Dilation of a Proximal Esophageal Stricture by Endoscopically and Radiologically Guided Balloon in a Falabella Foal

Abstract

Esophageal strictures or stenosis are generally triggered by necrosis, as a result of the pressure caused by esophageal impactions that generate ulceration and erosion of the esophageal mucosa, as well as due to lesions caused by the oral administration of corrosive agents, cervical trauma and congenital strictures. Esophageal dilation procedures have been used for the treatment of strictures in humans and small animals but are rarely used in horses, given the number of sessions required for successful treatment and the limited information published on the subject. The objective of this work was to determine the effectiveness of esophageal dilation with an endoscopically and radiologically guided balloon in a Falabella foal with an esophageal stricture caused by an obstruction. The result was successful after five sessions of dilation when the patient tolerated solid food, and no complications were found after six months of observation.
