Show Hint
Foreign body rules: Coin in Esophagus $\rightarrow$ Remove endoscopically within 24 hours. Coin in Stomach (asymptomatic) $\rightarrow$ Observe for up to 2--4 weeks. Button battery in esophagus $\rightarrow$ Emergency removal ($<2$ hours)!

- Observe and wait for the coin to pass through the stool
- Remove immediately via endoscopy
- Urgent surgical removal
- Start laxatives

The Correct Option is A
Solution and Explanation
Concept:
Ingested foreign bodies in children are a common pediatric emergency.
Management algorithms depend strictly on the anatomical location of the foreign object, its characteristics (e.g., blunt coin vs. button battery vs. sharp object vs. multiple magnets), and the presence or absence of symptoms.
Explanation:
• A smooth, blunt foreign body such as a standard coin that has successfully negotiated the lower esophageal sphincter into the stomach will pass through the remainder of the gastrointestinal tract uneventfully in $>95\%$ of cases.
• For an asymptomatic child with a coin confirmed in the stomach on radiograph, the gold-standard recommendation is expectant management (observation) on a normal diet while monitoring stools for passage.
• Endoscopic removal is only indicated if the coin remains lodged in the stomach for longer than $2$--$4$ weeks without progressing, or if the child develops symptoms such as abdominal pain, vomiting, or gastrointestinal bleeding.
• Urgent endoscopic intervention is reserved for coins lodged in the esophagus, button batteries in the esophagus/stomach, sharp-pointed objects, or multiple magnets.
• Cathartics, emetics, and laxatives are completely unnecessary, unproven, and potentially harmful in pediatric foreign body ingestion.
Final Answer:
The correct and safe next step for an asymptomatic child with a coin in the stomach is observation to allow spontaneous passage through the gastrointestinal tract.
