Abstract
For removal of radiopaque foreign body in the air way, the authors has usually used the ventilation bronchoscscope with an aid of fluoroscope and image amplifier. However, success of removal of radiolucent foreign body depends much on surgeons skill, and in case of peanut in the air way the highly skillful technique is required.
Recently, the authors attempted to change a radiolucent peanut to a radiopaque and to remove the peanut under fluoroscope.
A peanut in the air way visualized through a bronchoscope and tantalum powder was sprayed as to delineate the surface of the peanut which became radiopaque and well visualized in an image amplifier under fluoroscope. Every piece of crached peanut could be removed completely and safely.
