Transesophageal pulmonary nodule biopsy using endoscopic ultrasonography.

Objective: Parenchymal pulmonary nodules located in proximity to the mediastinum, vertebral column, major vessels, or behind the heart can be technically challenging and dangerous to biopsy using traditional image-guided techniques. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) can be used to access some of these difficult to reach lesions. The purpose of the present study was to report our experience with this technique in a consecutive cohort of selected patients.
