Eosinophilic esophagitis is a chronic immunoallergic inflammatory disease of the esophagus that represents a major cause of digestive morbidity among the pediatric and young adult populations. Despite the fact that key symptoms in adults include dysphagia and food impaction, many patients lack structural changes in the esophagus to account for their complaints, which suggests the presence of underlying motor disorders and esophageal distensibility impairment. In the last few years the esophageal motility of these patients has been studied using various approaches, most particularly high-resolution manometry, ambulatory manometry, and impedance planimetry. This review focuses on the most relevant findings and scientific evidence regarding esophageal motor disorders in eosinophilic esophagitis.

La esofagitis eosinofílica es una enfermedad inflamatoria crónica del esófago con una base inmunoalérgica que representa una de las principales causas de morbilidad digestiva en la población pediátrica y adulta joven. A pesar de que sus síntomas principales en adultos son la disfagia y las impactaciones alimentarias, gran parte de los pacientes no presentan alteraciones estructurales esofágicas que justifiquen estos síntomas, lo que sugiere la presencia de trastornos motores y alteraciones de la distensibilidad esofágica subyacentes. En los últimos años se ha estudiado la motilidad esofágica de estos pacientes mediante diferentes métodos, entre los que destacan la manometría de alta resolución, la manometría ambulatoria y la planimetría por impedancia. Esta revisión recoge los hallazgos más relevantes y la evidencia científica más destacada acerca de las alteraciones motoras esofágicas en la esofagitis eosinofílica.
