The goal of this study is to evaluate the feasibility and safety of navigation guided virtual transthoracic needle biopsy combined with navigational bronchoscopy for the diagnosis of peripheral pulmonary nodules (PPN).
Accessing peripheral pulmonary nodules is problematic because they are often not visible endobronchially, not large enough to be visualized by x-ray fluoroscopy for transbronchial biopsy (TBBx), and/or do not lie within an accessible airway. In this study, investigators hope to evaluate new technologies to aid in PPN biopsy using navigation bronchoscopy (NB) combined with navigation transthoracic needle aspiration (N-TTNA) sampling of a PPN. Patients meeting inclusion criteria who consent will undergo a convex Endobronchial Ultrasound (EBUS) bronchoscopy for evaluation and sampling of the mediastinum and hilum. Following this, NB will be performed with an ultrathin bronchoscope (4mm outer diameter with a 2 mm working channel) with R-EBUS and fluoroscopy. If the lesion is localized by NB and/or radial EBUS in conjunction with NB, TBBX will be taken. At the conclusion of TBBX sampling, a fluoroscopic evaluation to assess for the presence of pneumothorax will be performed and if one is present, appropriate clinical measures will be taken at the discretion of the treating team (tube thoracostomy, observation, etc.) and no further sampling techniques will be utilized. If the lesion was not able to be localized via NB and/or the physician feels insufficient sample was acquired for diagnosis and there is no evidence of pneumothorax, the patient will undergo N-TTNA at the same PPN during the same procedure time. It is envisioned that between 8-12 patients will require a N-TTNA to complete diagnosis.

Positive Diagnostic Yield of Bronchoscopic Biopsy of Electromagnetic Guidance Trans-thoracic Needle Aspiration (ETTNA) Alone
Positive diagnostic yield of bronchoscopic biopsy of Electromagnetic Guidance Trans-thoracic Needle Aspiration (ETTNA) alone was defined by participants having benign or malignant pathology.
Time frame: Approximately 1 week upon receipt of pathology report
Positive Diagnostic Yield of Bronchoscopic Biopsy of ETTNA + EBUS + NB
Positive diagnostic yield of bronchoscopic biopsy of ETTNA + EBUS + NB was defined by participants having benign or malignant pathology.
Time frame: Approximately 1 week upon receipt of pathology report
