Stylet Versus no Stylet in Endobronchial Ultrasound Transbronchial Aspiration (EBUS-TBNA)
This research study compares two ways to biopsy lymph nodes in the chest using endobronchial
ultrasound-guided transbronchial needle aspiration" (EBUS-TNBA). During a EBUS-TBNA
procedure, the patient is sedated, and a flexible camera and ultrasound probe is inserted
through the mouth into the large airways of the chest, allowing us to see (via ultrasound)
and biopsy the lymph nodes in the chest.
The purpose of this research study is to determine if the EBUS-TBNA procedure can be made
simpler. In today's practice, the biopsy needle has two parts, 1) the needle itself and 2)
an inner stylet that runs through the middle of the needle. Because many other biopsy
needles (such as the needles used in breast biopsy and different types of lung biopsy
needles) do not use an inner stylet, the investigators do not think the use of a stylet is
necessary. If this step can be safely eliminated without decreasing the effectiveness of the
procedure, this could shorten the procedure (saving time). This study is deigned to formally
test the hypothesis that a stylet is not necessary in EBUS-TBNA.
