目的探讨细菌移位检测联合螺旋CT小剂量扫描诊断急性阑尾炎的临床价值。方法收集2013年10月-2015年1月就诊的疑似急性阑尾炎患者200例,并对所有患者进行细菌移位检测及螺旋CT小剂量扫描,根据诊断标准,比较单独使用螺旋CT小剂量扫描诊断与联合诊断的诊断结果。结果 200例疑似急性阑尾炎患者最终确诊168例,排除32例。细菌移位检测联合螺旋CT小剂量扫描诊断灵敏度、阴性率、阴性似然比和诊断正确率明显高于单独使用螺旋CT小剂量扫描诊断,差异均有统计学意义(P<0.05)。联合诊断阳性率、特异度及阳性似然比虽高于单独使用螺旋CT小剂量扫描诊断,但差异均无统计学意义(P>0.05)。结论细菌移位检测和螺旋CT小剂量扫描联合应用可提高急性阑尾炎诊断的准确率。
Objective To investigate the clinical value of bacterial translocation detection combined with low-dose spiral CT in the diagnosis of acute appendicitis. Methods 200 cases of suspected acute appendicitis from October 2013 to January 2015 were enrolled in this study. Bacterial translocation detection and low-dose spiral CT scanning were performed on all patients. According to the diagnostic criteria, low dose CT scan alone Diagnostic test results. Results A total of 200 cases of suspected acute appendicitis were finally diagnosed in 168 cases, excluding 32 cases. The diagnostic sensitivity, negative rate, negative likelihood ratio and diagnostic accuracy of low-dose spiral CT were significantly higher than those of low-dose spiral CT alone (P <0.05). Although the positive rate, specificity and positive likelihood ratio of combined diagnosis were higher than those of low-dose spiral CT alone, the difference was not statistically significant (P> 0.05). Conclusions The combination of bacterial translocation detection and low-dose spiral CT can improve the diagnostic accuracy of acute appendicitis.
