Malignancy
NO
To determine the appropriate number of needle stroke movements per puncture in EBUS-TBNA.
Efficacy
The detectability of lesions in three groups according to the number of the stroke movements: the low-number group (20 times), the moderate-number group (25 times), and the high-number group (30 times).
1)Correlation between the detectability and size of lesions
2)The detectability of lesions of lung cancer and sarcoidosis.
3)The detectability of non-necrotizing granulomas in TBLB and EBUS-TBNA.
4)The rate of contraflow of blood in the EBUS-TBNA procedures
Observational
Not applicable |
Not applicable |
Male and Female
all patients with histologically proven lung cancer or sarcoidosis who had previously undergone EBUS-TBNA at the University of Miyazaki Hospital between April 2014 and July 2016.

We reviewed the EBUS-TBNA data of sarcoidosis (n = 29) and lung cancer (n = 99) patients. Using the data of their 43 sarcoidosis and 139 lung cancer lymph nodes, we evaluated the correlation between the detectability of granulomatous lesions or malignant lesions and the number of needle-stroke movements.
The number of needle stroke may influence the detectability of granulomatous lesions in sarcoidosis due to blood contamination caused by the contraflow of blood.
