CT和B超对急性阑尾炎诊断和鉴别中的应用价值对照研究

The application value of CT and B ultrasound in the diagnosis and differential diagnosis of acute appendicitis

目的:对比CT和B超在急性阑尾炎诊断和鉴别诊断中的应用价值。方法:随机选择以急性阑尾炎作为诊断进行治疗并行手术的患者100例,分别给予B超及CT检查,以术后病理作为最终的诊断结果,观察B超、CT对急性阑尾炎诊断的灵敏度和特异度。结果:100例患者最终病理确诊94例,B超检查的灵敏度为88.30%,特异度为50.00%。CT检测的灵敏度为95.5%,特异度为83.33%。B超检查的灵敏度与特异度均低于CT检测,差异具有统计学意义(P<0.05)。结论:B超检查对急性阑尾炎方便快捷,价格便宜,但是其诊断的灵敏度和特异度均低于CT检查,因此对于B超检查排除的疑似病例应予以CT检查以减少漏诊和误诊。

Objective To compare the application value of CT and B ultrasound in the diagnosis and differential diagnosis of acute appendicitis. Method 100 cases with acute appendicitis were selected as the research object. All patients were given B ultrasound and CT examination, and the final diagnosis results were observed after operation. The sensitivity and specificity of the diagnosis of acute appendicitis were observed by the observation of B ultrasound and CT. Results 100 cases of 94 patients pathologically diagnosed. The sensitivity and the specificity of B uhrasonography was 88. 30% and 50. 00%, respectively. The sensitivity and the specificity of CT was 95.5% and 83. 33% ,respectively. The sensitivity and the specificity of B ultrasonography lower than the CT detection,the difference was statistically significant （P 〈 0. 05）. Conclusion B ultrasonography in acute appendicitis convenient, cheap,but the diagnostic sensitivity and specificity were lower than CT, so for B ultrasound examination to exclude suspected cases should be CT examinations to reduce the misdiagnosis and missed diagnosis.
