Bronchoscopy is endoscopic examination of airways that allows both diagnostic and interventional procedures in the evaluation of airway disease in children. It can be performed with either rigid or flexible instruments, depending on the particular needs of patients and skills of bronchoscopist. In addition to visualization of airways, bronchoscopy enables to obtain specimens form lungs and distal airways.Bronchoalveolar lavage (BAL) yields samples from surfaces of the alveoli and aids differential diagnosis of various pulmonary disease. Foreign body removal and examination of anatomy and dynamics of airways are also common indications of bronchoscopy in children. Improvement in the technology, endoscopic instrumentation allows detailed evaluation and interventional manipulation of airway lesions in small children. Although bronchoscopy is considered as a safe procedure, obstruction of airway may challenge and require special endoscopic skills with appropriate instrumentation. This review is aimed to outline the role of bronchoscopy in diagnosis airway disease in children.

“…Su principal ventaja sobre la traqueoplastia con parche es la inmediata reconstrucción con tejido traqueal nativo, la rá-pida reepitelización de la herida, la menor tendencia al desarrollo de tejido de granulación y la posibilidad de una rápida y precoz extubación, así como de un adecuado crecimiento traqueal. Para aquellos pacientes con estenosis complejas que no son susceptibles de tratamiento quirúrgico, o bien esta opción ha fracasado, se recomienda la utilización de tutores [37].…”

Tracheal stenting currently using non-degradable stents is commonplace for treatment of trauma, prolonged intubation related adult airway obstructions, and pediatric patientsassociated tracheal stenosis conditions. Degradable tracheal stent placement will avoid complications of stent removal and restenosis. Widespread reports exist on degradable magnesium alloys success for orthopedic and cardiovascular applications but none to date for intra tracheal use. This research explores the use of pure Mg, AZ31, and Mg-3Y alloys for degradable tracheal stent assessment. In vitro evaluation of magnesium, prototype stents in a bioreactor simulate the airway environment and corrosion. Micro-CT imaging and biocompatibility evaluation helped assess the 24-week degradation of intraluminal alloy stents following implantation in a rat tracheal in vivo bypass model. Histological analysis indicate tissue response of the harvested stented trachea segments after each time point. Corrosion studies for each alloy indicate significant differences between the simulated and control in vitro conditions. AZ31 exhibited the lowest volume loss of 6.8% in saline, while pure Mg displayed the lowest volume loss of 4.6% in simulated airway fluid (SAF), both at 1-week time points. Significant differences in percentage of total volume lost after 6 months were determined between the alloys over time. MgY alloy displayed the slowest corrosion losing only 15.1% volume after 24 weeks of immersion. Additionally, in vitro magnesium alloy corrosion was not significantly different from the percentage of total volume lost in vivo at 1-week time point. The study demonstrates promise of magnesium alloys for intraluminal tracheal stent application albeit viability of a clinically translatable model warrants further studies.

The role of airway stenting in pediatric tracheobronchial obstruction☆

Abstract: Although the results were based on a small series, placement of stents in the pediatric airway to treat tracheobronchial obstruction seems to be safe and effective. Stenting is a satisfactory therapeutic option when other procedures have failed or are not indicated.
