Endobronchial ultrasound in pediatric pulmonology.
Endobronchial ultrasound (EBUS) is a recently introduced technique that has significantly advanced bronchoscopic techniques in adult medicine. Use of ultrasound allows far more accurate localization and sampling of both peripheral pulmonary, as well as mediastinal and hilar lesions. This has led to greater diagnostic success, with a reduced rate of complications. Its performance characteristics in adult populations are equivalent to surgical procedures previously considered gold standard, but it has dramatically reduced morbidity and mortality among patients requiring invasive diagnostic procedures, when compared to surgical approaches. We describe the types of EBUS in clinical use, the method of use, the clinical indications for each procedure, and the potential role for EBUS in pediatric pulmonology. Radial probe EBUS is used in the investigation of peripheral lung lesions and could be adopted in children to achieve accurate biopsy of such lesions. Linear probe EBUS allows minimally invasive biopsy of mediastinal and hilar lesions. It has potentially greater performance characteristics than current biopsy techniques, with no significant complications reported to date. It may be useful in the diagnosis of lymphoma, or neurogenic tumors, as well as many other diseases resulting in mediastinal or hilar lymphadenopathy. EBUS is a minimally invasive technique that allows tissue sampling of peripheral lung lesions, or mediastinal/hilar masses, with a high diagnostic accuracy, and a significantly lower morbidity and mortality than alternative approaches. The indications for and the use of EBUS in pediatric patients is certain to increase in the future.
