Compare the diagnostic yield and specimen quality of EBUS-FNA performed with and without suction applied
EBUS, FNA,Suction,Lung cancer
Safety and/or Efficacy Study
Eligibility and IRB
This is a randomized study comparing the diagnostic yield and specimen
quality of EBUS-FNA performed with and without suction applied in consecutive
patients with suspected malignant peribronchial masses or lymph nodes. All
patients will have 2 aspirations of the peribronchial lesion with suction
applied and 2 aspirations without suction performed in random order. The
diagnostic yield and specimen quality of the specimen obtained with the two
techniques will be compared.
Fifty consecutive patients undergoing EBUS at AUBMC for suspected malignancy will be enrolled.
Consecutive patients with suspected malignant peribronchial masses or lymph nodes undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-FNA) will enrolled. All participants will have 4 needle aspirations of each targeted peribronchial lesion. Two needle aspitations are performed while applying suction and 2 needle aspirations will be performed without applying suction in random order. the investigators will compare the diagnostic yield and the quality of the specimens obtained using the two techniques.

The lesion cannot be sampled because of intervening tumor or blood vessels.
