RDW与不同类型急性阑尾炎的相关性分析

The correlation between RDW and different types of acute appendicitis

目的探讨红细胞分布宽度(RDW)与不同病理类型急性阑尾炎(AA)的相关性。方法按照病理类型将AA患者分为单纯性、化脓性以及坏疽性三种病理类型的AA患者,将这三组患者的RDW均值进行两两比较,并分别与对照组进行比较。分析三类AA患者的RDW值与白细胞(WBC)计数的相关性,应用ROC曲线分析RDW对于不同类型AA的诊断价值。结果单纯性和化脓性AA患者的RDW值与对照组比较差异有统计学意义(P<0.05),而与WBC计数无相关性(P>0.05);坏疽性AA的RDW值与对照组比较差异无统计学意义(P>0.05),而与WBC计数呈正相关(r=0.646,P<0.05)。结论 RDW与单纯性和化脓性AA存在相关性,RDW的降低可以对单纯性AA和化脓性AA的诊断提供参考,但尚不能作为单纯性AA和化脓性AA诊断的指标。

Objective the purpose of this study is to investigate the correlation of RDW and different pathological types of acute appendicitis（AA）.Methods According to the pathological classification,AA can be divided into pure,suppurative and gangrenous AA.The RDW values were compared among the 3kinds of AA patients,and compared with control group.Correlation analysis were performed in patients with the 3types of AA respectively.ROC was used to analyse RDW′s the diagnosic value for different types of AA.Results In patients with pure and suppurative AA,RDW values were statistically different from those in control group（P〈0.05）,and weren′t correlated with WBC count（P〉0.05）;while in patients with gangrenous AA,RDW values were not statistically different from those in control group,and were positively correlated with WBC count（r=0.646,P〈0.05）.Conclusion The decline RDW is correlated with simple and suppurative AA,and can provide some reference for the diagnosis of simple and suppurative AA,but not be used as diagnostic indicator because the sample quantity is not enough in the study.
