简要总结
The goal of this clinical research study is to compare the effectiveness of a smaller, 25-gauge needle when used in an endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) instead of a standard 22-gauge needle.
The safety of the needles will also be studied.
详细描述
As a part of participant's standard-of-care, participant will have a bronchoscopy of lesions on participant's lung nodules and/or lymph nodes before the EBUS-TBNA. Participant will sign a separate consent for the bronchoscopy.
If participant agrees to take part in this study, before participant's bronchoscopy, participant will be randomly assigned (as in the flip of a coin) to 1 of 2 study groups. This is done because no one knows if one study group is better, the same, or worse than the other group.
- If participant is in Group 1, participant will have the EBUS-TBNA performed by first using a 25-gauge needle, followed by a 22-gauge needle.
- If participant is in Group 2, participant will have the EBUS-TBNA performed by first using a 22-gauge needle, followed by a 25-gauge needle.
To perform an EBUS-TBNA, a needle is inserted into the affected area using ultrasound imaging to collect tissue from the lungs and lymph nodes. The doctor will use the imaging to guide the needle into the area.

结局指标
主要结局
Percentage of Lymph Nodes With Adequate Samples
时间窗: One to two hours.
The primary outcome was the proportion of concordance between the 22-gauge and 25-gauge needles in sample adequacy after two passes. The intervention group each of the lymph nodes sampled first with 25 gauge-needle, then the 22 gauge-needle. The Control Group each of the 200 lymph nodes were sampled first with the 22 gauge- needles, then the 25 gauge-needle. Sample adequacy was assessed after 2 passes using each needle in all participants and recorded.
次要结局
- Usability of the Needle(1-2 hours (Intra procedurally))
- Concordance With the Final Diagnosis(One to two hours)
