[Physiopathologic features of gastroesophageal reflux in children]

Abstract

Gastroesophageal reflux in children is a frequent problem of pediatrics. According to a literature review, it was showed and discussed some pathophysiological factors related to the genesis of gastroesophageal reflux in infancy: which facilitates the reflux episodes more frequently, interferes in esophageal clearance, makes the reflux more aggressive or which facilitates upper airway aspiration. Some questions are pointed: gastroesophageal reflux in children is different from the adult; the genesis is multiple and gastroesophageal reflux is part of a gastrointestinal motility disorder as a whole.
