This case report describes a 51-year-old man who swallowed an amalgam fragment dislodged during dental treatment performed without a throat screen. The patient was transferred to the emergency department, where the foreign body was confirmed to be in the esophagus following radiographic imaging. Foreign body removal from the esophagus is routinely achieved via esophagogastroduodenoscopy (EGD). However, this incident occurred in September 2020, at the height of the COVID-19 pandemic. Because of the patient's preoperative positive COVID-19 test, the option for EGD retrieval was eliminated per hospital protocol. Instead, a noninvasive approach with serial radiographic monitoring was deemed mandatory to observe the fragment as it passed through the gastrointestinal tract, warranted by the small size of the foreign body and the patient's lack of signs and symptoms of respiratory distress. This case report reinforces the importance of using airway protection during every dental procedure. Furthermore, reevaluation of EGD as the gold standard for treatment of ingested small materials may be warranted.
Initial Anteroposterior Radiograph Containing an Amalgam Fragment
Anteroposterior radiograph obtained upon patient's arrival at the emergency department. The amalgam fragment was located lateral to the midline at the level of C6.
Initial Lateral Radiograph Containing an Amalgam Fragment
Lateral radiograph obtained upon patient's arrival at the emergency department. The amalgam fragment was located within the esophagus at the level of C6.
Anteroposterior Radiograph With an Outline of the Esophagus and a Potential Zenker's Diverticulum
The esophagus and likely position of the Zenker's diverticulum on the anteroposterior radiograph have been outlined in red. This provides an explanation for the lateral positioning of the amalgam fragment seen in Figure 1.
Lateral Radiograph With an Outline of the Esophagus and a Potential Zenker's Diverticulum
The esophagus and likely position of the Zenker's diverticulum on the lateral radiograph have been outlined in red. This outline has been provided to explain the lateral positioning of the amalgam fragment seen in Figure 1.
Anteroposterior Radiograph After Passing the Amalgam Fragment
Anteroposterior radiograph obtained approximately 4 hours after the initial anteroposterior radiograph showing the amalgam fragment no longer present and presumed to have passed into the stomach.
Lateral Radiograph After Passing the Amalgam Fragment
Lateral radiograph obtained approximately 4 hours after the initial lateral radiograph. The amalgam fragment is no longer present and presumed to have passed into the stomach. Extracorporeal radiopacities represent hospital gown buttons (green arrowheads).
