Abstract:
Objective:To investigate the diagnostic value of hydrocolonic sonography combined with shear-wave elastography(SWE)for benign and malignant tumors of colon.Methods:A total of sixty-three patients with tumor,who were confirmed by hydrocolonic sonography in the Second Affiliated Hospital of Shantou University Medical College from February 2021 to August 2022,were selected.The point-type SWE(pSWE)and two-dimensional SWE(2D-SWE)were performed on the tumors by SWE technique,respectively,to obtain shear wave velocity(SWV).And then,they were divided into benign group(N=20)and malignant group(N=43)according to pathological results.Receiver operating characteristic(ROC)curve was constructed to predict the SWV critical value of malignantly colonic lesions.In addition,the mean(Emean),the minimum value(Emin)and the maximum value(Emax)of Young's modulus between two groups were compared.Results:The SWV value of malignant group was significantly higher than that of benign group.The results of ROC curve of 2D-SWE indicated that the values of area under curve(AUC)of Emean,Emin and Emax were maximum when the SWV cutoff values were respectively 1.945 m/s,1.485 m/s and 2.445 m/s.Among of them,the sensitivity and specificity of Emax were the best,which were respectively 95.3%and 95%.However,the pSWE only had mean,which AUC was the biggest when SWV cutoff value was 1.885 m/s.There were correlations in both two groups between Emean and pSWE,and the correlation coefficients of benign and malignant groups were respectively 0.725 and 0.803.Conclusion:Hydrocolonic sonography combined with SWE technique is an objective and quantitative index,which has higher reference value for differentiating benign and malignant intestinal lesions.It is non-invasive and it has good compliance,which is worthy in clinical application.
