ROLE OF ULTRASOUND AND CT GUIDED FNAC AND TRU-CUT BIOPSY IN THE DIAGNOSIS OF INTRA-THORACIC LESIONS.

Abstract

Introduction: Image guided per-cutaneous trans-thoracic FNA and Tru-cut biopsy are gaining popularity since last few decades among the pulmonologists for tissue diagnosis of intra-thoracic lesions. These procedures have high diagnostic yield and are less invasive, have less complication rate in comparison to procedures like surgical lung biopsy, bronchoscopy or thoracoscopic guided lung biopsy. Aim: The aim of this prospective observational study was to determine the diagnostic yield and complications of USG guided and CT guided Fine needle aspiration and Tru cut biopsy in cases with intra- thoracic lesions. Materials and methods: In this observational study 49 patients were selected during the one-year study period after getting informed consent. CECT Thorax was done in all cases to evaluate the location, type of lesions. In 14 cases with peripheral pulmonary lesions abutting chest wall and pleural lesions both USG guided FNAC and Tru cut biopsy was done. CT guided FNAC and Tru cut biopsy was done in rest of the 35 cases. Results: Diagnostic yield of USG guided FNAC was found to be 64.3% and CT guided FNAC was 62.86%. Diagnostic yield of CT guided Tru cut biopsy in this study was 91.43% and USG guided Tru cut biopsy was 92.9%. complication rate of both USG and CT guided procedures were low. Conclusion: Both USG guided and CT guided FNAC and Tru cut biopsy are efcient diagnostic procedures for intra-thoracic lesions. Tru-cut biopsy procedure is superior to FNAC procedure for denitive diagnosis
