This technique requires very little patient cooperation.An immobile battery, for example, in the esophagus, nose, or ear, requires emergent removal to prevent perforation at the site of impaction and subsequent infection.Two or more rare-earth magnets in the gastrointestinal tract or on both sides of the nasal septum require emergent removal because of the potential of erosion and perforation of the tissue between the two adherent magnets.
