Complete endo-echo staging of the mediastinum
A tissue diagnosis of mediastinal nodes is frequently needed for accurate lung cancer staging as well as the assessment of mediastinal masses. Non-invasive imaging techniques such as CT, MRI, PET and PET-CT provide some answers but no tissue diagnosis. TBNA has a high impact on patient management. Unfortunately, TBNA remains underused in current daily practice, mainly due to the lack of real-time needle visualization. The introduction of echoendoscopes has overcome this problem. Endobronchial ultrasound-guided TBNA (EBUS-TBNA) allows realtime controlled tissue sampling of paratracheal, subcarinal and hilar lymph nodes. Mediastinal lymph nodes located adjacent to the esophagus can be assessed by transesophageal ultrasound-guided fine needle aspiration (EUS-FNA ). Owing to the complementary reach of EBUS-TBNA and EUS-FNA in assessing different regions of the mediastinum, recent studies suggest that complete and accurate mediastinal staging can be achieved by the combination of both procedures.
