Endobronşiyal Ultrasonografi Eşliğinde Gerçekleşirilen Transbronşiyal İğne Aspirasyonu biyopsi materyallerine histopatolojik yaklaşım


Aim: The aim of this study was to demonstrate the efficacy of the Endobronchial Ultrasound-Transbronchial Needle Aspiration (EBUS-TBNA) method with histopathological data and to determine the optimal management of the pro cess from the time of arrival of the materials to the diagnosis. Material and Method: In this study, EBUS-TBNA materials examined between 2015-2019 were reviewed retrospectively. There were 552 cases within 4 years and these cases were included in the study. Results: In our study, the sensitivity, specificity, positive predictive value (PPD) was 90%, negative predictive value (NPD) was 98%, 90%, 98% respectively. After the first procedure, 75% of the biopsy specimens obtained after the second EBUS-TBNA could be effectively diagnosed in cases previously diagnosed as insufficient tissue samples for diagnosis. In order to give an effective diagnosis to biopsy materials, it was seen that an average of 2 biopsy glasses (one H&E glass + 1 serial section) was sufficient for the biopsy materials and 12-13 glasses were sufficient for the cytology materials. Conclusion: The findings of our study support that EBUS-TBNA method is a very important method in diagnosis and staging. Considering that the complication rate is low, it may be the first method to be selected after chemo-radiotherapy and before the surgical procedure. In addition, in cases where the EBUS-TBNA method results in insufficient material for diagnosis, the same method could again be considered first due to the low risk of complications. Finally, in order to shorten the time spent on the evaluation of cytology glasses and reduce the cost per glass, we think that a tissue biopsy accompanied by the cytology material spread on 12-13 glasses will be sufficient.
