摘 要:目的探索老年及老年前期大肠疾病的发病特点,方法对1391例大肠活检标本进行了回顾性分析。结果老年组、老年前期组及青年组慢性结肠炎的检出率随年龄增长而依次递减(P<0.05,r=-0.8876);溃疡性结肠炎的检出率亦随年龄增大而降低(P<0.01,r=-0.9969);肠息肉的检出率在各年龄组间无明显差异;肠腺瘤及腺瘤伴异型增生的检出率随年龄的增长而增加(P<0.01,r=0.9954和P<0.01,r=0.9966);大肠癌的检出率随年龄增大而增加(P<0.01,r=0.9344)。结论随着年龄的增加,肠腺瘤、异型增生及大肠癌的发生率逐渐上升,而慢性结肠炎、溃疡性结肠炎的发病则逐渐下降。Objective To discuss the characteristic of the elderly and presenlie. Methods Reviewing 1391 biospys of large intestine using χ2 ang regression. Results The eldery pateints had the lower incidence rate of chronic colitis(P<005,r=08876).The ulcerative colitis was simlar to chronic colitis(P<001,r=09969).The polyps were not related to age and sex(P>005).The incidence rates of adenoma and adenoma with dysplasia of the large bowel were increased when the patient got old (P<001,r=09954 and P<001,r=09966).The large bowel carcinoma was found more and more when the age increases (P<001,r=09344). Conclusions The rates of adenoma,dysplasia and carcinoma of the large bowel gradually rose when the age increased,on the contrary those of chronic colitis and chronic ulcerative colitis were lower when the age increased.
