**4. Endoscopic treatment for Eosinophilic Esophagitis (EoE)**

Since the first descriptions of EoE appeared in the literature, the disease has been associated with alterations in the caliber of the esophagus, which specialists have sought to correct by means of endoscopic dilation. In this sense, endoscopic therapy has always been recognized as one of the main treatment modalities in EoE patients, together with systemic and topical steroids and changes in diet.

The efficacy of endoscopic treatment in EoE patients is clear in emergency situations, in which it is needed to resolve food impactions that block the esophageal lumen, and also in scheduled explorations of patients with esophageal symptoms, especially if these are accompanied by a reduced esophageal caliber. The characteristic fragility of the esophageal wall in these patients initially led several authors to consider endoscopic techniques to be a risky treatment option (Lucendo, 2007). We will discuss this assertion in greater depth after reviewing new evidence from the latest studies.
