Abstract: 目的 对大肠侧向发育型肿瘤(LST)内镜下大体形态、腺管开口(Pit)类型、病理形态及内镜下处理等进行研究.方法 记录所有大肠LST的电子肠镜下病变大体形态,所有病变均行超声肠镜检查,观察病变的Pit类型.结果 8例患者共检出9个病灶,病变部位:升结肠2个,横结肠1个,降结肠1个,乙状结肠2个,直肠3个.电子肠镜下病变大体形态:颗粒均一型1个,结节混合型5个,扁平隆起型3个,假凹陷型0个;Pit类型:Ⅱ型2个,ⅢL型4个,Ⅳ型3个.病理形态:管状腺瘤4个,绒毛状管状腺瘤伴中重度异型增生3个,增生性息肉伴腺瘤样改变2个.8个病灶行内镜下分片黏膜切除术(EPMR),1个病灶行外科手术.结论 大肠LST内镜形态具有一定特殊性,处理方法可采用内镜下黏膜切除术(EMR)或EPMR.
