本文分析了158例老年便血者的病因,发现老年人大肠癌及腺瘤性息肉的检出率明显高于对照组,以直肠和乙状结肠居多;腺瘤性息肉随年龄增长检出率增高,呈多发倾向,易复发;对腺瘤患者定时复查,早发现,早摘除对防治大肠癌有重要意义.

158 aged patients with bloody stool were studied and compared with the control group. The incidence of colorectal cancer was abviously quite high, which accounted for 38.6% of the 158 aged patients. Polyps were detected in 29.8%, of which adenomas accounted for 76.7%. Multiple polyps were revealed in 42.6% of the patients with polyps. It is suggested that bloody stool in aged patients should be examined thoroughly. Removal of polyps is important for preventing colorectal cancer.
