AIM:To compare a first diagnostic procedure of transbronchial needle aspiration(TBNA)with selection of endoscopic ultrasound-guided fine-needle aspiration(EUS-FNA)or TBNA for mediastinal lymphadenopathy.METHODS:Sixty-eight consecutive patients with mediastinal lymphadenopathy on computed tomography(CT),who required cytopathological diagnosis,were recruited.The first 34 underwent a sequential approach in which TBNA was performed first,followed by EUS-FNA if TBNA was unrevealing.The next 34 underwent a selective approach where either TBNA or EUS-FNA was selected as the first procedure based on the CT findings.RESULTS:The diagnostic yield of TBNA as the first diagnostic procedure in the sequential approach was 62%.In the selective approach,the diagnostic yield of the first procedure was 71%.There was no significant difference in the overall diagnostic yield,but there were significantly fewer combined procedures with the selective approach.CONCLUSION:Selecting either EUS-FNA or TBNA as the first diagnostic procedure achieved a comparable diagnostic yield with significantly fewer procedures than performing TBNA first in all patients.

METHODS: Sixty-eight consecutive patients with mediastinal lymphadenopathy on computed tomography (CT), who required cytopathological diagnosis, were recruited. First 34 underwent a sequential approach where which TBNA was performed first, followed by EUS-FNA if TBNA was unrevealed. The next 34 underwent a selective approach where either TBNA or EUS-FNA was selected as the first procedure based on the CT findings .RESULTS: The diagnostic yield of TBNA as the first diagnostic procedure in the sequential approach was 62%. In the selective approach, the diagnostic yield of the first procedure was 71% .There was no significant difference in the overall diagnostic yield, but there are significantly fewer combined procedures with the selective approach. CONCLUSION: Selecting either EUS-FNA or TBNA as the first diagnostic procedure achieved a comparable diagnostic yield with significantly fewer steps than performing TBNA first in all patients.
