梗阻性黄疸的多层螺旋CT诊断价值

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。

Diagnostic accuracy of MSCT on obstructive jaundice

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.
