Management of Battery in the Stomach
For a button battery lodged in the stomach, observe asymptomatic patients with repeat imaging in 7-14 days to confirm passage, but perform urgent endoscopic removal (within 2-6 hours) if the patient develops any symptoms or if the battery remains in the stomach beyond 48 hours. 1, 2
Immediate Assessment and Risk Stratification
- Obtain plain radiographs immediately to confirm the battery location and rule out esophageal impaction, which would require emergent intervention. 1
- Determine the time since ingestion—this is critical for deciding management strategy. 2
- Assess for symptoms including vomiting, abdominal pain, hematemesis, drooling, or refusal to eat, as these indicate need for urgent removal. 1, 3
Management Algorithm for Gastric Batteries
For Asymptomatic Patients with Early Diagnosis (≤12 hours)
- Monitor conservatively with repeat abdominal X-ray in 7-14 days if the battery has not already passed in stool. 2
- This approach is safe and avoids unnecessary intervention, as most gastric batteries will pass spontaneously without complications. 4
- Do not routinely admit asymptomatic patients for observation or perform serial imaging. 4
For Symptomatic Patients
- Perform urgent flexible endoscopy within 2-6 hours regardless of time since ingestion. 1
- Symptoms such as vomiting indicate potential mucosal injury—gastric erosions can develop rapidly even within 2 hours of ingestion. 5
- Use appropriate retrieval techniques including grasping forceps, baskets, or snares during endoscopy. 6
For Batteries Remaining in Stomach >48 Hours
- Remove the battery endoscopically or surgically if it remains fixed in the stomach beyond 48 hours, as prolonged contact increases risk of perforation and severe mucosal injury. 7
For Delayed Diagnosis (>12 hours after ingestion)
- Consider endoscopy to screen for gastric damage even if the battery has passed beyond the stomach, particularly in children. 2
- Evaluate for potential complications including perforation or significant mucosal injury. 2
Critical Contraindications
- Do not induce vomiting or administer activated charcoal. 1
- Do not administer water or milk unless specifically advised by poison control. 1
- Do not delay necessary intervention with prolonged observation periods if symptoms develop. 6
Special Considerations
- Honey (in children >1 year) or sucralfate may be administered if ingestion is <12 hours old and endoscopic removal will be delayed, but this should not delay definitive management. 1
- If complications such as perforation are suspected, obtain CT imaging before attempting removal. 2
- Gastroenterology consultation is the primary specialty for endoscopic removal via flexible endoscopy. 6
Key Clinical Pitfall
The most dangerous error is assuming all gastric batteries are benign—while many pass spontaneously, rapid mucosal injury can occur even in asymptomatic patients, and symptoms may develop suddenly requiring urgent intervention. 5, 3
