Material and Method

We present 4 clinical cases with magnet extraction strategies treated at our center between 2023-2024.

Results

A 10-year-old boy inserted 40 magnetic balls into his urethra, asymptomatic with preserved diuresis. X-ray revealed magnets in the bladder, excluding spontaneous expulsion. Cystoscopy was performed and progressive extraction using a magnetic catheter under fluoroscopic guidance.

A 9-year-old asymptomatic girl admitted after ingesting 8 spherical magnets. They were in the right iliac fossa without progression over 24 hours. Appendectomy was performed using a Gloveport, externalizing the cecum through the umbilical wound and removing the magnets through the appendiceal stump.

A 6-year-old boy presented with abdominal pain and vomiting due to cecal and intestinal loop perforations caused by the ingestion of a metallic chain and spherical magnets. Laparoscopy was performed by Gloveport, with externalization through the umbilicus, followed by intestinal resection and primary anastomosis.

A 7-year-old boy underwent surgery for clinical and radiological findings of intestinal obstruction following the ingestion of multiple magnets 10 days earlier. Laparoscopy was performed using a Gloveport, revealing multiple intestinal fistulas that were sectioned and closed with a mechanical stapler. One of them was used to extract the magnets under fluoroscopic guidance.

Conclusions

The described techniques stand out as safe minimally invasive strategies for managing injuries caused by magnets in the pediatric population.
