Management of a 4-Year-Old Who Swallowed a Nickel
Obtain immediate two-view radiographs (anteroposterior and lateral) to determine the coin's current location, as this dictates all subsequent management decisions. 1
Immediate Radiographic Assessment
- Get AP and lateral abdominal/chest radiographs immediately to localize the nickel 1, 2
- The coin's orientation on radiograph reveals its location: coins in the esophagus appear circular (en face) on AP view and linear (edge-on) on lateral view, while coins in the trachea show the opposite pattern 1
- The C4-C7 vertebral level corresponds to the upper esophageal sphincter where coins frequently lodge in children 2
Management Based on Coin Location
If the Nickel is in the Esophagus
Urgent endoscopic removal is required if the coin has been in the esophagus for more than 24 hours, even in asymptomatic children, due to risk of pressure necrosis, perforation, and fistula formation. 1, 2
- If complete esophageal obstruction is present (inability to swallow saliva, drooling, respiratory distress): perform emergent flexible endoscopy within 2-6 hours 2
- If no complete obstruction: perform urgent flexible endoscopy within 24 hours 2
- Prolonged esophageal retention can lead to pressure necrosis, perforation, and mediastinitis 2
If the Nickel is in the Stomach or Beyond
Continue expectant management with observation if the coin has passed beyond the pylorus and the child remains asymptomatic. 1
- Most coins that reach the stomach pass spontaneously through the gastrointestinal tract within 2-4 weeks without intervention 1
- Obtain repeat radiograph in 3-4 weeks if the coin has not been visualized in the stool to confirm passage 1
- No immediate intervention is needed for asymptomatic children with coins in the stomach or intestines 1
Red Flags Requiring Immediate Intervention
Immediate endoscopy is mandatory if the child develops any of the following symptoms, as these suggest complications: 1
- Dysphagia or drooling
- Chest pain or abdominal pain
- Vomiting
- Respiratory symptoms (stridor, cough, wheezing)
Surgical consultation is needed if there are signs of perforation (fever, severe abdominal pain, peritoneal signs) or if the coin fails to progress despite appropriate observation 1
Critical Pitfalls to Avoid
- Do not delay imaging in a child with witnessed or suspected coin ingestion—the location determines urgency of intervention 1, 2
- Do not assume the coin will pass if it's in the esophagus—esophageal coins require active removal, not observation 1, 2
- Do not dismiss symptoms—any new symptoms after coin ingestion warrant immediate re-evaluation regardless of initial radiograph findings 1
- Children aged 3 years or younger are at highest risk for choking and complications from foreign body ingestion 2
