Objective:

To analyze the clinical characteristics, imaging findings, and risk factors for complications of gastrointestinal foreign bodies in children, and to provide evidence for clinical diagnosis and treatment.

Approach:

Key Findings:

• 57.7% of patients were male, with a median age of 3 years.
• Magnetic beads were the most common foreign body (54.9%), followed by coins (12.7%) and water-absorbing beads (8.5%).
• The small intestine was the main impaction site (41.5%).
• Complications occurred in 70.4% of patients, with perforation in 45.1% and obstruction in 36.6%.
• Independent risk factors for complications included sharp/corrosive foreign bodies, retention time >24 h, upper gastrointestinal location, and symptomatic presentation.
• Ultrasound effectively detected radiolucent foreign bodies, while plain radiography did not.

Interpretation:

Magnetic beads are identified as high-risk gastrointestinal foreign bodies in children, with specific risk factors indicating the need for early intervention.

Limitations:

• Single-center study may limit generalizability.
• Retrospective design may introduce selection bias.

Conclusion:

Magnetic beads are the most common and high-risk gastrointestinal foreign bodies in children. Ultrasound is valuable for detecting radiolucent objects. Early intervention is warranted for specific risk factors.
