The role of the double-contrast enema examination (DCE) in the detection of rectal carcinoma was evaluated and compared to the proctoscopic examination. Records of 90 consecutive patients with a diagnosis of rectal carcinoma were reviewed. Sixty-six patients had a preoperative DCE. The correct diagnosis was either made or suggested in 91% of these patients. The proctoscopic examination was diagnostic in 86%. The causes of radiologic and proctoscopic error were evaluated. Findings confirm that the DCE is an accurate method for the diagnosis of rectal carcinoma. Careful examination of the rectum should be incorporated in all radiologic studies of the colon since a normal proctoscopic examination does not exclude the possibility of rectal carcinoma.
评估了双重对比灌肠检查（DCE）在直肠癌检测中的作用，并与直肠镜检查进行了比较。回顾了90例连续诊断为直肠癌患者的记录。66例患者术前行DCE检查。其中91%的患者做出了正确诊断或提示了正确诊断。直肠镜检查的诊断率为86%。评估了放射学和直肠镜检查错误的原因。研究结果证实，DCE是诊断直肠癌的一种准确方法。在所有结肠放射学检查中都应仔细检查直肠，因为直肠镜检查正常并不能排除直肠癌的可能性。
