Abstract:
Objective Analyze the clinical feature of patients failed for diagnosis through endobronchial ultrasound transbronchial needle aspiration(EBUS-TBNA).Optimize the indication and increase diagnosis rate of EBUS-TBNA.Methods A total of 669 patients failed for diagnosis of EBUS-TBNA were included.Fifty-three of them(7.92％) were not exactly diagnosed.Perioperation clinical data and clinical feature were collected and evaluated based on specific disease,lesion location,size and operator' s experience.Results The undiagnosis rate was higher in lymphoma (77.78％),tuberculosis (23.08％) and sarcoidosis(9.09％) when analyzed from specific diseases.If the lesion location was taken into consideration,15.38％ upper paratracheal lymph nodes(R2) could not be diagnosed exactly by EBUS-TBNA,and the bilateral hilar lymph nodes(15.00％ for right,11.54 for left) were followed.Size of the lesion was not associated with the diagnosis rate.The operator's experience could also affect the results.The undiagnosis rate was highest in the first 10 cases among all operators.After at least 10 EBUS-TBNA processes,the undiagonsis rate stayed near 7.50％,which was close to the average.Conclusion It is necessary to select suitable indications for EBUS-TBNA based on the disease,lesion location and operatior experience,and cooperate with mediastinoscopy to rise diagnosis rate.
