摘　　要：目的:探讨大肠双重超声造影在结直肠病变诊断及结直肠癌TN分期中的临床应用价值。方法:回顾性选取2019年11月至2022年12月于某院收治的大肠双重超声造影结果阳性的479例患者的临床资料。以病理结果为金标准,统计大肠双重超声造影诊断结直肠病变及结直肠癌TN分期的分布情况,分析大肠双重超声造影诊断结直肠癌TN分期的临床诊断效能,并应用1VSRest策略绘制T、N分期模型诊断结直肠癌的ROC曲线。采用SAS 9.4统计学软件对数据进行分析。结果:纳入的479例患者中,病理诊断和超声诊断一致例数为462例,符合率为96.5%;结直肠癌427例,占比89.1%。在结直肠癌T1、T2、T3、T4a、T4b分期中,大肠双重超声造影诊断的准确率分别为96%、82%、63%、79%、97%,准确率的微平均值为83%。在结直肠癌N0、N1、N2分期中,大肠双重超声造影诊断的准确率分别为62%、68%、80%,准确率的微平均值为70%。T分期模型诊断结直肠癌的AUC微平均值为0.92,宏平均值为0.84;N分期模型诊断结直肠癌的AUC微平均值为0.88,宏平均值为0.85。结论:大肠双重超声造影是诊断结直肠病变的有效方法,为结直肠癌患者术前TN分期提供了重要的参考价值。Objective To investigate the clinical application value of colorectal double contrast-enhanced ultrasonography in diagnosing colorectal lesions and TN staging of colorectal cancer.Methods The clinical data of 479 patients with positive colorectal doulble contrast-enhanced ultrasonography results admitted to some hospital from November 2019 to December 2022 were selected retrospectively.The distributions of colorectal lesions and TN stages of colorectal cancer diagnosed by colorectal double contrast-enhanced ultrasonography were counted using the pathological results as the gold standard.The clinical diagnostic efficacy of colorectal double contrast-enhanced ultrasonography for TN staging of colorectal cancer was analyzed,and the ROC curves of the T and N staging models for diagnosing colorectal cancer were plotted by applying the 1VSRest strategy.SAS 9.4 statistical software was used to analyze the data.Results Among the 479 patients included,there were 462 cases in which the pathological diagnosis and ultrasound diagnosis were consistent with each other,with a compliance rate of 96.5%;there were 427 cases of colorectal cancer,accounting for 89.1%.Colorectal double contrast-enhanced ultrasonography had the accuracies being 96%,82%,63%,79%and 97%respectively for T1,T2,T3,T4a and T4b stages of colorectal cancer,with the micro-mean value of the accuracy being 83%.The accuracies were 62%,68%and 80%for N0,N1 and N2 stages of colorectal cancer,with the micro-mean value of the accuracy being 70%.The micro-mean value for T staing model to diagnose colorectal cancer was 0.92,and the macro-mean value was 0.84;the micro-mean value for N staing model to diagnose colorectal cancer was 0.88,and the macro-mean value was 0.85.Conclusion Colorectal doube contrast-enhanced ultrasonography is effective for diagnosing colorectal lesions,and provides references for TN staging of colorectal cancer.[Chinese Medical Equipment Journal,2024,45(7):62-66]
