Mediastinal staging--the role of endobronchial and endo-oesophageaL sonographic guided needle aspiration.

Conventional transbronchial needle aspiration (TBNA) is a valuable procedure but remains underutilised. Recently, imaging guidance such as CT fluoroscopy has created considerable interest. As CT fluoroscopy is cumbersome and exposes patients and staff to radiation, endosonographic imaging may be a better choice in providing guidance for TBNA or FNA in enlarged mediastinal Lymph nodes. Real-time imaging during the procedure is helpful and increases the yield.
