摘要

目的比较血小板计数与脾面积比值（PC/SA）和血小板计数与脾长径比值（PC/SD）诊断乙肝肝硬化患者食管静脉曲张（EV）的价值。方法选取在我院就诊的172例乙肝肝硬化患者

根据胃镜检查结果分为EV组121例和无EV组51例

均行胃镜、血常规及腹部超声检查

采集血小板计数（PC）、脾长径、脾厚径

计算PC/SA和PC/SD。绘制受试者工作特征（ROC）曲线评价PC/SA、PC/SD诊断EV的价值

比较两者诊断效能。结果 EV组脾长径和脾厚径均大于无EV组

EV组PC、PC/SA及PC/SD均小于无EV组（均P<0.001）。PC/SA诊断EV的曲线下面积（AUC）为0.846（95%可信区间:0.784～0.897）

截断值为10.29时

其诊断敏感性、特异性、阳性预测值及阴性预测值分别为79.4%、76.5%、88.9%、60.9%;PC/SD诊断EV的AUC为0.816（95%可信区间:0.750～0.871）

截断值为629.65时

其诊断敏感性、特异性、阳性预测值及阴性预测值分别为87.6%、64.7%、85.5%、68.7%。PC/SA诊断EV的AUC高于PC/SD（0.846 vs.0.816

Z=2.954

P=0.003）。结论 PC/SA与PC/SD均可用于诊断乙肝肝硬化患者EV

PC/SA诊断价值更高

具有较好的临床推广应用潜力。

Abstract

Objective To explore the value of platelet count/spleen area ratio（PC/SA）and platelet count/spleen diameter ratio（PC/SD）in the diagnosis of esophageal varices（EV）in patients with hepatitis B cirrhosis.Methods A total of 172 patients with hepatitis B cirrhosis were enrolled

they were divided into EV group（n=121）and no EV group（n=51）according to gastroscope

all of them were examined by gastroscope

blood routine examination and abdominal ultrasonography.Platelet count（PC）

spleen length diameter and spleen thickness diameter were measared.PC/SA and PC/SD were calculated.The value of PC/SA and PC/SD for diagnosis of EV was evaluated by receiver operating characteristic（ROC）curve. The diagnostic efficacy of PC/SA and PC/SD were compared.Results The spleen length diameter and spleen thickness diameter in EV group were significantly larger than those in no EV group

PC/SA and PC/SD in EV group were significantly lower than those in no EV group（all P<0.001）.The area under curve（AUC）of PC/SA for diagnosing EV was 0.846（95%CI:0.784～0.897）.When the cutoff value was 10.29

the sensitivity

specificity

positive predictive value and negative predictive value were 79.4%

76.5%

88.9% and 60.9%

respectively.The AUC of PC/SD for diagnosis of EV was 0.816（95%CI:0.750～0.871）.When the cutoff value was 629.65

the sensitivity

specificity

positive predictive value and negative predictive value were 87.6%

64.7%

85.5% and 68.7%

respectively.The AUC of PC/SA was higher than that of PC/SD（0.846 vs. 0.816

Z=2.954

P=0.003）.Conclusion PC/SA and PC/SD can be used to screen EV in patients with hepatitis B cirrhosis.PC/SA

with higher accuracy

is worthy of clinical attention and application.
