摘要 目的:探讨吉林地区〈10 mm的大肠小息肉的内镜、病理特点及临床意义。方法:根据息肉的大小将大肠小息肉分为〈6 mm小息肉组和6~10 mm小息肉组,对两组的病理类型、发病部位及单发还是多发进行分析,并将大肠小息肉分为肿瘤性和非肿瘤性息肉,分析两组中肿瘤性息肉所占的比例。在肿瘤性大肠小息肉中分别对两组中的"高危"肿瘤及癌所占比例进行分析。结果:1911枚大肠小息肉中肿瘤性息肉所占的比例为71%。与〈6 mm的大肠小息肉相比,6~10 mm的大肠小息肉中肿瘤性息肉所占的比例较高(84%)。在肿瘤性大肠小息肉中,6~10 mm的小息肉以多发息肉居多、"高危"肿瘤所占的比例较大(29%)及癌变率较高(2.5%)。肿瘤性息肉均好发于右袢结肠。总体上,"高危"肿瘤在大肠肿瘤性息肉中所占的比率是10%,癌在大肠肿瘤性息肉中的比率是0.9%。结论:〈10 mm的大肠小息肉中肿瘤性息肉及"高危"肿瘤所占的比率均较高,与〈6 mm的大肠小息肉相比,6~10 mm的大肠小息肉中肿瘤性息肉、高危肿瘤及癌变率均较高,所以发现大肠小息肉后应引起足够重视,尤其是6~10 mm的大肠小息肉发现后应尽早内镜下治疗。
