The aim of this retrospective study was to review the clinical characteristics, outcomes and factors associated with success in adult patients who underwent flexible or rigid bronchoscopy for airway FB removal. Methods: We retrospectively reviewed the records of 103 patients who underwent bronchoscopy to remove airway FB at Samsung Medical Center, South Korea from January 1999 to March 2017. Results: The median patient age was 64 years, and 70% were males. Among the 54 patients who underwent flexible bronchoscopy as first-line treatment, 43 (80%) patients had their FB successfully removed. Previous attempts at other hospitals was significantly associated with failed flexible bronchoscopy [9/11 (82%) vs . 3/43 (7%), P vs . 5 days, P=0.074) and peripherally located airway FB [9/12 (75%) vs . 23/48 (48%), P=0.115] were factors that trended towards flexible bronchoscopy failure. All of the 59 patients who underwent rigid bronchoscopy had their FB successfully removed. Rigid bronchoscopy was preferred to flexible bronchoscopy in patients with no comorbidities [38/59 (64%) vs . 18/44 (41%), P=0.018], previous attempts at other hospitals [34/59 (58%) vs . 4/44 (9%), P vs . 5 days, P vs . 21/49 (43%), P Conclusions: Our data suggest that previous failed attempts and delayed diagnosis are associated with flexible bronchoscopy failure. However, rigid bronchoscopy could be effective in removing an airway FB even in these cases. Further studies to identify factors to facilitate optimal patient selection will minimize failure rates and optimize resource utilization. UR - https://jtd.amegroups.org/article/view/26309
