title: [Transesophageal echography in staging of bronchial cancers].
abstract: The kind of relation of central lung cancer (c) to the walls of the central pulmonary arteries (PA) and the aorta is an important information prior to operative or interventional (laser/afterloading) therapy. As computed tomography (CT) and angiography are often inaccurate in the assessment of PA-infiltration, we assessed the diagnostic value of transesophageal echography (TEE) in the staging of LC. 16 patients (pts.) were investigated using TEE in addition to CT or magnetic resonance imaging (MRI). Eleven pts. had central LC, 3 peripheral LC, 1 anterior mediastinal mass and 1 central pneumonia (cancer excluded). 2 pts. with central LC were unable to swallow the probe. In 9/9 pts. with central LC, 1/3 pts. with peripheral LC and 1 pt. with enlarged anterior mediastinum the tumour mass could be visualized. In the pt. with a centrally located infiltrate on chest radiogram TEE demonstrated enlarged hilar lymph nodes, but excluded a central tumour. Main PA branches could be identified in all 14/14 pts. Central left or right PA were compressed slightly in 3 pts. and severely in 2 pts., with a near total occlusion in one (confirmed by MRI/CT). TEE revealed PA-infiltration in 2 pts. and aortic wall infiltration in 2 other pts. Despite adjacent tumour mass aortic wall infiltration was excluded in 2 pts. Enlarged hilar lymph nodes could be demonstrated in 2/9 pts. with central LC, whereas CT/MRI showed enlarged mediastinal lymph nodes in 7/9 pts. In conclusion, TEE is able to visualize central lung cancer and gives useful additional informations about the kind of relation to central PA and the aorta.(ABSTRACT TRUNCATED AT 250 WORDS)
