Congenital oesophageal stricture in an Arabian filly treated by balloon dilation

Congenital oesophageal stricture was diagnosed via endoscopy in a 3‐day‐old Arabian filly suffering from nasal milk regurgitation. Vascular ring anomaly or other extramural, intramural or intraluminal causes were not identified on radiographs or on a computed tomography scan; thus a functional abnormality was suspected. The filly was treated with antibiotics for aspiration pneumonia and was fed milk through an indwelling nasoesophageal tube. Two sessions of balloon bougienage at the stenotic site, under sedation, resulted in marked clinical improvement and thereafter the filly was gradually reintroduced to suckling from the mare. The filly was discharged from the hospital after 17 days and on follow‐up there were no reports of food regurgitation even after the introduction of solid food. The filly was still doing well in the latest follow‐up at age 11 months.
