Oesophageal Fistula



Typical Signalment

  • Cairn Terrier for congenital fistula

Description

An abnormal connection between the oesophageal lumen and surrounding structures most commonly involving the lungs or other respiratory structures. Can be congenital (rare) or acquired. With congenital fistulae, the animals usually have oesophageal foreign bodies. Acquired oesophageal fistulae usually result from foreign bodies (usually bones and grass seeds) leading to lumen perforation and inflammation spreading into adjacent tissues. Secondary complications include:

  • localized pneumonia
  • pleuritis
  • pulmonary abscessation
