Endoscopic removal of tracheobronchial foreign bodies: results on a series of 51 pediatric patients

Purpose: Rigid bronchoscopy (RB) is still considered the gold standard approach for the removal of airway foreign bodies (FBs) in children; however, flexible bronchoscopy (FOB) has recently been proposed both as diagnostic and therapeutic means. Our purpose was to evaluate the outcomes of FOB, associated with the Dormia basket, for the removal of FBs. Methods: Retrospective data about 124 children who underwent bronchoscopy for the suspicion of a FB aspiration between January 2008 and January 2019 in our department were collected. Results: In a total of 51 cases, FBs were removed through FOB or RB associated with forceps or Dormia basket. Male to female ratio was 1.8:1, mean age 30 ± 26.1 months. Thirty-four (67%) FBs were directly removed through FOB, in most of the cases using Dormia basket and twelve (23%) patients underwent RB. The overall left-versus-right distribution was 57% vs. 43%. The mean retrieval procedural time was 36.29 ± 24.99 min for FOB and 52.5 ± 29.74 min for RB; the success rate of the procedures was 97% vs. 67%. Conclusion: FOB can be used not only as a diagnostic procedure, but also as the first method for the removal of airway FBs. The Dormia basket is a useful tool, especially to remove peripherally located FBs.
