The authors report a comparative study between endorectal ultrasonography (EU) and computed tomography (CT) in the preoperative assessment of 94 patients with rectal cancer. In evaluating the depth of wall penetration of rectal tumors EUS and CT offered good results: EUS confirmed a clear superiority with overall accuracy of 88.4% versus 80% of CT. On the contrary, in detecting lymph node metastases both techniques had poor results obtaining a correct diagnosis in 75.6% of the cases with EUS and in 69.4% of the cases with CT. In conclusion, the authors believe that EUS and CT may by very useful in the study of tumor penetration of the rectal wall; while in the study of lymph node involvement new techniques for a more accurate diagnosis are needed.
作者报告了一项针对94例直肠癌患者术前评估的直肠内超声检查（EU）与计算机断层扫描（CT）的对比研究。在评估直肠肿瘤的壁层浸润深度方面，EUS和CT均取得了良好的结果：EUS显示出明显优势，总体准确率为88.4%，而CT为80%。相反，在检测淋巴结转移方面，两种技术的结果均较差，EUS在75.6%的病例中获得正确诊断，CT在69.4%的病例中获得正确诊断。总之，作者认为EUS和CT在研究直肠壁肿瘤浸润方面可能非常有用；而在研究淋巴结受累情况时，需要新技术以获得更准确的诊断。
