ABSTRACT
BACKGROUND: The role of Transesophageal bronchoscopic ultrasound-guided fine needle aspiration (EUS-B-FNA) in the diagnosis of malignant pulmonary lesions adjacent to the esophagus is a well-known procedure with high diagnostic yield. Moreover, it is indicated for lung cancer staging. Franseen needle tip is a crown-cut needle that allow to obtain tissue cores and provide huge amount of tissue for pathologist’s evaluation, moving from fine needle aspiration (FNA) to fine needle biopsy (FNB). Few data about EUS-B-FNB and Franseen needle tip are available in Literature.
METHODS: Between May 2022 and June 2024, 33 patients with lymphadenopathy who underwent EUS-B with Franseen needle tip were consecutively enrolled. Chest CT scan was performed prior procedure. Lymphnodes’ dimension at imaging and EUS-B were recorded. EUS-B-TBNB was performed with 22G or 25G needle size. Diagnostic yield and specimen adequacy (SA) for predictive markers were evaluated.
RESULTS: 22G needle was used in 18 patients and 25G in 15, and no statistically significant differences were observed between sex and age in the two groups. Overall Diagnostic Yield was 91% (30/33), with no statistically significant differences between 22G and 25G needle group (89% and 93%, respectively). SA for predictive markers was achieved in 20 of 23 patients (87%) with cancer diagnosis, with no significant differences between 22G and 25G group (P=0.59). No adverse events were observed.
CONCLUSIONS: EUS-B-FNB is a safe and an effective diagnostic method that should be performed in every bronchoscopy suite. Franseen needle tip provides high quality samples for pathologists, avoiding procedure repetition and/or more invasive procedures.
