1975～1987年我院大肠检查便血者1493例,其中65岁以上者158例(10.6%),并与同期幼年组、青年组和中年组对照,探讨了老年人便血的原因和诊治方法。158例便血期为1周至10年,便血疫病迭13种之多。其中大肠癌61例(38.6%),显著高于对照组;次为大肠息肉47例(29.7%),显著低于幼年组和青年组,与中年组无明显差异。大肠癌与大肠息肉呈正相关,90.1%和70.2%分布于直肠和乙状结肠。大肠癌术后随访显示A期和B期的5年存活率显著高于C期和D期。腺瘤样息肉随访对防治早期大肠癌有重要意义。
From 1975 to 1987, 1493 cases of blood in the stool were examined in our hospital, of whom 158 (10.6%) were over 65 years of age. They were compared with the young, youth, and middle-aged groups in the same period. The causes and diagnosis and treatment of blood in the elderly were discussed. 158 cases of blood in the stool are from 1 week to 10 years, and there are as many as 13 kinds of blood-borne diseases. Among them, 61 cases (38.6%) of colorectal cancer were significantly higher than those in the control group, and 47 cases (29.7%) of colorectal polyps were significantly lower than those in the juvenile and youth groups. There was no significant difference from the middle-aged group. Colorectal cancer was positively correlated with colorectal polyps, with 90.1% and 70.2% in the rectum and sigmoid colon. Follow-up of colorectal cancer showed that the 5-year survival rate of A and B phases was significantly higher than that of C and D phases. Follow-up of adenoma-like polyps is important for prevention and treatment of early colorectal cancer.
