with those of cholangiography to determine the value of MRCP for typing the biliary system in the donors. Results The preoperative MRCP showed that 40 donors were of type Ⅰ biliary tract, 12 of type Ⅱ , 5 of type Ⅲ and 3 of other types. The intraoperative cholangiography showed that the accordance rate of MRCP was 97.4%,91% and 89% for type Ⅰ , type Ⅱ and other types, respectively. The overall rate of accuracy of MRCP was 95% (57/60). Conlusion MRCP can show types of biliary tract in living donors for liver transplantation to provide evidence for plan of surgery.%目的 评价应用MRCP术前评估活体肝移植供者胆管系统的临床意义.方法 60例活体肝移植供者(男50例,女10例,年龄19～60岁,平均32.3岁),于右半肝切取术前行MRCP检查,术中经胆囊管行胆道造影.回顾性分析这些活体肝移植供者术前MRCP和术中胆道造影结果,二者进行比较,对比术中胆道造影结果评价MRCP在活体肝移植供者胆管分型方面的准确性.结果 根据术前MRCP结果,所有60例活体肝移植供者均可以判断出肝内胆管分型情况,1型胆管40例,2型胆管12例,3型胆管5例,其他3例.术中胆道造影显示1型胆管39例,MRCP正确诊断38例,准确率为97.4%;术中胆道造影显示2型胆管12例,MRCP正确诊断出11例,准确率为91%;术中胆道造影显示其他胆管类型为9例,MRCP正确诊断出8例,准确率为89%;MPCP总体准确率为95%(57/60).结论 MRCP可以在术前较为准确地显示活体肝移植供者胆管分型,为临床制定手术方案提供依据.
