Summary
Hypoxemia during endoscopy can stem from various causes, including rare instances of pneumomediastinum and tension pneumothorax without gastrointestinal perforation. Prompt recognition and intervention are crucial for patient recovery.
Area of Science:
- Medicine
- Gastroenterology
- Pulmonology
Background:
- Hypoxemia is a frequent complication during endoscopic procedures.
- Causes range from oversedation to severe events like pneumothorax secondary to gastrointestinal perforation.
- Pneumothorax without perforation during endoscopy remains unreported.
Observation:
- A patient developed severe hypoxemia and hemodynamic instability during diagnostic upper endoscopy.
- The complication arose from pneumomediastinum and tension pneumothorax.
- No evidence of gastrointestinal perforation was found.
Findings:
- This case highlights pneumomediastinum and tension pneumothorax as potential causes of hypoxemia during endoscopy, independent of gastrointestinal perforation.
- The patient's condition rapidly improved following endotracheal intubation and bilateral chest tube placement.
Implications:
- This report expands the differential diagnosis for hypoxemia during endoscopic procedures.
- It underscores the importance of early recognition and prompt, targeted management for favorable outcomes.
