The Tools of the Trade - Uses of Flexible Bronchoscopy.
Bronchoscopes have markedly improved the diagnosis as well as therapy in pediatric pulmonary disorders. Two types of bronchoscopes are available; flexible and rigid, with their own advantages and disadvantages. Depending on the clinical need and availability of skills, choice is made between the two. Typically, rigid scopes are largely used by the surgeons (pediatric or otolayngologists) while flexible bronchoscope stays in the domain of the pediatric pulmonologist and intensivists. Rigid scopes may be more versatile than flexible bronchoscopes in removing the foreign bodies from the airway. Flexible bronchoscopes on the other hand can even be introduced through an endotracheal tube. At times, use of both scopes may be required in a given patient for optimal results. Bronchoscopes give us a means to visualize the inside of the airway, which can be very informative for assessing various pathologies affecting the airways. Apart from the visualization of the parts of the airway tree and their structure as well as patency, it can also be used to take tissue biopsy specimens, collect secretions from the airways and bronchoalveolar lavage which can also get cellular elements from the distal alveoli. In the past few decades, more and more instruments are being used for expanding the utility of flexible bronchoscope for interventions ranging from bronchial toilet, foreign body removal, airway stenting and lasers or cryotherapy for airway lesions. The perinatologists have opened up more vistas and thrown newer challenges for using fiberoptic bronchoscopy (FB) for in utero tracheal occlusion in cases with diaphragmatic hernia. The vast applications of this tool makes it very relevant to pulmonary investigations and therapeutics.
