Management of foreign bodies in the aerodigestive tract.

Foreign body (FB) aspiration and ingestion are frequently encountered by emergent otolaryngology services. The authors describe their experience in the management of FB cases in the aerodigestive tract. We carry a retrospective study about 626 patients who came or were referred to our department between 1996 and 2007 with a history or suspicion of a FB in the aerodigestive tract (except nasal and oropharyngeal FB). All of them have undergone rigid endoscopy under general anaesthesia. Children younger than 10 years were the most involved (36.9%) followed by patients between 71 and 80 years old (11.3%). The FB were visible on clinical examination in 39 cases. Chest and neck X-ray, showed radio-opaque FB in 302 cases (48.7%). A total of 626 rigid endoscopies were performed. FB were encountered in 549 patients (87.7%). The most involved sites were the oesophagus (51.9%) followed by the tracheobronchial tree (33.9%) and the hypopharynx (13.5%). Bones (22%) and coins (20.1%) were the most frequently encountered FB. Successful removal was achieved in 521 cases (94.9% of the FB found). The complication rate after rigid endoscopy was 1.3%. FB in the aerodigestive tract are frequent and may lead to severe complications. Removal through the rigid endoscope still has its place as the most reliable method. Prevention and public education for this serious problem should be considered.
