摘　　要：目的探讨经直肠双平面腔内超声在诊断直肠腺瘤局部恶变中的应用价值。方法应用彩色多普勒超声诊断仪经直肠双平面探头,对临床怀疑为直肠腺瘤局部恶变的37例老年患者进行检查,并将诊断结果与术后病理结果进行对比。结果 37例患者中,术后病理诊断直肠腺瘤局部恶变32例,超声诊断直肠腺瘤局部恶变29例。经直肠双平面腔内超声诊断直肠腺瘤局部恶变的准确率、敏感度、特异度、阳性预测值、阴性预测值、假阳性率、假阴性率分别为90.6%、90.6%、100%、100%、62.5%、0%、9.4%。结论经直肠双平面腔内超声对直肠腺瘤局部恶变的诊断准确率较高,可作为指导手术的首选方法。Objective To explore the clinical effectiveness of application of double-plane transrectal ultrasound in the diagnosis of carcinoma arising in the rectal adenoma. Methods Thirty-seven patients who were doubted having rectal carcinoma arising in the adenoma were examined by double-plane transrectal ultrasound and the results were compared with post-operation pathological diagnosis. Results Among the 37 patients, 32 cases were diagnosed as carcinoma arising in the adenoma by post-operation pathology, and 29 cases were diagnosed by double-plane transrectal ultrasound. There was no statistical significance between the two. The diagnose accuracy, sensitivity, specificity, the positive predictive value, the negative predictive value, the false positive rate and the false negative rate were 90.6%, 90.6%, 100%, 100%, 62.5%, 0% and 9.4% respectively. Conclusion Application of double-plane transrectal ultrasound showed high accuracy in diagnosis of carcinoma arising in the rectal adenoma, which should be the preferred method to guide the operation.
