Abstract

A 1-yr old female lion (Panthera leo) was referred with a 10-mo history of dysphagia for solid food (meat), episodic regurgitation, and poor weight gain. Esophagoscopy confirmed an esophagitis (midesophagus) and a stricture estimated to be of 13 mm diameter. This was subsequently dilated using a 20-mm-diameter balloon for 2 min followed by a 35-mm achalasia balloon for 3 min. The etiology remains undetermined in spite of a thorough history. The animal progressed satisfactorily, reaching 124 kg after 1 yr and has had no further signs. To the authors' knowledge, neither idiopathic esophageal stricture nor dilation using an achalasia balloon has been reported in Panthera spp.
