Esophageal achalasia and secondary megaesophagus in a dog.
A 5-year-old, castrated male, golden retriever was presented with a history of regurgitation. An esophagram revealed normal peristalsis with failure of the lower esophageal sphincter to open, supporting the diagnosis of esophageal achalasia. Prior to surgery, the dog developed megaesophagus. Heller's esophagomyotomy resolved the clinical signs and the esophageal dilation.
