Pathogenesis

Etiology

  • Acquired by hunting and playing behavior.

Pathophysiology

  • Persistent regurgitation   →   dehydration   →   electrolyte loss.
  • Penetration of the cervical esophagus   →   contamination and cellulitis of the cervical tissue.
  • Thoracic perforation   →   catastrophic mediastinitis and pleurisy.
  • Larger foreign bodies   →   rapid deterioration because of the greater likelihood of pressure necrosis and perforation.
