梗阻性黄疸的多层螺旋CT诊断价值

Diagnostic accuracy of MSCT on obstructive jaundice

目的探讨多层螺旋CT对梗阻性黄疸梗阻部位和病因的诊断价值。方法对86例梗阻性黄疸患者的临床资料进行回顾性分析,对比多层螺旋CT检查结果与术中所见和病理检查结果的一致性。结果 86例患者中,术中所见及术后病理证实梗阻部位在肝外胆管者9例,梗阻部位在肝内胆管者57例,梗阻部位在胰头部14例,梗阻部位在十二指肠乳头部者6例。而CT检出结果分别为7例、46例、14例和3例,总准确率86%。梗阻病因中,胆管结石56例,胆管炎性疾病10例,胆管肿瘤4例,乳头部肿瘤5例,胰头癌11例。经CT检出结果分别为48例、6例、2例、4例和11例,总准确率80%。结论多层螺旋CT作为临床常规诊断手段,具备多层面扫描、无需使用造影剂、检查准确率高等优点,而且方便基层医院使用,有利于临床的广泛应用,值得临床广泛推广。

Objective To investigate the diagnostic accuracy of multislice spiral computed tomography （MSCT） on the location and etiology of obstructive jaundice. Methods Analyze 86 cases′clinical data by retrospective anal-ysis method, and compare the CT scan results with the intraoperative findings and pathology results. Results Eighty-six patients′data was analyzed, the location of obstructive jaundice were in extrahepatic bile duct , intrahepatic bile duct, pancreatic and duodenal papilla, the total accuracy of CT scan is 86.0%. The etiology of obstructive jaundice were bile duct stones, cholangitis, bile duct cancer, duodenal tumors and pancreatic cancer, the the total accuracy of CT scan is 80%. Conclusion Multislice spiral computed tomography （ MSCT） has high accuracy on the location and etiology for obstructive jaundice.
