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
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
