Review Meta Analysis
Efficacy and safety of conventional transbronchial needle aspiration in sarcoidosis: a systematic review and meta-analysis.
Flexible bronchoscopic procedures are currently the most often employed technique for demonstrating granulomatous inflammation in sarcoidosis. Conventional transbronchial needle aspiration (TBNA) has been used for over 3 decades; however, it remains an underutilized technique, primarily due to the wide variations in the reported success rates and unconfirmed safety concerns. Herein we perform a systematic review and meta-analysis of studies to estimate the diagnostic yield and safety of TBNA in sarcoidosis. ⋯ TBNA is an efficacious and safe procedure in the diagnosis of sarcoidosis. The performance of TBLB adds to the efficacy of TBNA. Hence, a combination of TBNA and TBLB should be routinely employed in diagnosis of sarcoidosis in those with enlarged mediastinal lymph nodes.
