##plugins.themes.vojs.article.main##
Abstract
Objective: Analyze diagnoses and indications before bronchoscopy, evaluate results after flexible bronchoscopy (FB)
Methods: Descriptive study of 1643 cases of FB over a period of 2 years from January 1, 2022 to December 30, 2023 at the Pediatric Respiratory Diseases Central of Viet Nam National Children’s Hospital.
Results: 1643 cases of children from 1 month to 16 years old were performed flexible endoscopy with 1296 cases for diagnostic purposes (78.9%) and 347 cases (21.1%) for interventional bronchoscopy. The main reasons for FB were abnorminal airway (tracheal stenosis, wheezing, prolonged stridor) (30.3%), persistent and recurrent pneumonia (27.4%), and suspected foreign body in airway (11.6%). Results: airway abnormalities (51.9%), including: subglottic stenosis/tracheobronchial stenosis due to scarring (30.4%), malacia laryngeal cartilage (19.5%), malacia bronchial (13.2%). Most common interventional procedures: narrow scar dilation (142 cases), airway foreign body removal (98 cases). Bacteria isolated in bronchoalveolar lavage: Pseudomonas aeruginosa 21.5%, Klebsiella pneumonia 16.9%, Klebsiella aerogenes 15.4%, Streptococcus pneumonia 10.0% of total cultured specimens.
Conclusion: FB is an important tool in the diagnosis and treatment of respiratory diseases, fnding airway anatomical abnormalities, taking specimens for microbiological causes, and providing interventional treatment to resolve obstruction airway.
