肝移植术后的磁共振胰胆管水成像(MRCP)评估

MRI EVALUATION OF BEFORE LIVER TRANSPLANTATION

目的:探讨MRCP在原位肝移植术后早期诊断胆道狭窄的价值。方法:收集已行原位肝移植手术的病人43例,术后胆总管吻合口有不同程度狭窄的病人均行MRCP复查,比较有临床症状及无临床症状病人的MRCP的差别,并做统计学分析。结果:MRCP能客观评价胆总管吻合口狭窄程度,狭窄指数大于0.67与小于0.33及介于二者之间的出现临床症状的机率不同,有统计学意义(P<0.05)。结论:随着MRI技术的不断发展,MRCP作为一种非侵袭性影像检查方法,能快速诊断肝移植术后出现的胆道狭窄,对指导临床诊断及治疗具有重要意义。

Objective：To evaluate the application of MRCP in value of diagnosing confined bile duct early after liver transplantation. Methods：43 cases who had underwent orthotopic liver transplantation have been collected. After orthotopic liver transplantation 43 patients whose bile ducts had anastomotic strictures underwent MRCP to compare the imaging of MRCP between the patients who had the clinical symptom and who had not. Then we analysed statistically and found other complications after liver transplantation by MRI. Results：MRCP can impersonally evaluate the extent of stricture in bile ducts. It has less probability in the group whose confined extent exceed 0. 67 than whose less than 0. 33,that has significant difference（P〈0. 05）. Conclusion：With the technology of MRI developing continually,MRCP as an imaging method of non-breaking into,can diagnoses bile duct syndromes after liver transplantation fleetly. And it is important for direction for clinical diagnoses and cure.
