Establish the sensibility and specificity of the neutrophil-lymphocyte rate (NLR) in pediatric patients with acute complicated appendicitis.
Transversal, observational, descriptive, and retrospective study of pediatric patients between 4 to 16 years old with diagnosis of acute appendicitis, who had appendectomy, from December 2017 to January 2019. We calculated the NLR in every patient. To analyze the variables, we used the test of Mann-Whitney and we value the sensibility and specificity of the NLR.
There were 245 patients, 81 with simple appendicitis and 144 with complicated appendicitis. Just 27 of them were laparoscopic appendectomy. The NLR had a media of 10.48 in simple appendicitis, and 13.03 in complicated ones, with a p value of 0.02. the area under the curve was 0.622. There was a rate of 8.2 in complicated appendicitis to the NLR.
The NLR has been poorly studied in pediatric patients with acute appendicitis. In this study the NLR had a significant value in the patients with acute complicated appendicitis, with medium sensibility and a relatively low specificity.
确定中性粒细胞与淋巴细胞比值（NLR）在儿科急性复杂性阑尾炎患者中的敏感性和特异性。
这是一项回顾性、观察性、描述性的横断研究，研究对象为 2017 年 12 月至 2019 年 1 月期间，4 至 16 岁诊断为急性阑尾炎且接受阑尾切除术的儿科患者。我们计算了每位患者的 NLR。为了分析变量，我们使用了曼-惠特尼检验，并评估了 NLR 的敏感性和特异性。
共有 245 例患者，81 例为单纯性阑尾炎，144 例为复杂性阑尾炎。其中只有 27 例接受了腹腔镜阑尾切除术。单纯性阑尾炎患者的 NLR 中位数为 10.48，复杂性阑尾炎患者的 NLR 中位数为 13.03，p 值为 0.02。曲线下面积为 0.622。复杂性阑尾炎患者的 NLR 发生率为 8.2%。
NLR 在儿科急性阑尾炎患者中的研究较少。在本研究中，NLR 在急性复杂性阑尾炎患者中有显著意义，其敏感性中等，特异性较低。
