BACKGROUND
Appendicitis is one of the most common abdominal emergency. Some predictive scoring systems are recommended to decrease the rate of negative appendectomy.
AIM
To evaluate sensitivity, specificity, positive predictive value, and negative predictive value of modified Alvarado score in children who underwent appendectomy.
METHODS
Four hundred children with initial diagnosis of appendicitis were randomly selected from patients who underwent appendectomy. Modified Alvarado score was used for evaluation of the appendicitis, that was confirmed using histology.
RESULTS
Of modified Alvarado score components, anorexia; nausea and vomiting and rebound tenderness were significantly more common in children with positive appendectomy in contrast to patients with negative appendectomy. Sensitivity, specificity, positive predictive value, and negative predictive value for modified Alvarado score were: 91.3%; 38.4%; 87.7%; and 51.2% respectively.
CONCLUSION
Alvarado score has high sensitivity but low specificity for diagnosis of acute appendicitis in children.
背景
阑尾炎是最常见的腹部急症之一。推荐使用一些预测评分系统以降低阴性阑尾切除术的发生率。
目的
评估改良阿尔瓦拉多评分在接受阑尾切除术儿童中的敏感性、特异性、阳性预测值和阴性预测值。
方法
从接受阑尾切除术的患者中随机选取400例初步诊断为阑尾炎的儿童。使用改良阿尔瓦拉多评分评估阑尾炎，并通过组织学检查进行确诊。
结果
在改良阿尔瓦拉多评分的各项指标中，与阴性阑尾切除术患者相比，厌食、恶心呕吐和反跳痛在阳性阑尾切除术儿童中更为常见。改良阿尔瓦拉多评分的敏感性、特异性、阳性预测值和阴性预测值分别为：91.3%、38.4%、87.7%和51.2%。
结论
阿尔瓦拉多评分对儿童急性阑尾炎的诊断具有高敏感性但特异性较低。
