AbstractIngestion of foreign bodies is common in gastroenterology practice. Most of them are spontaneously passed through gastrointestinal tract. However, ingestion of multiple magnets can cause serious complications, because magnets attract each other and they hold the gastrointestinal wall. Here, we describe a patient who ingested multiple magnets that attracted each other between distal esophagus, and a part of them was impacted into the esophageal wall. In general, impacted magnetic foreign bodies should be removed by surgical intervention because of a high perforation risk. But, in this case, we used an insulated-tip knife for endoscopic submucosal dissection technique to make an incision to expose the impacted magnetic foreign bodies, and removed them successfully without surgery. With this report, we hope to encourage gastroenterologists to consider this new technique as one of procedures for difficult cases, including impacted foreign bodies.
