One thousand forty-eight small (up to 6 mm) colorectal polyps, removed during colonoscopy, have been analyzed. Sixty-one percent of these small polyps were neoplastic, the remainder being equally divided between hyperplastic polyps and polypoid mucosa with normal-appearing glands. The number of polyps was evenly distributed throughout the colon. Proximally, neoplastic polyps predominated, accounting for 73% of all polyps in the right colon. This was reversed in the distal colon where non-neoplastic polyps comprised 65% of all polyps in the rectum. The incidence of carcinoma was extremely low in small colon polyps, 0.1%. All polyps should be removed when encountered during colonoscopy due to the high prevalence of adenomas among small colon polyps.
对在结肠镜检查期间切除的1048个小（最大6毫米）结直肠息肉进行了分析。这些小息肉中有61%为肿瘤性息肉，其余的在增生性息肉和具有外观正常腺体的息肉样黏膜之间平均分布。息肉数量在整个结肠中均匀分布。在近端，肿瘤性息肉占主导，占右半结肠所有息肉的73%。在远端结肠情况则相反，非肿瘤性息肉占直肠所有息肉的65%。小结肠息肉的癌变发生率极低，为0.1%。由于小结肠息肉中腺瘤的高患病率，所有息肉在结肠镜检查时遇到都应予以切除。
