Developing a management protocol for magnet ingestion in pediatric patients

Area of Science:

• Pediatric Gastroenterology
• Pediatric Surgery
• Medical Device Safety

Background:

• Ingestible products with magnetic components are increasingly common, leading to a rise in pediatric magnet ingestions.
• Multiple magnet ingestions pose significant risks, often necessitating surgical intervention due to potential complications.

Purpose of the Study:

• To develop a management protocol for children who have ingested multiple magnets.
• To identify predictors of complications and guide timely interventions.

Main Methods:

• Retrospective review of children treated for magnet ingestion between 2000 and 2024.
• Analysis of symptoms, radiographic findings, and interventions performed.

Main Results:

• 143 children ingested magnets; 57% involved multiple magnets, often unwitnessed.
• Conservative management failed in 41% of multiple magnet ingestions, requiring surgery, primarily due to lack of radiographic progression.
• Surgical intervention was prompted by lack of magnet progression within 24 hours, preventing complications like bowel perforation.

Conclusions:

• Lack of foreign body progression on imaging within 24 hours in conservatively managed pediatric multiple magnet ingestions warrants surgical intervention.
• The study proposes an algorithm to guide prompt surgical intervention when conservative management fails.
