摘要
目的 探讨大肠息肉的内镜下表现与病理特征及其恶变的关系。方法 对门诊患者大肠镜普查发现的 36 1例大肠息肉的内镜及病理特征作回顾性分析。结果 息肉恶变 42例 42枚 (10 5 % )。息肉≤ 5mm者无恶变 ,6～ 9mm者恶变率 0 9% ,10～ 19mm者恶变率 11 8% ,≥ 2 0mm者恶变率 38 5 % ;腺瘤性息肉恶变率 9 7% ,增生性息肉恶率4 5 % ,80例炎性息肉有 1例恶变。绒毛状腺瘤性息肉是息肉恶变的高危因素 ,恶变率 (19/ 80 ) 2 3 8% ;恶变的息肉内镜下均表现为宽蒂或无蒂 ,表面充血或糜烂。结论 息肉恶变与其大小、形态和组织病理类型相关 ,腺瘤性息肉体积越大 ,绒毛状结构越多 ,癌变机会越高 ;增生性息肉、炎性息肉亦有恶变 ;大肠息肉不论大小、性质应尽可能予以切除。
Objective\ To investigate the location, size, morphology and histopathology of colorectal polyps and the correlation of which with canceration. Methods\ The documents of 361 patients with bowel polyps detected by screening colonoscopy performed on 2 764 consulting patients from 1995 to 1998 were retrospectively reviewed and analyzed. Results\ Forty two polyps with malignent change in 42 patients were found. The rate of malignent change from benign seemed dependent on its size, morthology and type of histopathology, being≤5 mm, 0%; 6～9 mm, 0.9%; 10～19 mm,11.8%;≥20 mm, 38.5%;adenoma,9.7%;hyperplastic polyp,4.5%; inflammantory polyp, 1/80; villous adenoma, 23.8%. Conclusion\ Polyp with bigger valume, more villous structure has more crisis of malignent change. Hyperplastic polyp and inflammantory polyp have also malignent change. Colorectal polyps is to be extirpated regardless of size and type.
