Management of Coin Ingestion in a 10-Year-Old Child
All children who have swallowed a coin require plain chest and neck radiography to determine if the coin is lodged in the esophagus, regardless of whether they have symptoms 1, 2.
Initial Evaluation
Radiographic Assessment
- Obtain biplanar (AP and lateral) chest and neck radiographs to identify the presence, location, and orientation of the coin 3
- Plain abdominal films are unnecessary if the coin is not visualized in the chest/neck, as coins below the diaphragm pass spontaneously 4
- Up to 30% of children with esophageal coins are completely asymptomatic, making imaging essential even without symptoms 2
Clinical Assessment
Look specifically for:
- Dysphagia or inability to swallow saliva
- Drooling (highly predictive of esophageal impaction)
- Choking at time of ingestion
- Vomiting or chest pain
- Odynophagia or neck tenderness 3, 1
Critical caveat: The absence of symptoms does NOT exclude esophageal impaction—approximately 14-30% of children with esophageal coins have no symptoms at presentation 1, 2.
Management Algorithm Based on Coin Location
If Coin is in the Esophagus:
For symptomatic children or complete obstruction:
- Urgent flexible endoscopy within 24 hours (preferably sooner if complete obstruction) 3
- Coins are not considered emergent like batteries or sharp objects, which require removal within 2-6 hours 3
For asymptomatic children with esophageal coins:
- A period of observation for 8-16 hours is reasonable, as 23-30% will pass spontaneously into the stomach 5, 6
- Spontaneous passage is more likely in:
- Older children (this 10-year-old is in a favorable age group)
- Males
- Coins located in the distal third of the esophagus 5
- For middle/lower esophageal coins specifically, up to 65% may pass spontaneously within 6-12 hours 6
- Repeat radiograph after the observation period to confirm passage to stomach 5
If the coin remains in the esophagus after observation or if symptoms develop:
- Proceed with flexible endoscopy for removal 3
- Success rate of endoscopic removal approaches 90-100% 7
If Coin is Below the Diaphragm (Stomach or Intestines):
- Conservative management with observation 8
- Coins that have passed the duodenojejunal flexure will pass spontaneously in the vast majority of cases (>95%) 8
- No repeat imaging needed unless symptoms develop
- Parental reassurance and counseling about prevention 8
Key Clinical Pitfalls
Do not skip radiography in asymptomatic children—17-30% of asymptomatic children have esophageal coins 1, 2
Avoid contrast studies—they risk aspiration with complete obstruction and impair endoscopic visualization 3
Do not perform serial abdominal radiographs for coins that have passed into the stomach—this exposes children to unnecessary radiation 4
Consider underlying esophageal pathology—up to 25% of children with coin impaction have underlying disorders like eosinophilic esophagitis, strictures, or webs 3, 7
Endoscopic Technique When Required
- Flexible endoscopy is first-line 3
- General anesthesia with airway protection is typically used 3
- "Push technique" (gently advancing coin into stomach) has 90% success rate with low complications 3
- Retrieval with forceps, baskets, or snares if push technique fails 3
The practical approach for this 10-year-old: Obtain chest/neck X-ray immediately. If the coin is esophageal and the child is asymptomatic, observation for 8-16 hours with repeat imaging is reasonable given the high spontaneous passage rate in this age group. If symptomatic or the coin persists, proceed with endoscopic removal within 24 hours.
