1980～1985年用纤维结肠镜进行直肠乙状结肠癌普查4,219例,检出大肠癌5例(早期癌2例,进展癌3例)检出率为0.12％。同时检出大肠息肉160例,占3.79％。其中腺瘤86例,有3例伴重度不典型增生,均在内窥镜下摘除。本文探讨了大肠癌普查价值、方法、对象的选择(年令、症状、高危人群),普查中的几个问题(镜型、术前准备、检查法),并提出今后普查的设想:小组人群仍采用现
From 1980 to 1985, 4,219 cases of rectal sigmoid colon cancer were examined by colonoscopy. The detection rate of colorectal cancer in 5 cases (2 cases with early cancer and 3 cases with advanced cancer) was 0.12%. At the same time, 160 cases of colorectal polyps were detected, accounting for 3.79%. Of these, 86 were adenomas, and 3 were associated with severe dysplasia. All were removed under endoscopy.
