Esophageal Strictures of the Dog and Cat: Diagnosis and Treatment

Esophageal strictures are a relatively uncommon condition in small animals but they have been well documented. They can be divided in benign and malignant and, based upon their site of origin they are classified as intrinsic (intramural) and extrinsic (extramural). The most common form affecting the dog and cat is the intramural stricture that can be congenital or acquired. At outset, the predominant sign of esophageal stricture is regurgitation shortly after eating. Diagnosis is quite easily established and is based primarily on a detailed clinical history, clinical signs, radiographic examination and endoscopy. Treatment options for esophageal strictures include conservative or surgical procedures. Conservative treatment includes mechanical stricture dilation (bougienage, balloon catheter dilation) and prosthesis placement.
