二维超声和CT诊断阻塞性黄疸与术后病因病理诊断符合率的比较

Comparison the preoperative diagnosis accuracy rate of two-dimensional ultrasound and CT with postoperative etiology and pathology in the diagnosis of obstructive jaundice

目的比较二维超声和CT术前诊断阻塞性黄疸与术后病因病理诊断符合率,以判定二维超声与CT对阻塞性黄疸的诊断价值。方法选择经手术治疗的阻塞性黄疸患者190例,按术前检查方法的不同分为超声组112例(术前行二维超声检查)和CT组78例(术前行CT检查),回顾性分析两组的诊断并与手术后病因病理诊断比较。结果超声组、CT组对结石诊断准确率(98.0%&97.2%)、对恶性肿瘤诊断的准确率(93.5%&93.9%)、与术后病因病理诊断符合率(85.7%&87.2%),经检验差异均无统计学意义(P>0.05),同时也观察到二维超声与CT对良性病变诊断符合率(72.2%&72.7%)均较低。结论二维超声对结石及大多数恶性肿瘤所致的阻塞性黄疸具有与CT同样重要的诊断价值,且费用低廉,应列为首选。

Objective To compare the preoperative diagnosis accuracy rate of two-dimensional ultrasound and CT with postoperative etiology and pathology in the diagnosis of obstructive jaundice,to determine the value of two-dimensional ultrasound and CT diagnosis of obstructive jaundice.Methods To Select 190 cases of patients with obstructive jaundice treated by surgery,they were divided into the ultrasound group of 112 patients（two-dimensional ultrasound examination before surgery） and the CT group of 78 patients （CT examination before surgery）according to different methods of preoperative examination.To retrospective analysis the diagnostic of two groups and compare with etiological pathological diagnosisof post-operative.Results The diagnostic accuracy of the ultrasound group and the CT group （98.0% 97.2%）,the diagnostic accuracy of malignant tumors（93.5% 93.9%）,the pathological diagnosis rate of post-operative （85.7% 87.2%）,there was no significant difference by test（P0.05）.Conclusion Two-dimensional ultrasound diagnosis was equally important value with CT on obstructive jaundice caused by stones and the majority of malignant tumors,and low cost,be the best choice.
