Case Reports

Esophageal pH monitoring via wireless probes is used to evaluate chest pain and atypical symptoms and diagnose gastroesophageal reflux. These probes are commonly placed during esophagogastroduodenoscopy performed by gastroenterologists in an ambulatory anesthesia setting. Dislodgment and aspiration of these probes can cause morbidity, require surgical removal, and involve the anesthesia provider in prolonged emergency care. We present a case of a probe dislodgment where aspiration was avoided and describe how retrieval of this device is different from typical hypopharyngeal foreign body removal.
