对 14年间自 15 33例纤维结肠镜检查中检出大肠癌 89例进行回顾性分析。大肠癌检出率为 5 .81%。检出部位以直—乙结肠最多 ,占 80 .9% ,显示该肠段仍为最高发部位。多原发癌 2例。早癌未能检出。癌伴息肉占 30 .3%。年龄 >5 0岁占 79.8%。提示与体会 :放宽肠镜检查指征 ;重点监测高危人群 ;重视临床表现特征 ;强调直肠指诊 ;推崇全大肠镜检 ,以免遗漏多原发癌及癌前病变 ;积极处理腺瘤性息肉 ,提高早癌诊断水平。
A retrospective analysis was performed on 89 cases of colorectal cancer detected in fifteen hundred and thirty-three cases of colonoscopy. The detection rate of colorectal cancer was 5.81%. The most detected site was straight-eight colon, accounting for 80.9%, indicating that the intestinal segment was still the highest site. More than two primary cancers. Early cancer failed to be detected. Cancer with polyps accounted for 30.3%. Age >50 years accounted for 79.8%. Tips and experiences: Relaxation of colonoscopy indications; focus on monitoring high-risk groups; emphasis on clinical manifestations; emphasizing rectal examination; respect for colonoscopy to avoid missing multiple primary cancers and precancerous lesions; active treatment of adenomatous polyps, Improve early cancer diagnosis.
