Investigators
Eligibility Criteria
Inclusion Criteria
- •Patients age 18 and older
- •Patients presenting with peripheral pulmonary lesions 1-7cm in greatest diameter on axial CT or PET scan in need of bronchoscopic biopsy for clinical purposes
Exclusion Criteria
- •Patients who are unable to undergo flexible bronchoscopy as determined by the bronchoscopist prior to the procedure
- •Patients unwilling or unable to provide informed consent.
Outcomes
Primary Outcomes
Overall diagnostic yield (concentric and eccentric lesions) for peripheral pulmonary nodules
Time Frame: Receipt of cytology/histopathology results (approximately 7 days)
-To determine overall diagnostic yield (concentric and eccentric lesions) for peripheral pulmonary nodules utilizing using a standard of care combined approach of 4mm thin and 3mm ultrathin bronchoscopes with TBNA and radial EBUS and compare it to a historical baseline diagnostic yield of 60% established at Washington University School of Medicine (WUSM) when using TBNA and radial EBUS and a 4mm thin bronchoscope.
Secondary Outcomes
- Types of deficiencies associated with medical device(From start of procedure through end of procedure (day 1))
- Ability to successfully convert ultrasound images from eccentric to concentric view by exchanging the 4mm thin bronchoscope for the 3mm ultrathin bronchoscope(From start of procedure through end of procedure (day 1))
- Diagnostic yield of bronchoscopy utilizing a 3mm bronchoscope for eccentric lesions(Receipt of cytology/histopathology results (approximately 7 days))
- Incidence of related adverse events(Up to 4 days following procedure)
- Procedure time measured in minutes from oral scope insertion to scope removal upon completion of the bronchoscopy procedure(From start of procedure through end of procedure (day 1))
- Size of target lesions measured at the greatest diameter in centimeters(From start of procedure through end of procedure (day 1))
