The role of flexible bronchoscopy accomplished through a laryngeal mask airway in the treatment of tracheobronchial foreign bodies in children

We here present our experience with children who underwent flexible bronchoscopy for removal of inhaled tracheobronchial foreign bodies under general anesthesia via a laryngeal mask airway (LMA). A total of 24 (16 male and 8 female, mean age: 30.75 ± 29.68 months) patients who underwent flexible bronchoscopy under general anesthesia using a LMA for suspicion of tracheobronchial foreign bodies between July 2016 and April 2018 were retrospectively reviewed. The mean duration of admission to hospital was 162.56 ± 309.56 h. Sixteen (66.7%) patients were found to have tracheobronchial foreign bodies. All procedures were successfully accomplished through a LMA by using basket forceps, a Fogarty catheter and a suction without any need for rigid bronchoscopy. 11 (68.7%) of tracheobronchial foreign body locations were right bronchial, 3 (18.8%) were left bronchial and 2 (12.5%) were tracheal. The types of extracted tracheobronchial foreign bodies were organic in 14 (87.5%) and non-organic in 2 (12.5%). There were no complications except laryngeal edema noted in 2 (8.3%) patients, relieved within 48 h. The mean time of postoperative hospitalisation was 2.42 ± 0.97 days. Flexible bronchoscopy accomplished through a LMA is a safe, easy and effective technique, not only as a diagnostic procedure, but also as the initial therapeutic modality for retrieving tracheobronchial foreign bodies in children with high success and low complication rates. With further reports aforementioned, we hope that the flexible bronchoscopy will become a standard method in children.
