A three-year-old female spayed Golden retriever presented with a two-week history of regurgitation due to oesophageal stricture formation. Further diagnostics revealed two oesophageal strictures located at the thoracic inlet and caudal to the heart base, respectively. Endoscopic balloon dilation was performed four times at weekly intervals but recurrence of stricture formation was noted clinically within a few days after each procedure and was confirmed endoscopically. Finally, intralesional injection of triamcinolone acetonide was performed in combination with the fifth balloon dilation procedure. The dog recovered clinically and a final endoscopic examination performed 16 weeks after the injection did not reveal any evidence of oesophageal strictures.
