Evaluation of electromagnetic navigational bronchoscopic biopsy of lung lesions performed by a thoracic surgical service.

Thoracic surgeons can perform electromagnetic navigational bronchoscopy safely, with minimal morbidity and with good diagnostic yields. Accuracy increases with the presence of a bronchus sign and increasing lesion size. Patients with larger tumors and the bronchus sign may be candidates for this approach to biopsy. Further work is required to define the role of electromagnetic navigational bronchoscopy in the diagnosis of pulmonary lesions.
