摘　　要：目的探究经直肠腔内双平面超声联合MRI在直肠癌术前T分期中的应用价值。方法选取2021年1月~2023年1月我院收治90例直肠癌患者作为研究对象,所有患者均进行经直肠腔内双平面超声联合MRI检查。以病理结果为“金标准”,评估经直肠腔内双平面超声联合MRI在直肠癌术前T分期中的应用价值。结果在90例直肠癌患者中,以“金标准”为基础,术后分期PT1为10例;PT2为23例;PT3为38例;PT4为19例。单独使用经直肠腔内双平面超声诊断UT1准确率为60.00%;UT2准确率为65.21%;UT3准确率为81.57%;UT4准确率为84.21%;总体准确率为90.00%。单独使用MRI诊断T1准确率为70.00%;T2准确率为69.56%;T3准确率为86.84%;T4准确率为78.94%;总体准确率为88.88%。经直肠腔内双平面超声联合MRI诊断结果显示,UT1准确率为50.00%;UT2准确率78.26%;UT3准确率为76.31%;UT4准确率为89.47%;总体准确率为91.11%。二者联合检测的灵敏度、特异度和准确度均较高于经直肠腔内双平面超声、MRI单项检测,对直肠癌检出率较高,诊断价值较好,具有统计学差异(P<0.05)。结论在直肠癌的术前分期诊断中应用经直肠腔内双平面超声联合MRI,具有较高的准确性,对制定手术方案和患者预后都有重要意义,值得临床推广应用。Objective To explore the application value of transrectal biplanar ultrasound combined with MRI in preoperative T staging of rectal cancer.Methods A total of 90 patients with rectal cancer admitted to our hospital from January 2021 to January 2023 were selected as the study objects.All patients underwent transrectal biplanar ultrasound combined with MRI.To evaluate the value of transrectal biplanar ultrasound combined with MRI in preoperative T staging of rectal cancer using pathological results as the gold standard.Results In 90 cases of rectal cancer patients,based on the"gold standard",10 cases of postoperative stage PT1;PT2 was found in 23 cases.PT3 was found in 38 cases.There were 19 cases with PT4,and the accuracy of UT1 diagnosis was 60.00%by transrectal biplanar ultrasound alone.The accuracy of UT2 was 65.21%.UT3 accuracy was 81.57%;The accuracy of UT4 was 84.21%;The overall accuracy was 90.00%.The accuracy rate of T1 diagnosis by MRI alone was 70.00%.T2 accuracy was 69.56%;The accuracy of T3 was 86.84%;T4 accuracy rate was 78.94%;The overall accuracy was 88.88%.The accuracy rate of UT1 was 50.00%.UT2 accuracy 78.26%;The accuracy of UT3 was 76.31%.The accuracy of UT4 was 89.47%.The overall accuracy was 91.11%.The sensitivity,specificity and accuracy of the combined detection of the two methods were higher than that of the single detection of transrectal double-plane ultrasound and MRI,and the detection rate of rectal cancer was higher and the diagnostic value was better,with statistical difference(P<0.05).Conclusion The application of transrectal biplanar ultrasound combined with MRI in the preoperative staging diagnosis of rectal cancer has high accuracy,and is of great significance for the formulation of surgical plan and the prognosis of patients,and is worthy of clinical application.
