Experimental Removal of Foreign Bodies by Fiberoptic Bronchoscopy1–3

Abstract

Aspiration of foreign bodies remains a significant clinical problem. Although the majority of objects in the tracheobronchial tree can be removed by rigid bronchoscopy, prompt surgery is required if conventional methods fail. Because the flexible fiberoptic bronchoscope offers greater range and visibility, we investigated its application to the removal of foreign bodies from the airway. A variety of objects were recovered repeatedly from artificial and animal (dog) models using various extraction instruments (forceps, claw, and basket), passed through the channel of the scope. We believe that this study has human application. A skilled fiberoptic bronchoscopist, after a period of training, could use this new technique to augment rigid bronchoscopy in removing foreign bodies from adults and older children. At the present time, the bronchofiberscope is not recommended for pediatric cases because of the small tracheal diameter of infants and young children.
