Management of Ingested Coin in Asymptomatic Children

Initial Radiographic Assessment

Obtain two-view abdominal radiographs immediately to determine the current location of the coin, as coins that remain in the esophagus for more than 24 hours require endoscopic removal even in asymptomatic patients 1
The American Academy of Pediatrics recommends that the coin's orientation on radiograph helps determine location: coins in the esophagus typically appear en face (circular) on anteroposterior view and edge-on (linear) on lateral view, while coins in the trachea show the opposite pattern 1

Urgent endoscopic removal is indicated for any coin that has been in the esophagus for more than 24 hours, regardless of symptoms, due to risk of pressure necrosis, perforation, and fistula formation 1, 2

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 will 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

Immediate endoscopy is required if the child develops any symptoms including dysphagia, drooling, chest pain, abdominal pain, vomiting, or respiratory symptoms, as these suggest complications 1, 2
Surgical consultation is needed if there are signs of perforation (fever, severe pain, peritoneal signs) or if the coin fails to progress despite appropriate observation period 2
