Aims The utility of EUS- guided transesophageal core biopsy of lung tumors has been rarely investigated. Most prior reported cases were performed with fine-needle aspiration or with smaller caliber FNB- needles.The aim of our study was to evaluate the diagnostic utility and safety of transesophageal EUS-guided core biopsy of pulmonary tumors using 22 G Franseen-tip needle.

Methods Data was collected retrospectively from January 2019 to October 2019. All the patients had pulmonary masses close to or abutting the esophagus, detected on CT-scan. They were referred for EUS- guided biopsy after failure of bronchoscopy to establish tissue diagnosis or judged as unsuitable for bronchoscopy due to the location. Patients underwent endoscopic ultrasound with a linear scope (Fujifilm EG-580UT) and fine needle biopsy using 22G Acquire needle (Boston Scientific Corp.). The obtained material was assessed visually by the endoscopist without onsite cytologist.

Results Eleven patients (7 men, 4 women) underwent EUS-guided transesophageal core biopsy of lung masses during the study period. The procedure yielded tissue for histologic diagnosis in 100% of patients. Immunohistochemical analysis was possible in all cases. Non-small-cell lung cancer was proven in seven patients, small-cell lung cancer in two, metastatic lung disease in one and mesothelioma in one. No complication was encountered during the first 48 hours and after 30 days follow-up.

Conclusions EUS- guided core biopsy of lung masses using 22 G Franseen-tip needle is safe and established histologic diagnosis in all patients in this study. In cases of accessible lesions this procedure could be discussed as first-line diagnostic tool.
