Pathogenesis

Pathophysiology

  • Persistent regurgitation/lack of oral intake → dehydration → electrolyte imbalance.
  • Pressure necrosis may lead to:
    • Penetration of the cervical esophagus → contamination and cellulitis of the cervical tissue.
    • Thoracic perforation → catastrophic mediastinitis and pleurisy.

Timecourse

  • Hours to days.
