Estenose esofágica em duas cadelas após ovário-histerectomia: Relato de caso

Abstract

Benign esophageal stricture is a rare affection in small animals, usually secondary to ulcerative esophagitis. Gastroesophageal reflux, frequent during anesthetic procedures, is the main cause of severe esophagitis with consequent formation of esophageal cicatrix. The objective of this work is to describe two cases of esophageal stricture occurring after ovariohysterectomy, highlighting the diagnostic procedures performed. In both cases, the combination of the suggestive clinical signs and findings from an esophagram and an esophagoscopy were determinants. In the first case, due to the advanced stage of the clinical signs, the patient died before direct interventions on the stenosis region were performed. But in the second case, the gastrostomy procedures for better feed management associated with esophageal dilatation by esophagoscopy and therapy with antacids resulted in clinical improvement.
