摘要
目的:比较CT和改良Alvarado评分对急性阑尾炎的诊断价值,探讨年龄和性别因素对诊断的影响。方法:回顾性分析127例经CT检查并有改良Alvarado评分记录的可疑急性阑尾炎患者资料,用受试者工作特征曲线(ROC)比较两种检查方法的诊断价值。结果:从所有患者总体考虑CT检查ROC曲线下面积大于改良Alvarado评分,敏感度相对较低,但特异度相对较高。患者年龄和性别因素对CT诊断的影响很小,对改良Alvarado评分影响较大(老年妇女曲线下面积最小)。结论:CT对急性阑尾炎的诊断价值高于改良Alvarado评分,对可疑急性阑尾炎需结合CT检查,尤其老年女性患者。
Objective:To compare the value of CT and modified Alvarado score and to study the influence of patients' age and sex in the diagnosis of acute appendicitis. Methods: CT arld the record of modified Alvarado score were retrospectively analyzed in 127 cases with suspected acute appendicitis. Receiver operating characteristic (ROC) curve was used to compare the diagnostic performance of these two methods. Results: The overall area under ROC curves for CT was larger than that of modified Alvarado score. Compared with modified Alvarado score, CT showed relatively lower sensitivity, yet higher specificity. There was little effect of patients' age and sex on the diagnostic performance of CT, however, there was more effect on modified Alvarado score, (the area under ROC curve was the least in aged women). Conclusion:The performance of CT was better than that of modified Alvarado score for the diagnosis of acute appendicitis. Modified Alvarado score should be a supplementary approach fcr CT,especially in aged women.
