【摘要】：目的:比较CT与超声检查诊断各种病理类型阑尾炎的临床应用价值。方法:收集临床拟诊为阑尾炎患者162例,均行CT平扫和超声检查并进行阑尾炎临床分型,对照术后病理结果,计算诊断准确率、特异度、灵敏度、阴性预测值、阳性预测值,比较两种检查诊断阑尾炎差异有无统计学意义。结果:经手术后病理证实阑尾炎156例,CT和超声检查诊断准确率分别为91.3%、82.1%,特异度分别为50.0%、66.7%,灵敏度分别为94.9%、85.3%,阴性预测值分别为27.3%、14.8%,阳性预测值分别为98.0%、98.5%。CT与超声检查诊断阑尾炎的准确率差异具有统计学意义。结论:CT和超声检查对阑尾炎的病程进展及不同病理类型的诊断具有重要的临床应用价值,CT诊断单纯性及慢性阑尾炎优于超声检查,可作为超声结果阴性的补充检查方法,为临床提供重要参考信息。
[Abstract]:Objective: to compare the clinical value of CT and ultrasonography in the diagnosis of various pathological types of appendicitis. Methods: 162 patients with appendicitis were examined by plain CT scan and ultrasound, and the clinical classification of appendicitis was performed. The accuracy, specificity, sensitivity, negative predictive value and positive predictive value of appendicitis were calculated. The difference between the two examinations in the diagnosis of appendicitis was statistically significant. Results: the diagnostic accuracy of CT and ultrasound in 156 cases of appendicitis proved by operation and pathology was 91.3 and 82.1, the specificity was 50.066.7, the sensitivity was 94.9 and 85.3, the negative predictive value was 27.30.58, and the positive predictive value was 98.098.5.CT and ultrasound were respectively used to diagnose the appendicitis. The accuracy of appendicitis is statistically different. Conclusion CT and ultrasound have important clinical application value in the diagnosis of appendicitis and different pathological types. Ct is superior to ultrasound in the diagnosis of simple and chronic appendicitis, and can be used as a supplementary examination method for negative results of ultrasonography. To provide important reference information for clinical practice.
