Summary
Most battery ingestions, especially button batteries, pass through the gastrointestinal tract without intervention. Consumer education is key, particularly for hearing aid batteries, to prevent pediatric battery ingestion hazards.
Area of Science:
- Pediatric Gastroenterology
- Toxicology
- Consumer Product Safety
Background:
- Battery ingestions pose a significant risk, particularly in children.
- Understanding the source and type of ingested batteries is crucial for risk assessment.
Purpose of the Study:
- To analyze the outcomes of battery ingestions.
- To identify risk factors and inform prevention strategies for battery ingestion.
- To evaluate the efficacy of current management strategies.
Main Methods:
- Retrospective analysis of 125 battery ingestion cases over 11 months.
- Categorization of batteries by type (button, cylindrical) and location prior to ingestion.
- Assessment of spontaneous passage, endoscopic retrieval, and medical interventions (ipecac syrup).
Main Results:
- Button batteries were the most common type ingested (119/125).
- Hearing aid batteries were frequently ingested (33.9%), with a notable subset ingested by hearing-impaired children.
- Most batteries (89.9% of button cells, 100% of cylindrical cells) passed spontaneously; endoscopic retrieval and ipecac were largely unsuccessful.
- Symptomatic cases were rare and primarily associated with esophageal lodgment.
Conclusions:
- The majority of battery ingestions are benign and resolve spontaneously.
- Targeted consumer education is needed, focusing on loose batteries and hearing aid batteries.
- Current interventions like endoscopic retrieval and ipecac syrup have limited efficacy for gastrointestinal battery transit.
