    Abstract:
    OBJECTIVE: Tracheobronchial foreign bodies (FBs) are frequently present in adults. This study reports our experience with the managements of FB and FB-related complications using flexible bronchoscopy. METHODS: We retrospectively reviewed the adult patients with FBs treated between 2001 and 2011 in China. The demographic and endoscopic data were collected and analyzed. RESULTS: A total of 200 adult patients (136 men and 64 women) with an average age of 51 years were analyzed. The most common FBs included bones (51.0%), nut shells (15.0%), food boluses (7.0%), plastic toys or pen caps (6.5%). After FB aspiration occurred, only 11.0% were diagnosed within three days, while more than half of the patients (58.0%) delayed the diagnosis by more than one month. The incidence of FB-related complications was 79.5%, including granulation formation (76.5%), obstructive pneumonia (22.0%), hemorrhage (14.5%), atelectasis (10.0%) and endobronchial stenotic scarring (8.0%). In 96.5% of the patients, the FBs were successfully removed under flexible bronchoscopy. A total of 53 out of the 153 patients with granulation (34.6%) were managed by argon plasma coagulation (APC) or cryotherapy; two out of the sixteen patients with endobronchial stenotic scars were treated by balloon dilation under flexible bronchoscopy. CONCLUSION: A high incidence of FB-related complications occurs, likely as a result of the long delay between aspiration and diagnosis, a proportion of which require endoscopic intervention. The removal of FBs under flexible bronchoscopy has a high success rate and therefore should be recommended for adults.
