ABSTRACT

BACKGROUND
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) technique provides a complementary assessment of the areas of mediastinal lymph gland involvement, and permits sampling of suspected humor nodes. But, the quality of EBUS-TBNA in assessing all areas of mediastinal humor nodes is small better-known and it looks that such assess depends on numerous factors associated with the patient’s condition and particularly the characteristics of native humor nodes. we tend to aimed to guage the utility of EBUS-TBNAin assessing mediastinal humor nodes and also the factors related to this utility.
METHODS
This cross-sectional study was performed on forty patients suspected to mediastinal pathology scheduled for assessment by EBUS-TBNA and mediastinoscopy. The diagnostic yield of EBUS-TBNA to mediastinal humor nodes was evaluated and non diagnostic cases evaluated by mediastinoscopy.
RESULTS
In analysis with EBUS-TBNA, the diagnostic yield of EBUS in assess to mediastinal humor nodes, as well as thirty four out of forty cases was adequate eighty fifth. the scale of lymph gland (lower than 10mm), the realm of sample (left and right higher paratracheal), and also the nature of the lymph gland sample (benign type) were related to lower diagnostic yield for EBUS-TBNA.
CONCLUSION
The diagnostic yield of EBUS in assessing mediastinal humor nodes for sampling and identification is eighty fifth. This profit is anticipated within the case of lesionslarger than ten millimetre, lesions of a malignant nature, also as lesions within the inferior paratracheal and subcarinal stations.

Conclusion:As a final conclusion, the diagnostic yield of EBUS in assessing mediastinal bodily fluid nodes for sampling and identification is eighty fifth. This profit is predicted within the case of lesions larger than ten millimeter, lesions of a malignant nature, in addition as lesions within the inferior para cartilaginous tube and subcarinal areas
