The aim of this work was to determine the role of video-thoracoscopy and mediastinoscopy for the diagnosis of lymph node enlargement in the mediastinum of unknown aetiology. From January 1992 to December 1993, 26 patients were seen for surgical biopsy of mediastinal lymph nodes. Relative localization and the requirement for an associated gesture determined the choice between axial mediastinoscopy, parasternal scopy and videothoracoscopy. Mediastinoscopy was performed for peritracheal or right hilar (Baréty) nodes and parasternal scopy for anterior mediastinal masses. Videothroacoscopy was performed when the lymph nodes were localized at the preceding sites or when an associated manoeuver was required. Mediastinoscopy was performed in 16 patients. Lymphorrea which subsided after 4 days occurred in one patient and the mean hospital stay was 2.6 days. Diagnosis was achieved in 15 cases. The delay from procedure to treatment was 11 days on the average. Parasternal scopy was used 3 times and gave the diagnosis in all cases. Videothoracoscopy was used for 7 patients including 2 cases with pulmonary biopsies. Diagnosis was established 7 times and the delay to treatment was 12 days. No diagnostic thoracotomie were performed during this period. When access to the mass to be biopsied is difficult with mediastinoscopy (aorto-pulmonary, subcarenal, triangular ligament) videothoracotomy can be useful. Post-operative follow-up is simple and a specific treatment can be instaured rapidly. Videothoracotomy should be an important supplementary method for mediastinoscopy and helping avoid thoracotomy.
