The need for colonoscopic examination of the whole colon was determined by evaluating the accuracy of a barium enema X-ray report with particular reference to the right colon. Long colonoscopies were performed on 108 patients. The reports of the barium enema X-ray examination in these patients were compared with the colonoscopy reports. Over all, the barium enema X-ray report was accurate in 47% of cases. The rate of false negative reports was 10% and that of false positive reports 43%. For lesions of the right colon, the barium enema X-ray report was accurate in only 32% of cases, with 68% false positive and 15% false negative reports. False positive reports of carcinoma or polyps result mainly from imperfect preparation. Of the eight right colonic lesions missed in the barium enema X-ray examination, five were polyps and one was carcinoma. Long colonoscopy, rather than short colonoscopy, or flexible sigmoidoscopy and barium enema X-ray examination, would be accompanied by the greatest diagnostic accuracy. Air-contrast barium enema X-ray examination and long colonoscopy together offer the best methods of diagnosis of occult lesions in the right colon.
通过评估钡剂灌肠X线报告（特别是针对右半结肠）的准确性来确定对全结肠进行结肠镜检查的必要性。对108例患者进行了全结肠镜检查。将这些患者的钡剂灌肠X线检查报告与结肠镜检查报告进行比较。总体而言，钡剂灌肠X线报告在47%的病例中是准确的。假阴性报告率为10%，假阳性报告率为43%。对于右半结肠病变，钡剂灌肠X线报告仅在32%的病例中准确，假阳性报告率为68%，假阴性报告率为15%。癌或息肉的假阳性报告主要源于准备不充分。在钡剂灌肠X线检查中漏诊的8例右半结肠病变中，5例为息肉，1例为癌。全结肠镜检查，而非短结肠镜检查、可曲式乙状结肠镜检查和钡剂灌肠X线检查，具有最高的诊断准确性。气钡双重造影X线检查和全结肠镜检查共同提供了诊断右半结肠隐匿性病变的最佳方法。
