  • Title: Persistent regurgitation in four dogs with caudal esophageal neoplasia.
    Author: Arnell K, Hill S, Hart J, Richter K.
    Journal: J Am Anim Hosp Assoc; 2013; 49(1):58-63. PubMed ID: 23148135.
    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.
