目的 :研究结肠息肉的分布、发病年龄、病理类型及与息肉恶变的关系。方法 :对本院肠镜室 1 998年 1月～ 2 0 0 2年 1 2月检出并经病理证实的结肠、直肠息肉 1 2 0 4例进行分析。结果 :结肠、直肠息肉分布部位以左半结肠 ,尤其是直肠和乙状结肠为多。息肉好发年龄为 41～ 70岁。息肉的类型以腺瘤性息肉最多 (占55 .32 % ) ;腺瘤性息肉恶变率高 (6 .61 % ) ,其中尤以绒毛状腺瘤更易恶变 ;恶变部位以直肠息肉最多(1 1 .1 9% )。结论 :结肠、直肠息肉好发于直肠和乙状结肠 ;腺瘤性息肉发病率高且易恶变
Objective: To study the distribution of colonic polyps, the age of onset, the pathological types and the relationship between polyps and malignant transformation. Methods: A total of 1204 cases of colon and rectum polyps detected in our hospital from January 1998 to January 2012 were retrospectively analyzed. Results: Colon, rectum polyps distributed to the left half of the colon, especially the rectum and sigmoid colon as much. Polyps predilection age of 41 to 70 years old. The most common types of polyps were adenomatous polyps (55.32%). The adenomatous polyps were highly malignant (6.61%), of which villous adenomas were more likely to degenerate. The malignant sites were the most with polyps .1 9%). Conclusion: Colon and rectal polyps occur in the rectum and sigmoid colon. The incidence of adenomatous polyps is high and easily malignant
