[Diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration in stage Ⅰ and stage Ⅱ of sarcoidosis].

Abstract
To evaluate the diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in stage Ⅰ and stage Ⅱ of sarcoidosis. There were 55 patients of sarcoidosis selected from January 2012 to October 2014 in the First Affiliated Hospital of Soochow University. The diagnostic positive rate and the positive rate in stage Ⅰ and Ⅱ patients with sarcoidosis through EBUS-TBNA, conventional transbronchial needle aspiration (cTBNA), endobronchial biopsy (EBB) combined with transbronchial lung biopsy (TBLB) were calculated. The positive rate of single lymph node puncture and the positive rate of different size of lymph node were compared. The difference of the positive rate of lymph nodes in different stations was checked. By calculating the diagnostic yield of EBUS-TBNA in sarcoidosis patients, the practicality and safety of EBUS-TBNA in diagnosing stage Ⅰ or stage Ⅱ sarcoidosis was assessed. Among 55 patients, 46 patients obtained positive results through EBUS-TBNA or cTBNA. There were 18 patients who had only received EBUS-TBNA among a total of 55 patients diagnosed with sarcoidosis, positive results appeared in 17 cases, while cTBNA was 9/15. There were 20 cases diagnosed in which both had EBUS-TBNA and cTBNA. The diagnostic rate of cTBNA combined with EBB and TBLB was 25/26, while combined with EBUS-TBNA was 21/21. Totally 90 lymph nodes were punctured by EBUS-TBNA, in which 65 lymph nodes got the positive results (65/90) while 49 lymph nodes got the positive results by TBNA in 93 punctured lymph nodes (49/93). The diagnostic positive rate in the lymph nodes with a short diameter ≥2 cm was 33/37 by EBUS-TBNA, while it was 12/19 in those whose short diameter 1-<2 cm. By cTBNA, the diagnostic positive rate was 15/26 and 11/28. No serious adverse events occurred. The diagnosis of sarcoidosis in stage Ⅰ and stage Ⅱ by EBUS-TBNA is safe and effective, while choosing the most noticeable swelling lymph node to puncture is recommended. Combining the EBUS-TBNA with traditional bronchoscope technology can obtain a further higher diagnostic efficiency.
