目的 探讨 ERCP后 CT扫描的临床价值。材料与方法 34例阻塞性黄疸患者进一步作 ERCP后 CT扫描。方法为ERCP拔管后 1～ 2小时行 CT扫描。对比评价 ERCP后 CT扫描与单纯 ERCP检查有无不同。结果 34例患者两种检查方法正确诊断 19例 ,ERCP误诊或诊断不全面 ,由 ERCP后 CT扫描诊断正确 13例 ,ERCP后 CT扫描误诊或诊断不全面 ,由 ERCP作出正确诊断 1例 ,两种方法共同误诊 1例。经配对 χ2检验 ,P<0 .0 5。结论 ERCP后 CT扫描将 ERCP和 CT二者结合起来 ,可取长补短 ,提高诊断正确率 ,具有较高的临床价值
Objective To investigate the clinical value of post-ERCP CT scan. Materials and Methods 34 patients with obstructive jaundice were further scanned by ERCP. Method for ERCP extubation 1 to 2 hours after CT scan. Comparison of post-ERCP CT scan with simple ERCP check whether there is any difference. Results Of the 34 cases, 19 cases were correctly diagnosed by both methods. ERCP was misdiagnosed or incompletely diagnosed. Thirteen cases were correctly diagnosed by post-ERCP CT scan, misdiagnosed or incomplete CT scan by ERCP, and one case diagnosed correctly by ERCP Methods Common misdiagnosis in 1 case. Paired χ2 test, P <0. Conclusions Post-ERCP CT scan combines ERCP with CT, which can complement each other and improve diagnosis accuracy, which has high clinical value
