Esophagitis and esophageal strictures.

Esophagitis and esophageal strictures are relatively uncommon but significant diseases in companion animals. Often, an esophageal disorder is suspected on the animal's medical history and clinical signs. Esophagitis and acquired esophageal strictures are caused by prolonged contact of caustic substances or foreign bodies with the esophageal lining, leading to mucosal injury. In cases of stricture, damage extends into the submucosal and muscular layers. Timely detection and appropriate management of esophagitis and esophageal strictures significantly improve nutritional status, dysphagia, and pain and often return the animal to a normal quality of life. This article reviews the current literature and focuses on the diagnosis and treatment of esophagitis and esophageal strictures caused by fibrosis secondary to esophageal inflammation.
