This study is looking at how well different cleaning methods work for needles used during Endobronchial Ultrasound (EBUS) bronchoscopy. EBUS is a procedure where a doctor uses a special scope to look inside your airways and take samples from lymph nodes, often to check for lung cancer. The concern is that tiny cancer cells might stay on the needle after taking one sample and then contaminate the next sample, potentially leading to an incorrect diagnosis. This study will compare the usual cleaning method with an additional cleaning step called "purge cleaning" (flushing the needle into a separate vial). The goal is to see if this extra cleaning reduces contamination without affecting the ability to get a good diagnosis. You might be able to join if you are an adult aged 18 or older, are having an EBUS for suspected lung cancer, and will have samples taken from at least two lymph node areas.

Study design

This is an interventional study planning to enroll 204 participants. It will compare two different needle cleaning techniques.

What's involved

You would undergo a standard EBUS bronchoscopy procedure. The study will evaluate the cleaning techniques used during this procedure.

Compensation

Not stated in the trial record.

Follow-up

Your samples will be reviewed for contamination for up to 32 weeks after you join the study.
