Plain-English summary
This study looked at four dogs that were having trouble with regurgitation, which is when they bring food back up, due to tumors in the lower part of their esophagus. All four dogs showed signs of regurgitation, and three of them also had a condition called megaesophagus, where the esophagus is enlarged and doesn't work properly. Tests confirmed that each dog had a mass in the esophagus that was blocking it, and these masses were found to be cancerous. The responses to treatment varied among the dogs, but one dog was still alive 37 months after being diagnosed.
Abstract
Esophageal neoplasia is an uncommon, but important, consideration for acute and chronic regurgitation and megaesophagus in dogs. The diagnosis can be challenging, and treatment options are often limited. This case series describes four dogs with regurgitation secondary to caudal esophageal masses. All dogs presented with regurgitation, and three of the four dogs had radiographically apparent megaesophagus. In all dogs, ancillary diagnostics revealed the presence of a caudal esophageal mass resulting in esophageal obstruction, and all mass lesions were histopathologically confirmed to be neoplastic. Treatment responses were variable, with one dog still alive 37 mo postdiagnosis at the time of manuscript preparation.
