摘要
目的:探讨水灌肠超声联合剪切波弹性成像(SWE)技术在结肠良恶性肿物中的诊断价值.方法:选取2021年2月至2022年8月汕头大学医学院第二附属医院水灌肠超声检查中发现肿物的63例患者,采用SWE技术分别对肿物进行点式剪切波弹性成像(pSWE)及二维剪切波弹性成像(2D-SWE),获取剪切波速度(SWV),根据病理结果将其分为良性组(20例)和恶性组(43例),绘制受试者工作特征(ROC)曲线,预测结肠恶性病变SWV的临界值,比较2D-SWE杨氏模量平均值(Emean)、最小值(Emin)及最大值(Emax).结果:恶性组SWV值明显高于良性组,由ROC曲线可知,在2D-SWE,当SWV截断值分别为1.945 m/s、1.485 m/s和2.445 m/s,Emean、Emin及Emax的ROC曲线下面积(AUC)最大,其中Emax的灵敏度和特异度最佳,分别为95.3%和95%;而pSWE只存在平均值,当SWV截值为1.885 m/s,AUC最大.两组2D-SWE的Emean与pSWE均具有相关性,良恶性组的相关系数分别为0.725、0.803.结论:水灌肠超声联合SWE的客观量化指标,对鉴别肠道良恶性病变有较高的参考价值,且无创、依从性好,值得临床应用.
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.
