Failures in emergency management of pediatric airway foreign bodies by rigid bronchoscopy: we have yet to complete our learning.

Background: Several children are affected by airway foreign body aspiration (FBA) resulting from life-threatening conditions. Choking has been considered the major symptom and is defined as airway blockage by a foreign body (FB), leading to marked morbidity or mortality. This retrospective study indicates the possibility of misdiagnosis or rigid bronchoscope (RB) failure, which is the standard gold method for extracting FB in the airway. Methods: Six children with airway FBA who failed treatment using RB between 2018 and 2019 were retrospectively studied. The inclusion criterion was a history of failure to extract FB using RB followed by flexible fiberoptic bronchoscopy (FFB). Results: In the present study, among 63 patients who had undergone rigid bronchoscopy, airway FBs were successfully removed in 57 (90.48%). Rigid bronchoscopy failed in 6 (9.52%) patients. The age of cases at the time of bronchoscopy ranged from 11 months to 13 years. FFB was performed to extract missing or remaining FBs and was done successfully in all patients. The patients made an uneventful recovery following FB extraction using the FFB method. Conclusions: It is not easy to diagnose and treat airway FB in children. Rigid bronchoscopy has been approved as a method to manage airway FB, but a negative bronchoscopy result must usually be interpreted carefully. FFB is applicable as a proper and relatively safe diagnostic and therapeutic tool in managing airway FBs among the pediatric population, especially in cases where rigid bronchoscopy was performed but missed or failed to extract the FB.
