Objetivo<\/h2>\n\n\n\n


A gastrite atr\u00f3fica \u00e9 um achado frequente de exames endosc\u00f3picos, sendo um dos fatores de risco para o desenvolvimento de c\u00e2ncer g\u00e1strico.  Para identificar e estratificar grupos de risco foi criada uma classifica\u00e7\u00e3o denominada OLGA (Operative<\/em> Link of Gastritis Assesment<\/em>)<\/a>, baseada na localiza\u00e7\u00e3o das bi\u00f3psias e achados histol\u00f3gicos avaliando de forma objetiva o grau de atrofia.  A classifica\u00e7\u00e3o \u00e9 reprodut\u00edvel, de f\u00e1cil execu\u00e7\u00e3o, permitindo selecionar o grupo de pacientes de maior risco que devem ter seguimento mais r\u00edgido, mantendo a custo-efetividade do rastreamento. <\/p>\n\n\n\n

    A atrofia (com ou sem metaplasia) \u00e9 graduada em cada topografia (antro e corpo) em escala de 0 a 3 (ausente, leve, moderada, grave).<\/p>\n\n\n\n
