Jejuno-jejunal fistula induced by magnetic necklace ingestion.

We describe the case of a 19-year-old mentally challenged woman who developed jejuno-jejunal fistula following ingestion of a magnetic necklace. This case report demonstrates the necessity of prompt treatment when the ingested intestinal foreign body is suspected to be multiple magnets, even if there are no sharp edges; and even when it seems the object could be evacuated spontaneously. Ingested magnets are capable of attracting each other across the bowel wall, leading to serious intestinal complications such as pressure necrosis, perforation, fistula formation, or intestinal obstruction.
