- W2015884345 abstract "Despite its proven efficacy, transbronchial needle aspiration (TBNA) remains an underutilized technique for sampling enlarged mediastinal lymph nodes in the staging of lung cancer. Previous investigators have reported on TBNA experience, but without mentioning individual learning curves related to lymph node size in pulmonologists experienced in bronchoscopy.The aim of this study was to evaluate the TBNA learning curve in a group of pulmonologists already experienced in bronchoscopy, and to relate their yields to lymph node size and location.Data on TBNA yield and related lymph node size were collected retrospectively for five individual pulmonologists.The diagnostic yield of five pulmonologists who started to perform TBNA was evaluated over the first 32 months. TBNA was performed on 138 lymph nodes in 119 patients. The overall diagnostic yield was 77% (range 67-91%). The average diagnostic yield increased from 77% at the start of the learning curve to 82% after 32 months of experience. It was related to lymph node size, but not to lymph node location. The average lymph node size was 22 mm.Satisfactory results were obtained immediately after introduction of TBNA in the bronchoscopy workup. There is no significant TBNA learning curve. The diagnostic yield was related to lymph node size but not to lymph node location." @default.
