Extraction of airway foreign bodies in adults: experience from 1987-2008.

To determine the incidence and the clinical, radiographic, and endoscopic characteristics of adult patients in our area diagnosed with tracheobronchial foreign bodies (FBs), we have performed a descriptive retrospective study analysing rigid and flexible bronchoscopies practised at our department between 1987 and 2008 in patients older than 14 years. Of the 9781 bronchoscopies performed, 32 involved cases of bronchoaspiration of FBs. The mean age of the patients was 43.81 years (S.D. 21.43); 65.6% were male and 34.4% were female. Acute or recurrent infection was the most frequent clinical presentation. Chest radiographs provided data for diagnosis in 68% of the cases. The most common FB aspirated were inorganic (pins and plastic devices 21.4%, respectively). In conclusion, we can state that in our area tracheobronchial aspiration of FBs by adults is not common. The clinical symptoms are highly variable and the FBs are usually lodged in the right bronchial tree.
