Abstract
Background:
Foreign-body aspiration is common in children aged 6 months to 3 years. However, with the aging population and increasing prevalence of disabilities such as hemiparesis and neuromuscular diseases in adults, an increased incidence of aspiration is expected.

Methods:
This was a multicenter retrospective, observational study in four major referral hospitals in Daegu, South Korea, between 2000 and 2019. We included patients aged over 18 years who were evaluated for tracheobronchial foreign-body aspiration by flexible bronchoscopy. Comorbidities, type and location of foreign body, and radiologic findings were recorded.

Results:
Of 138 patients who underwent flexible bronchoscopy for tracheobronchial foreign body aspiration, 91 (65.9%) were men; the mean age was 66.3 (range: 29–87) years. A history of definite choking was present in 60 (43.5%) patients. The most common site of the foreign body was the right bronchus intermedius (27.5%). The most common type of aspirated foreign body was teeth (37.7%), followed by chicken bone (15.2%), nuts (14.5%) and fish bone (9.4%). Iatrogenic events accounted for 37.0% of the cases of aspiration, and the foreign body was successfully removed by flexible bronchoscopy in 91.3% of cases.

Conclusion:
Foreign-body aspiration is not rare, even in adults who do not have predisposing factors. Iatrogenic events accounted for about 40% of all cases of foreign body aspiration. In adults, flexible bronchoscopy is relatively safe and has a high success rate for foreign-body removal.
