Flexible Bronchoscopy Combined with Rigid Bronchoscopy for Treatment of Scarring in the Bronchus Caused by a Foreign Body

摘要

Foreign body (FB) aspiration into the tracheobronchial tree is an emergency in the pediatric department, particularly in children aged 3?years. FB granulation tissue is commonly found in children with FB aspiration. However, scarring in the bronchus caused by a FB is rare. We herein report a case involving aspiration of a plastic whistle toy with scarring in the bronchus. The scar tissue was successfully removed by interventional bronchoscopy combined with a flexible electrosurgery probe and carbon dioxide cryotherapy.
