    A novel magnet-tipped orogastric tube safely removed metallic foreign bodies from the upper GI tract in pediatric patients. This minimally invasive technique avoided hospitalization, anesthesia, surgery, and radiography, offering a safe alternative for foreign body retrieval.

    Area of Science:

    • Pediatric Gastroenterology
    • Medical Device Innovation
    • Foreign Body Ingestion Management

    Background:

    • Ingestion of metallic foreign bodies is common in children.
    • Traditional removal methods may involve hospitalization, anesthesia, or surgery.
    • Need for safer, less invasive retrieval techniques.

    Purpose of the Study:

    • To evaluate a novel magnet-assisted orogastric tube for metallic foreign body removal.
    • To assess the safety and efficacy of this technique in pediatric patients.
    • To establish an alternative to endoscopic or surgical interventions.

    Main Methods:

    • A magnet was affixed to the distal end of an orogastric tube.
    • The magnet-tipped tube was inserted into the upper gastrointestinal tract.

  • Metallic foreign bodies were retrieved by magnetic attraction.
  • Eight patients (seven children) with ingested metallic foreign bodies were treated.
  • Main Results:

    • Successful retrieval of all metallic foreign bodies in eight patients.
    • No patient required hospitalization, anesthesia, or surgery.
    • No subsequent radiography was needed post-procedure.
    • All patients remained asymptomatic with no complications.
    • No instances of foreign body dislodgement during retrieval.

    Conclusions:

    • Magnet-assisted orogastric tube retrieval is a safe and effective method for upper GI metallic foreign bodies.
    • This technique offers a non-invasive, cost-effective alternative to traditional removal methods.
    • It significantly reduces the need for more invasive procedures in selected cases.
