Defining the stage guides procedures and treatment, given that in mild forms (stage I) the treatment and follow-up can be performed in the ambulatory environment while moderate to severe cases require hospitalization so that intravenous treatment and treatment outcome monitoring can be started. Supportive treatment, re- moval of intrauterine device (IUD), sexual abstinence and rest are also indicated, as well as counseling on the implications of the disease and partner approach.

RESUMO A doença inflamatória pélvica (DIP) é um processo inflamatório de natureza infecciosa que pode atingir estruturas e órgãos do trato genital superior. Devido à sua importância epidemiológica e de suas graves complicações, este artigo atualiza e propõe uma abord- agem sistemática da DIP. Os principais agentes etiológicos são a Neisseria gonorrhoeae, Chlamydia trachomatis e outros agentes etiológicos de uretrites, cervicites, vulvovaginites e vaginoses, em geral, polimicrobiana, o que é a base de sua terapêutica. A mulher deve ser investigada para DIP quando apresenta, especialmente, desconforto abdominal, dor lombar, dispareunia e nódoas ou manchas ao exame ginecológico, previamente a pro- cedimentos transcervicais.
