A case of mistaken identity: accidental ingestion of coins causing esophageal impaction in an elderly female.

Coin impaction of the esophagus is infrequently seen in adults, and multiple coin impaction has not been described. The patient was an 85-year-old blind female who presented with 2 days of dysphagia and odynophagia following an attempt to take her medications at bedtime. She reported an esophageal injury from endotracheal intubation during a surgery 6 months earlier. Radiographs showed a radiopaque circular mass in the midesophagus. Endoscopy showed 3 US coins--a nickel, a dime, and a penny--stacked together and impacted on a stricture at 27 cm from the gums. An overtube was planned, but preplacement evaluation showed the lumen was smaller than the coin diameters. An attempt with a retrieval net was unsuccessful. The patient then underwent endotracheal intubation and the coins were removed individually with rat-tooth foreign body forceps. She recovered and underwent successful endoscopic dilation 3 weeks later. She remains asymptomatic since dilation. A brief review of coin impaction and endoscopic management is discussed. Endotracheal intubation for airway protection during endoscopy is recommended for these patients.
