A total of 210 patients was examined by barium enema and colonoscopy. The authors found 219 polyps in 112 patients. Single-contrast barium enema missed 33 (45.2%) and double-contrast barium enema missed 17 (11.7%) polyps. Colonoscopy failed to detect 6 polyps (2.7%) and another 21 (10%) were not seen because the area could not be reached by the colonoscope. Malignancy was present in 5 small polyps. The authors conclude that the double-contrast barium enema offers a definite advantage in the right colon. In general, the two methods are complementary.
共有210例患者接受了钡灌肠和结肠镜检查。作者在112例患者中发现了219个息肉。单对比钡灌肠漏诊了33个息肉（45.2%），双对比钡灌肠漏诊了17个息肉（11.7%）。结肠镜检查未能检测到6个息肉（2.7%），另有21个息肉（10%）未被发现是因为结肠镜无法到达该区域。5个小息肉存在恶性病变。作者得出结论，双对比钡灌肠在右半结肠具有明显优势。总体而言，这两种方法是互补的。
