Value of EBUS-TBNA in diagnosis of lung cancer and its complications / 实用医学杂志

ABSTRACT

Objective To investigate the value of EBUS-TBNA (endobronchial ultrasound-guided trans-bronchial needle aspiration) in diagnosis of lung cancer and analyze its complications. Methods A retrospective study was carried out in our hospitalfrom March 2013 to March 2015. A total of 171patients received C-TBNA (Con-ventional transbronchial needle aspiration) first and got negative results. Therefore, they received EBUS-TBNA next. Weanalyzedthe sensitivity, specificity, accuracy of malignancy with EBUS-TBNA and positive (malignant) lymph node sites biopsied with EBUS-TBNAand the incidence of its complications. Results Lung cancer was proven in 107 patients who had received EBUS-TBNA, while 16 were benign cases. Thirty-onenegative patients received CT guided needle biopsy or surgeryfor finally pathology. Based on above statistical data , we calculated EBUS-TBNA′s sensitivity, specificity and accuracy in 88.42%, 100.00%and 94.21%respectively. A totalof 818 lymph nodes were punctured by EBUS-TBNA, 408 were malignancy. The rate of diagnosis for malignancy was 49.88%. The complica-tioncontained 1 in hemorrhage, 1 in infectionand no life-threatening conditionandno death. Conclusion The value ofdiagnosis in lung cancerisrelatively high with EBUS-TBNAin safety and efficient.
