Hiatal hernia

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

This chapter presents information on etiology/pathophysiology, signalment/history, clinical features, differential diagnosis, diagnostics and therapeutics of hiatal hernia in cats and dogs. The esophageal hiatus is formed by musculature of the medial portion of the lumbar crus of the diaphragm. Esophageal neoplasia, extraluminal masses, vascular ring anomalies, esophageal intussusception, esophageal diverticulum, esophageal foreign body, and megaesophagus are all possible causes of regurgitation. Hiatal hernia is infrequently diagnosed on survey thoracic radiographs alone. Herniation can occasionally be seen during esophagoscopy facilitated by completion of a J-maneuver to directly visualize the lower esophageal sphincter and gastroesophageal juncture. Dogs with mild or infrequent herniation can often be managed as an outpatient unless the animal has severe aspiration pneumonia. Conservative therapy with a fat-restricted diet to facilitate enhanced gastric emptying can be successful in controlling clinical signs in dogs with mild hiatal herniation.
