二维超声剪切波弹性成像及频散成像在诊断代偿期肝硬化高风险食管胃静脉曲张中的临床价值

The Clinical Value of Two-Dimensional Ultrasound Shear Wave Elastography and Dispersion Imaging in the Diagnosis of High-Risk Esophageal and Gastric Fundal Varix in Compensatory Cirrhosis

目的:分析代偿期肝硬化高风险食管胃底静脉曲张诊断中应用二维超声诊断剪切弹波成像与频散成像的临床价值。方法:以2022年1月~2023年8月本院接诊的100例代偿期肝硬化患者为观察对象,在胃镜前对全部患者分别予以二维超声剪切波弹性成像与频散成像,基于胃镜诊断结果,评价两种成像方案对于高风险食管胃底静脉曲张的筛查预测诊断效能。结果:在高风险食管胃底静脉曲张的筛查预测诊断中,剪切波频散成像的诊断灵敏度、特异性、阳性预测值、阴性预测值高于对照组,组间差异具有统计学意义(P<0.05)。结论:在代偿期肝硬化高风险食管胃底静脉曲张预测分析中,二维超声剪切波频散成像较弹性成像的预测效能较佳,其可在一定程度上预测食管胃底静脉曲张的发生。

Objective:To analyze the clinical value of two-dimensional ultrasonic shear wave elastography(SWE)and dispersion imaging in the diagnosis of high-risk esophageal and gastric fundal varix(HR-EGFV)in patients with compensated cirrhosis.Methods:A total of 100 patients with compensated cirrhosis admitted to our hospital from January 2022 to August 2023 were enrolled as subjects.All patients underwent two-dimensional ultrasonic SWE and dispersion imaging before gastroscopy.Based on the gastroscopy results,the diagnostic efficacy of the two imaging modalities for screening and predicting HR-EGFV was evaluated.Results:In the screening and prediction of HR-EGFV,SWE demonstrated higher diagnostic sensitivity,specificity,positive predictive value,and negative predictive value compared to the control group,with statistically significant differences between the groups(P<0.05).Conclusion:In the predictive analysis of HR-EGFV in patients with compensated cirrhosis,two-dimensional ultrasonic shear wave dispersion imaging exhibits superior predictive performance compared to elastography.It can predict the occurrence of esophageal and gastric varices to some extent.
