老年人大肠息肉随访5年的临床病理特点

The Clinicopathologic Characteristics of Polyps of the Large Bowel Following up for Five Years in the Aged

分析56例老年人经纤维肠镜随访5年的649枚大肠息肉的临床病理特点,包括解剖部位、组织学分型及其与形态学的关系、动态变化及预后。认为老年人大肠息肉以多发性管状腺瘤为多见,每年动态观察结果变化不大,预后良好。少数绒毛状腺瘤伴不典型增生的恶性潜力较大,故老年人每年行肠镜检查是必要的。

Fifty-six cases of polyps of the large bowel in the aged were analysed clinicopathologically. In the study, colonoscopy were performed in all cases and followed up for five years or more. This report was an analysis of 649 polyps from 56 cases involving in anatomic distribution, histological types and their relation to morphology, development and prognosis. The results demonstrated that multiple tubular adenomas were common, there were no significant variations in pathological features during follow up each year and all had satisfied prognosis. A minority of villous adenomas with atypical hyperplasia was strongly associated with contiguous invasive carcinoma. It should be emphasized that colonoscopic examination was necessary for the aged each year.
