Aim: EBUS TBNA is an important diagnostic procedure for the intrathoracic lymph nodes. 21 G, 22 G and 25 G needles are used for sampling. Better samples can be expected to be taken via 21 G needle, as the inner diameter of 21 G needle is larger. However, the results of the studies comparing 21 G and 22 G needles are controversial. Methods: The study population consists of patients with EBUS TBNA performed via 21 G needles (Group 1; n=40) and the patients for whom 22 G needles used (Group 2; n=40). The data of patients were retrospectively analyzed. ROSE was performed for all samples.Results: The sensitivity, specificity and diagnostic accuracy of the procedure with 21 G needle was 95%, 85%, 93%, respectively. The diagnostic accuracy of 21 G needle was found to be higher than that of 22 G needle (93% versus 80%). In the procedure performed with 21 G needle, fewer samples were sufficient for the diagnosis than 22 G needle (r = 0.03, p <0.05).Conclusion: The diagnostic accuracy rate of 21 G needle was higher than 22 G needle. According to that result, it is better to prefer 21 G needle. With a 21 G needle, a smaller number of sample was sufficient for diagnosis than a 22 G needle. Diagnostic opportunity with less sample obtained with 21 G needle may provide time advantage to the cytopathologist who performs ROSE. Due to this advantage, in EBUS TBNA with ROSE, 21 G needles can be prioritized. ; Amaç: EBUS TBNA intratorasik lenf nodları için önemli bir tanısal işlemdir. Örnekleme için 21, 22 ve 25 G iğneler kullanılır. 21 G iğnenin iç çapı daha geniş olduğu için daha iyi örneklerin alınması beklenir. Halbu ki, 21 ve 22 G iğneleri kıyaslayan çalışmaların sonuçları çelişkilidir.Yöntem: Çalışma grubu, 21 G (Grup 1; n=40) ve 22 G (Grup 2; n=40) iğne kullanılarak EBUS TBNA yapılmış hastalardan oluşmuştur. Hasta verileri retrospektif olarak analiz edilmiştir. Tüm örneklemlerde ROSE uygulanmıştır.Bulgular: 21 G iğnenin sensitivite, spesifite ve tanısal doğruluğu sırasıyla , idi. 21 G iğnenin tanısal doğruluğu 22 G iğneye ...
