Abstract:
ObjectiveTo investigate the clinical value of acoustic radiation force impulse (ARFI) elastography in predicting esophageal variceal bleeding in patients with liver cirrhosis. MethodsA retrospective analysis was performed for the clinical data of 271 patients with liver cirrhosis who attended the Fifth Medical Center of Chinese PLA General Hospital from October 2014 to May 2017, and ARFI elastography was performed for all patients to measure the elasticity of the liver and the spleen. According to the presence or absence of esophageal variceal bleeding, the patients were divided into bleeding group and non-bleeding group, and related indices were compared between the two groups. The receiver operating characteristic (ROC) curve was used to evaluate the value of ARFI elasticity in the diagnosis of esophageal variceal bleeding in liver cirrhosis. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. ResultsThe bleeding group had a significantly higher ARFI elasticity of the spleen than the non-bleeding group ［3.89(349-4.11) m/s vs 3.46(2.93-3.80) m/s, Z=-4.941, P＜0.001］, and there was no significant difference in the ARFI elasticity of the liver between the bleeding group and the non-bleeding group ［2.08 (1.57-2.74) m/s vs 1.98 (1.49-2.70) m/s, Z=-1.025, P=0.305］. The areas under the ROC curve for ARFI elasticity values of the spleen and the liver were 0.714 and 0.544, respectively, in predicting esophageal variceal bleeding in patients with liver cirrhosis (P=0.002 5). At the cut-off value of 3.71 m/s, the ARFI elasticity of the spleen had a sensitivity of 0.68 and a specificity of 0.69 in predicting esophageal variceal bleeding. ConclusionThe ARFI elasticity value of the spleen has a better value than that of the liver in predicting the risk of esophageal variceal bleeding and thus holds promise for clinical application.
