Abstract

IN RECENT years considerable enthusiasm has been aroused concerning the use of the Alnico magnet for peroral removal of magnetic foreign bodies from air and food passages.1 The usefulness of the magnet has been well demonstrated in other clinics as well as in the Charlotte Eye, Ear and Throat Hospital.2 However, the endoscopic use of forceps is at times a useful adjunct to magnetic foreign body extraction. This is particularly true of large objects which pull away from the magnet at the level of the cricopharyngeal muscle.

In my experience the magnet has been of limited value in the airway. Indeed, I have used it only for removal of a small nail beyond bronchoscopic vision, which required roentgenoscopic aid. Nevertheless, the bronchoscopist has heretofore handled this type of problem very satisfactorily with proper forceps.

When a magnetic foreign body is beyond endoscopic vision in the gastrointestinal tract, the
