ABSTRACT

ABSTRACT Gastroesophageal reflux disease (GERD) is the most common disease of the upper gastrointestinal tract in the Western world. GERD pathophysiology is multifactorial. Different mechanisms may contribute to GERD including an increase in the transdiaphragmatic pressure gradient (TPG). The pathophysiology of GERD linked to TPG is not entirely understood. This review shows that TPG is an important contributor to GERD even when an intact esophagogastric barrier is present in the setting of obesity and pulmonary diseases.


RESUMO A doença do refluxo gastroesofágico (DRGE) é a enfermidade mais comum do trato digestivo alto no mundo ocidental. A fisiopatologia da DRGE é multifatorial. Diferentes mecanismos podem contribuir para um aumento do gradiente pressórico transdiafragmático (GPT). A fisiopatologia da DRGE associada ao GPT não é totalmente compreendida. Esta revisão enfoca que o GPT é um importante contribuinte para DRGE mesmo na presença de uma barreira gastroesofágica intacta como na obesidade e doenças pulmonares crônicas.
