Endoscopic retrieval of magnetic foreign body ingestions with a nasal bridle: description of a novel technique (with video)

Abstract

Background and aims: Accidental and intentional foreign body ingestions are common and frequently require endoscopic intervention. Sharp metallic objects pose a risk of perforation to the entire GI tract and are often difficult to visualize among food and other matter in the stomach.

Methods: Three patients with histories of multiple ingestions are considered. Metallic foreign bodies can be easily removed using a nasal bridle. A snare and magnetic catheter are used as endoscopic tools to extract various metallic items.

Results: The bridle technique was used in 68 endoscopies in 3 patients who presented numerous times for foreign body ingestions. The technique was successful in 66 of the 68 procedures, with no adverse events.

Conclusions: The bridle technique is an easy and effective way to remove metallic foreign bodies and has many advantages over traditional, mechanical modes of foreign body retrieval.
