Endoscopic balloon dilation of benign esophageal strictures was performed in 18 dogs & 10 cats w/ a median age of 4yr. Stricture formation was associated w/ a recent anesthetic episode in 18 patients. Regurgitation was the most common clinical sign & was present a median of 4wk before dilation. Most animals had a single stricture; median diameter was 5mm, & median length was 1cm. Esophagitis & mucosal fibrosis were detected in 9 patients each. Dilation was performed w/ progressively increasing diameter balloons, from 6-20mm. After dilation, mucosal hemorrhage was mild to moderate in most patients. Esophageal perforation was the only serious complication & occurred in 1 patient. Postdilation therapy consisted of administration of cimetidine, metoclopramide, sucralfate, & prednisone in most animals. The median # of dilation procedures performed in each animal was 2, w/ a range of 1–5. The median interval between dilations was 13d. Stricture diameter markedly increased w/ subsequent dilations. Median duration of follow-up was 131wk. A successful outcome occurred in 88% of patients, w/ most animals able to eat canned, mashed, or dry food w/o regurgitation. Mucosal fibrosis was associated w/ a better clinical response score, while increasing age was weakly associated w/ fewer dilations. The dilation protocol used in this group of animals was safe & efficacious.
