1、介入放射学杂志2009年7月第18卷第7期JInterventRadiol2009,Vol.18,No.7—543—·临床研究Clinicalresearch·PTC对胰胆管合流异常的鉴别诊断赵明,李臻,韩新巍,张川,张蓓【摘要】目的探讨经皮肝穿刺胆道造影(PTC)诊断胰胆管合流异常(PBM)的可行性、影像学表现及其与Oddi括约肌功能异常(SOD)的影像学鉴别诊断。方法回顾性分析363例阻塞性黄疸患者行PTCD治疗的临床及影像学资料,确立病例入选标准、PBM诊断参考标准。由2名高年资医师阅片,分析临床
2、资料完整的胰管显影病例,影像学测量其胆胰共同管长度,并经校正得到实际数值,与正常值进行统计学比较。对非PBM型胰管显影者分析,结合临床及现行的SOD临床诊断标准,作出初步诊断。结果42例胰管显影的病例中,临床初诊PBM38例,SOD4例。PTC显示38例PBM患者胆总管、胰管在十二指肠壁外高位汇合,共同管较长,为(12.6±7.9)mm,明显高于正常长度标准6mm(t=5.15,P<0.05);且十二指肠乳头开口越远,共同管越长。4例SOD中,1例为胆囊切除术后综合征,3例考虑为胰胆管间纵行括约肌缺如。
3、结论PTC是诊断PBM的可行方法之一,结合临床可初步与SOD影像诊断相鉴别。但诊断PBM首选无创性诊查方法。【关键词】胰胆管合流异常;影像诊断;经皮肝穿刺胆管造影术;Oddi括约肌功能异常中图分类号:R576文献标志码:A文章编号:1008-794X(2009)-07-0543-04TheclinicalvalueofPTCfindingsinthedifferentiationofpancreaticobiliarymaljunctionsZHAOMing,LIZhen,HANXin-wei,ZHAN
