child < 6yrs?
Re-XRay 4 days post-ingestion (or sooner if symptoms develop). If still in stomach, remove endoscopically (even if asymptomatic)
Endoscopic removal is recommended as allows direct visualisation of tissue injury:
Note extent, depth and location of tissue damage, and position of battery and direction of negative pole. Remember the “3 N” rule:
Negative-Narrow-Necrotic. The negative battery pole, identified as the narrowest side on lateral X-Ray caused the most severe necrotic injury.
Refer to full guideline for management post-removal.
If in stomach remove endoscopically even if symptoms appear minor. If battery is beyond reach of endoscope, surgical removal is reserved for unusual patients with:
Confirm battery passage by inspection of stools.
Consider re-XRay to confirm passage if passage not observed 10-14 days, or parental concern.
If symptoms develop later, promptly re-evaluate
Do not wait for symptoms.
Do not induce vomiting or give laxatives as ineffective. Avoid polyethylene glycol solutions as unproven efficacy and may enhance electrolysis.
