Per-Esophageal Needle Aspiration of Parenchymal Lung Lesions and Mediastinal Lymph Nodes Using an Endobronchial Ultrasound Bronchoscope

Summary

Background:

Transesophageal endoscopic ultrasound-guided fine-needle aspiration using a bronchoscope (EUS-B-FNA) allows clinicians to determine mediastinal staging and lung mass evaluation of lesions not accessible by endobronchial ultrasound (EBUS) or where endobronchial ultrasound-guided transbronchial needle aspiration might not be safe.

Objectives:

To evaluate the safety, diagnostic accuracy, and feasibility of EUS-B-FNA.

Methods:

The study comprised patients who underwent a pulmonologist-performed EUS-B-FNA of mediastinal lymph nodes and parenchymal lung lesions between June 2015 and September 2017 at the Carmel Medical Center, Haifa, Israel.

Results:

EUS-B-FNA was performed in 81 patients. The transesophageal procedure was performed for easier accessibility (49.4%) and in high-risk patients (43.3%). The most frequently sampled mediastinal stations were left paratracheal and sub-carinal lymph nodes or masses (38.3% and 56.7%, respectively). There were no complications (e.g., acute respiratory distress, esophageal perforation, or bleeding). An accurate diagnosis was determined in 91.3% of cases.

Conclusions:

Pulmonologist-performed EUS-B-FNA is safe and accurate for evaluating mediastinal and parenchymal lung lesions and lymphadenopathy. Diagnostic accuracy is high. EUS-B-FNA may allow access to sites not amenable to other forms of bronchoscopic sampling, or may increase diagnostic accuracy in patients where anatomic position predicts a low diagnostic yield.
