Obstrução esofágica em muar: relato de caso

Abstract

Esophageal obstruction is considered an emergency in equine clinics since high pressure for prolonged periods on the esophageal mucosa provides extensive tissue damage, with subsequent formation of scar tissue, organ stenosis, as well as esophageal perforation. Its etiology is diverse and can be divided into primary and secondary obstructions. Esophageal obstruction presents numerous clinical signs, but dysphagia, regurgitation, neck extension, and sialorrhea appeared more frequently. The aim of the present study is to report the occurrence of esophageal obstruction in muar and to describe its etiology, clinical signs, diagnosis, differential diagnosis, complications, epidemiology and clinical treatment. Female, adult, 300 kg body weight, with history of ptialism, dysphagia and regurgitation after ingestion of mango. Physical examination, nasogastric tube passage, blood count and radiographic examination were performed. After diagnosis, she adopted clinical therapy with venous hydration, alpha 2 agonist tranquilizers, oxytocin, nasoesophageal tube passage and subsequent lavage, broad spectrum antibiotics, food and liquid restriction. The clinical treatment was effective to resolve the esophageal obstruction. The muar was discharged 8 days after the start of treatment.
