To report an extremely rare case of congenital esophageal stenosis in a puppy.
Materials & Methods
A two-month-old, male, miniature pincher dog was presented with the history of an acute onset of regurgitation at the time of weaning to solid foods. Congenital esophageal stenosis was identified from persistent right aortic arch (PRAA) by esophagoscopy. Bougienage was performed one time by a series of graded diameter of Salvary Gillard Dilator. The pup was intravenously administered with dexamethasone (1 mg/kg) an hour prior to dilatation and had prednisolone (1 mg/kg) orally for two weeks after the procedure.
Upon esophagoscopic examination, the esophageal mucosa at the stenosis site was intraluminal stenosis with normal mucosa and the stenosis opening located centrally of the lumen whereas a dog affected with PRAA showed extraluminal esophageal stenosis. The etiology has been precluded from reflux esophagitis or mucosal trauma caused by foreign impaction or corrosive chemicals/irritating drugs administration because of no evidence of reflux esophagitis and no history indicated. The dog has been able to have rice mixed with small pieces of chicken or pork and doing well upon fourteen-month follow up.
Bugienage with pre-and post-operative steroids therapy was a good technique in treatment the puppy affected with congenital esophageal stenosis.
