The Application Value Of EBUS-TBNA In Patients With Mediastinal And Hilar Lymphadenopathy

Objective :At present,there are various diagnostic methods for mediastinal and hilar lymph nodes,but these detection methods have certain limitations.Therefore,it is meaningful to seek a safe and reliable method for detecting mediastinal and hilar lymph node lesions.Endobronchial ultrasound-guided transbronchial needle aspiration(EBUS-TBNA)is a new technology developed in recent years,which is safe and reliable.Therefore,this study aims to explore its clinical application value and safety in mediastinal and hilar lymphadenopathy.So as to provide a theoretical basis for clinical diagnosis of mediastinal and hilar lymph node lesions.Methods : Before the examination of 98 patients with mediastinal or hilar lymphadenopathy from February 2018 to June 2019 in the Chest Hospital of Xinjiang Uygur Autonomous Region,all patients' chests were subjected to computed tomography(CT)scans.Patients with lymph node lesions with a short axis greater than1 cm as shown by CT were included in this study.The patients were numbered according to the order in which they were seen.A total of 42 patients in group A underwent EBUS-TBNA examination of mediastinal or hilar lymph nodes,and a total of 56 patients in group B underwent TBNA examination.Record and compare the short axis,age,gender,success rate of lymph node puncture and incidence of complications in all patients with swollen lymph nodes.TBNA and EBUS-TBNA are diagnosed positively in mediastinal or hilar lymph node lesions for statistical analysis.Then compare the diagnostic accuracy of TBNA and EBUS-TBNA for different diseases.Results :1.There is no obvious difference in general data(lymph node short axis,age,gender,etc.)between patients in group A and group B.The baselines are consistent and comparable.2.Among 98 patients,the diagnosis rate of TBNA was 85.71% and the complication rate was 17.86%;the diagnosis rate of EBUS-TBNA was 92.86% and the complication rate was 2.38%.EBUS-TBNA has a higher diagnosis rate and higher safety.3.EBUS-TBNA and TBN have high diagnostic value in the diagnosis of benign and malignant lesions in both groups,especially in malignant diseases,EBUS-TBNA has a higher positive diagnosis rate,but statistical analysis There is no obvious difference between the two groups.Because of the small number of cases,benign lesions may cause little difference between the two groups.
