TNB are performed on an autpatient basis by using only 1% lidocain local anesthesia.METHODS: TNB was performed in 148 patients, 44 (29,7%) women and 104 (71,3%) men, age 28- 82, average 74 years; changes in the thoracic wall, pleura, parenchyma et the lung and mediastinum.Needles that were used in the procedure were BardMagnum 18-19G x 200mm, and sample length was 19 mm. Needles were activated using BardMagnum automatic trigger, under RT control with the C-arm Ziehm-Vision.RESULTS: In 148 patients the TNB was done:View this table:Table 1. ResultsSuccess of the procedure was greater if the changes were bigger and closer to the thoracic wall. Total diagnostic success is 92,8%.Carcinoma bronchogenes was proven in 134 (90,5%) patients: carcinoma squamocelulare 62 (46,2%), adenocarcinoma 52 (38,8%), carcinoma macrocelulare 5 (3,7%), SCLC 15 (11,1%).Lymphoma - 5 (3,3%)TB – 2 (1,3%)Thymoma malignum - 1 (0,6%)Carcinoma metastaticum - 4 (2,7%)Mesothelioma - 2 (1,3%)Complications: pneumothorax - 4 (2,7%), hemoptysis - 8 (5,4%).CONCLUSION: TNB is safe and cheap diagnostic procedure for histological and/or cytological confirmation of changes in the lung and mediastinum. Sensitivity of TNB is 92,8% and specificity 100%. ER -
