To clarify the usefulness of the diagnosis and treatment of mediastinal masses, by video-assisted thoracoscopic surgery (VATS), we performed a retrospective multi-institutional study to delineate the type of approach, histopathology, and complications associated with these entities.We analyzed 150 patients who underwent the VATS procedure at several institutions between 1991 and 1999.VATS resections were performed using various combinations of the "pansternal approach." The unilateral thorax approach was applied in 135 patients, the bilateral thorax approach combined with the suprasternum approach in seven patients, the unilateral thoracic approach combined with the supraclavicular approach in three patients, the infrasternal approach in three patients, and the bilateral thoracic approach combined with both the infrasternal and the suprasternal approaches in two patients. Thoracoscopic resections or biopsies diagnosed 140 benign and 10 malignant mediastinal masses. There were operative complications in nine patients (6%). Eight patients (5.3%) were converted to conventional thoracotomy.VATS is a safe, effective, minimally invasive technique that can facilitate the resection of mediastinal masses when the pansternal approach is applied as appropriate for the location of the tumor.
