[目的]探讨1595例大肠息肉患者临床特征及结肠癌检出情况.[方法]收集接受肠镜检查并确诊为大肠息肉1595例(1805枚息肉)患者的临床资料,分析大肠息肉患者临床特征及其结肠癌检出情况.[结果]不同性别大肠息肉患者年龄分布比较差异无显著性(P>0.05),大肠息肉患者所占比例随年龄增长呈递增趋势,41~50岁患者比例明显升高,以>60岁患者最高,与≤40岁患者相比差异有显著性(P<0.05).1805枚息肉中腺瘤性息肉占55.01%(993/1805)高于非腺瘤性44.99%(812/1805)(P<0.05);升结肠、降结肠、横结肠、乙状结肠及直肠部位以腺瘤性息肉为主,回盲部以非腺瘤性息肉为主,两者相比较差异均有显著性(P<0.05).共检出结肠癌304例(312枚息肉),检出率为19.06%.大肠息肉癌变患者与无癌变患者其年龄、息肉大小、病理类型、息肉部位比较差异有显著性(P0.05).The proportion of patients with color-ectal polyps increased with the increase of age,and the proportion in 41~50 years old was significantly higher. Compared with patients ≤ 40 years old(P 60 years old was the high-est.Among the 1805 polyps,there were 993(55.01%)adenomatous polyps,which was more that the non ade-nomatous polyps 812(44.99%)(P<0.05).The polyps in ascending,descending,transverse and sigmoid co-lon and rectum were adenomatous polyps mainly,while polyps at ileocecus were non adenomatous polyps mainly,there were significant differences between the two(P<0.05).There were 304 cases with colon canc-er(312 polyps)detected,and the detection rate was 19.06%.There were significant differences in age,polyp size,pathological types and polyp location between patients with canceration of colorectal polyps and those without canceration(P<0.01).[Conclusion] The risk of colorectal polyps increases with the increase of age. The adenomatous polyps in the ascending,descending,transverse and sigmoid colon and rectum and non ade-nomatous polyps at ileocecus are common.Advanced age,large polyps,adenomatous polyps in the ascending colon and rectum can increase the risk of colon cancer.
