| Guideline for known or suspected button battery ingestion
Make NBM & arrange urgent CXR and AXR
Batteries lodged in oesophagus can cause severe burns in 2 hours
Battery in oesophagus?
Was a magnet
Are related symptoms present?
child < 6yrs?
Re-XRay 4 days post-ingestion (or sooner if symptoms develop). If still in stomach, remove endoscopically (even if asymptomatic)
Immediately remove batteries lodged in oesophagous. Do not delay because patient has eaten.
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:
Discharge home with advice to maintain normal eating and activity.
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.
Urgently remove endoscopically.
Do not induce vomiting or give laxatives as ineffective. Avoid polyethylene glycol solutions as unproven efficacy and may enhance electrolysis.
