Postanesthetic esophageal dysfunction in dogs can lead to serious complications like esophageal stricture and aspiration pneumonia. This condition is debilitating, costly, and can occur even with preventative measures.

Area of Science:

  • Veterinary Medicine
  • Anesthesiology
  • Gastroenterology

Background:

  • Postanesthetic esophageal dysfunction is a recognized complication in dogs.
  • Esophageal stricture is a common sequela, often leading to significant clinical signs.

Purpose of the Study:

  • To investigate the incidence, clinical manifestations, and outcomes of postanesthetic esophageal dysfunction in dogs.
  • To highlight diagnostic delays and the impact of this condition on canine patients.

Main Methods:

  • Retrospective case series of thirteen dogs diagnosed with postanesthetic esophageal dysfunction.
  • Review of clinical records, anesthetic events, and diagnostic findings.

Main Results:

  • Ten out of thirteen dogs developed esophageal stricture.

  • Common clinical signs included vomiting, regurgitation, and weight loss; four dogs developed aspiration pneumonia.
  • A 23% mortality rate was observed, with diagnostic delays up to 76 days.

    • Conclusions:

    • Postanesthetic esophageal dysfunction is a severe condition in dogs, frequently resulting in esophageal stricture and potentially fatal complications.
    • Early diagnosis and intervention are crucial to improve outcomes and reduce mortality associated with this condition.
