343. DIAGNOSTIC VALUE OF ENDOBRONCHIAL ULTRASOUND-GUIDED TRANSESOPHAGEAL NEEDLE ASPIRATION (EBUS-TENA) IN LESIONS ADJACENT TO BOTH THE TRACHEA/BRONCHUS AND ESOPHAGUS

Abstract Objective To investigate the clinical diagnostic value of endobronchial ultrasound-guided transesophageal needle aspiration (EBUS-TENA) in lesions adjacent to both the trachea/bronchus and esophagus Methods The clinical data of 12 patients who underwent EBUS-TENA from February 2019 to February 2022 were collected. The operative physicians and nurses worked closely with each other and meticulously cared the patients. The vital signs changes were observed and recorded, as well as intraoperative adverse events and the acquired specimens. Results All the 12 patients underwent surgery successfully, and hair-like tissue strips were obtained in each case. There were 8 cases of central lung cancer and 4 cases of mediastinal tumor. The preoperative vital signs scores showed no significant difference with the intraoperative and postoperative scores (P>0.05). A few complications occurred, including 2 case of mild cough, 2 case of nausea and vomiting, with no symptoms of severe cough and dyspnea, haemorrhage, mediastinal infection, pneumothorax, mediastinal emphysema and other complications. Conclusion EBUS-TENA has significant effect in successfully obtaining pathological tissue specimens especially for lesions adjacent to both the trachea/bronchus and esophagus, improving disease positive diagnosis rate, reducing patients discomfort and the risk of surgery.
