RESUMEN
Background: A great deal of interest in transbronchial needlespiration (TBNA) lies in its utility as a staging tool in patientswith bronchogenic carcinoma. The aim of this study toevaluated the diagnostic yield of TBNA in cases of lungcancers and mediastinal masses or adenopathy.Materials & Methods: The study was carried out and datawere gathered in a prospective fashion and all the data werereviewed retrospectively. Samples were collected from allpatients bronchial washings (BW), brush biopsy (BB), EBB,and TBNA. All TBNA specimens were sent for cytologicevaluation without ROSE as per recommended guidelines.Results: The mean age of studied cases was 58.07 years. Thecommon radiological presentation on x-ray chest was masslesions in 76.66%, mediastinal widening 60%, consolidation26.66% and SPN 3.33% of cases. The diagnostic yield ofvarious bronchoscopic procedure were 27% by BW, 47% byBB, 60% by EBB, 87% by TBNA.Conclusion: We conclude that the overall diagnostic yield offlexible bronchoscopy procedure is increased in patients withEML or SPD by the addition of TBNA. The TBNA is a safeprocedure that should be routinely used to increase diagnosticyield in patients with EML or SPD. In cases of SPD, TBNAshould be considered the procedure of choice.
