Keyword:  放大内镜胃黏膜肠上皮化生胃小凹;
Abstract: 目的应用高清晰放大胃镜观察研究胃黏膜肠上皮化生小凹形态的特点,并与病理学黏液组织化学染色结果进行对照,以提高胃镜下早癌的检出率.方法使用高清晰放大电子胃镜对因上消化道症状就诊的患者进行检查,观察胃黏膜微细形态,并予1%亚甲蓝喷洒,判断肠上皮化生部位,并于各不同形态处取活组织检查.结果入选患者共109例,共观察及活检115个部位,黏膜微细形态可分为6型,其中4型、5型是肠上皮化生的特征性形态,6型是萎缩的特征.结论高清晰放大胃镜下胃黏膜肠上皮化生小凹由正常变为椭圆状甚至绒毛状.依据这些特征可指导活检,避免普通胃镜检查活检的盲目性,提高肠上皮化生的检出率.
