icanis
Contributor(s):

Introduction

  • Resolution of esophageal stricture by means of a balloon dilation technique.
  • Balloon inflated within esophageal lumen at site of stricture to stretch muscle fibers and break down fibrous tissue.

Uses

Advantages

  • Most animals (50-70%) show improvement following the technique. The magnitude of the improvement depends on the underlying pathology.
  • Balloon catheter dilation is the treatment of choice; there is less risk of perforation than with bougienage and fewer dilations are required to resolve symptoms.

Disadvantages

  • Repeated dilations may be required, usually at 1-3 week intervals, in severe cases.
  • General anesthesia General anesthesia: overview is always required.
  • Ideally, fluoroscopic guidance should be employed during treatment. The availability of this modality is, however, limited.
  • An endoscope is required.
  • Potential risk of esophageal perforation.
