Background. Mediastinoscopy is a widely used technique in the diagnosis of mediastinal disease and the staging of bronchogenic carcinoma. Its efficacy in the preoperative staging of lung cancer is well-established, with a procedural sensitivity of greater than 90% and specificity of 100%. Mediastinoscopy can also establish the diagnosis in greater than 90% of mediastinal disease. We conducted a retrospective study of mediastinoscopy performed at our institution between 1998 and 2001 to evaluate the safety and efficacy of mediastinoscopy. Methods. We collected 100 consecutive mediastinoscopies performed in Thoracic Division of Taipei Veterans General Hospital between 1998 and 2001. The indications for mediastinoscopy included mediastinal mass or lymphadenopathy and the staging of lung cancer. Some patients had the undetermined lung mass with enlarged mediastinal lymph node. Results. There were 69 men and 31 women aged from 13 to 87 (mean 60.9). Sixty-seven patients had mediastinoscopy for the staging of lung cancer, 29 patients for diagnosis of mediastinal mass or lymphadenopathy, and 4 patients for undetermined lung mass with mediastinal lymphadenopathy. Among the patients with mediastinal disease, sarcoidosis was diagnosed in 13 patients, and lymphoma in 5 patients. N2 or N3 nodal metastasis was revealed in 38 of 67 patients who had lung cancer. Fifteen patients with negative mediastinoscopy proceeded to thoracotomy for tumor resection. Seventeen patients received neoadjuvant chemotherapy followed by resection. There were three complications, all due to bleeding, and no mortality. Conclusions. Mediastinoscopy is a safe and effective procedure for the diagnosis of mediastinal disease and the staging of lung cancer. In cases of lung cancer, mediastinoscopy can provide more accurate evaluation of mediastinal lymph node metastasis than conventional diagnostic tools like computed scan or magnetic resonance image with low morbidity and mortality.
