Transbronchial needle aspiration: initial experience in routine diagnostic bronchscopy

Background: Transbronchial needle aspiration (TBNA) has been shown to be useful not only for the diagnosis and staging of lung cancer, its most widely studied indication, but also for many of other clinical indications. Despite this, it remains largely underutilized, mainly because of concerns with poor yield, safety, tack of experience of the bronchoscopist, and lack of cytopathological support. Objective: To study the clinical utility and yield of TBNA as an adjunct to other conventional procedures in diagnostic bronchoscopy at a centre that was relatively inexperienced with this technique, but where there was availability of rapid on-site evaluation (ROSE). Most of the major indications for TBNA in both malignant as well as benign disease were included. Setting: University Teaching Hospital naive to the procedure. Patient and methods: Forty-five consecutive patients who underwent TBNA as part of diagnostic bronchoscopy during a 2-year study period. Results: TBNA gave a yield of 65% for evaluation of mediastinal disease, both benign and malignant. The overall diagnostic utility for all indications was 71% and there were no complications. Conclusions: We conclude that TBNA is a useful and safe adjunct to diagnostic bronchoscopy in routine clinical practice. It has a satisfactory yield even with an inexperienced team, if used with ROSE. (C) 2003 Elsevier Ltd. All rights reserved.
