Predictors of Positive Bronchoscopy in Children with Suspected Foreign Body Aspiration: A Retrospective Cross-Sectional Study
Abstract
Highlights What are the main findings? Air trapping on chest radiography showed the strongest association with foreign body detection during bronchoscopy, although the estimated effect was imprecise. Nearly one-quarter of children with bronchoscopically confirmed foreign body aspiration had normal chest radiographs, indicating that normal radiographic findings do not exclude the diagnosis. What are the implications of the main findings? Clinical decisions regarding bronchoscopy should integrate patient history, physical examination, and radiographic findings rather than rely on any single predictor. These findings should be interpreted within the selected population of children who had already undergone bronchoscopy. Abstract Objective: Foreign body aspiration (FBA) is a common pediatric emergency, and bronchoscopy remains the diagnostic and therapeutic gold standard despite its invasive nature and associated procedural risks. This study aimed to evaluate the clinical and radiographic factors associated with foreign body detection during bronchoscopy in children undergoing bronchoscopy for suspected FBA. Methods: This single-center, retrospective, cross-sectional study included children aged 0–18 years who underwent bronchoscopy for suspected FBA at a tertiary pediatric emergency department between January 2010 and January 2026. Of 120 eligible patients, 25 were excluded because of incomplete medical records, resulting in a final cohort of 95 children. Predictors of…
