The accuracy of the modified Alvarado score was assessed prospectively in the preoperative diagnosis of acute appendicitis in children. A consecutive series of 118 patients (54 boys, 64 girls) with acute abdominal pain was studied prospectively over a 6 month period. Appendicitis was confirmed in 38 of 43 children undergoing appendicectomy, giving a false-positive appendicectomy rate of 11.6%. No child under active observation was subsequently found to have a perforated appendix. The overall sensitivity of a modified Alvarado score of > or = 7 was 76.3% and its specificity was 78.8%. Current clinical practice is more accurate than the modified Alvarado score in the diagnosis of acute appendicitis in children.
前瞻性评估改良阿瓦拉多评分在儿童急性阑尾炎术前诊断中的准确性。在6个月的时间里,对连续的118例急性腹痛患者(54名男孩,64名女孩)进行了前瞻性研究。43例行阑尾切除术的儿童中有38例确诊为阑尾炎,假阳性阑尾切除率为11.6%。随后未发现接受积极观察的儿童患有阑尾穿孔。改良阿瓦拉多评分≥7时的总体敏感度为76.3%,特异度为78.8%。在儿童急性阑尾炎的诊断中,目前的临床实践比改良阿瓦拉多评分更准确。
