We had conducted fibrocolonoscopy in 205 elders with lower digestive tract hemorrhage.According to the frequency.the causes were listed as:colorectal carcinoma (84 cases),chronic colitis (46 cases),colorectal polyps (38 cases),ulcerative colitis (19 cases),Crohn Diseases (1 cases),deformation of colon vessels (2 cases),other colorectal diseases (4 cases).No cause was found in 11 cases.The rate of dignosis was 94.6%.Most of the colorectal carcinoma and polyps were in left colon,which accounted for seperately 79.8% and 73.7% in total cases.11 cases of polyps had cancer tendency,and 12 cases had both carcinomas and polyps.To prevent polyps from changing into cancer,the colon polyps in elders should be resected by electrocoagulation.
