Learning curve for endobronchial ultrasound‑guided transbronchial needle aspiration: experience of a community‑based teaching hospital.

Endobronchial ultrasound‑guided transbronchial needle aspiration (EBUS‑TBNA) is a minimally invasive procedure. This procedure is useful for nodal staging of lung cancer and evaluating mediastinal lymphoma and granuloma. The present study was a retrospective analysis of our experience when EBUS‑TBNA was initially implemented.
