息肉与癌的密切关系早已受到重视,一般认为其癌变率为1～3％,腺瘤性息肉中增生的进展程度与癌的生化特征紧密相关,有腺瘤-癌顺序的理论。在息肉生长时间长、多发性,>2 cm、特别是进行性增大,形态异常、广基底、粘膜色泽改变以及息肉与附近粘膜界线不清等提示恶变。因此内镜下切除息肉的临床意义可用Gilbersten的研究中已得出足够证据,显示癌症的预期发生率减少85％。我院自1987年7月～1988年6月,用日产Qlympus GIFXQ_(10)、CFIBW、国产X_(S-4),
The close relationship between polyps and cancer has long been valued. It is generally believed that the cancerous rate is 1-3%. The degree of progression of hyperplasia in adenomatous polyps is closely related to the biochemical characteristics of cancer, and there is a theory of adenoma-cancer sequence. In the polyp growth time is long, multiple,> 2 cm, especially progressive increase, abnormal morphology, wide base, changes in mucosal color, as well as polyps and the surrounding mucosal borders are not clear and other indicators of malignant transformation. Therefore, the clinical significance of endoscopic resection of polyps can be sufficiently evidenced in Gilbersten’s study, which shows that the expected incidence of cancer is reduced by 85%. In our hospital from July 1987 to June 1988, we used Nissan Qlympus GIFXQ_(10), CFIBW, domestic X_(S-4),
