Summary
A retropharyngeal carcinoma diagnosis led to airway procedures. An unexpected tracheo-oesophageal fistula developed during intubation with positive airway pressure, requiring management strategies.
Area of Science:
- Otolaryngology
- Anesthesiology
- Gastroenterology
Background:
- A patient presented with retropharyngeal carcinoma requiring diagnostic and therapeutic airway interventions.
- Pre-procedure evaluations, including barium swallow, did not reveal any signs of a tracheo-oesophageal fistula.
Observation:
- During laryngoscopy and oesophagoscopy under general anesthesia, the patient was intubated.
- Positive airway pressure was applied during mechanical ventilation.
Findings:
- An abnormal communication, indicative of a tracheo-oesophageal fistula, became apparent only after intubation and positive pressure ventilation.
- The fistula was not evident prior to the application of positive airway pressure.
Implications:
- This case highlights a rare complication of airway management in patients with retropharyngeal malignancy.
- It underscores the importance of vigilance for developing tracheo-oesophageal fistulas during positive pressure ventilation.
- Management strategies for such intraoperative complications should be considered.
