Endoscopy in Pediatric Eosinophilic Esophagitis

Abstract

Eosinophilic esophagitis (EoE) is a chronic allergen-mediated clinicopathologic condition that currently requires esophagogastroduodenoscopy with biopsies and histologic evaluation to diagnose and monitor its progress. This state-of-the art review outlines the pathophysiology of EoE, reviews the application of endoscopy as a diagnostic and therapeutic tool, and discusses potential complications related to therapeutic endoscopic interventions. It also introduces recent innovations that can enhance the endoscopist's ability to diagnose and monitor EoE with minimally invasive procedures and perform therapeutic maneuvers more safely and effectively.
