title: [Mediastinoscopy in 165 patients].
abstract: OBJECTIVE
  To investigate the value of mediastinoscopy in diagnosis of the thoracic diseases and the determination of the operative indication.
  
  
  METHODS
  From 1979 to 2000, 165 patients were given mediastinoscopy by local infiltration anesthesia (rare cases with additional vein bacic anesthesia). The exploration and biopsy were given to the neoplasms and lymph nodes around the trachea through the pretracheal interstice.
  
  
  RESULTS
  The diagnosis of 125 patients by mediastinoscopy accorded with the pathological diagnosis and that of 21 patients was not accorded with the pathology. The rate of definitive diagnosis was 85.6% (125/146). The other 19 cases were not included into the ground because 11 cases were not given definitive diagnosis and 8 cases with lung cancer were not be performed operation although the results of mediastinoscopy were negative. Twenty patients with lung cancer which had metastasis in the mediastium and 7 patients with malignant lymphadenoma avoided exploratory thoracotomy.
  
  
  CONCLUSIONS
  The mediastinoscopy is a effective examinative method to the disease involving the lymph nodes in the mediastinum and the thoracic disease closing on the mediastinum. The mediastinoscopy in appropriate especially to the simple enlargement of lymph node in the mediastinum that is not given definitive diagnosis. The cases with lung cancer accompanied enlargement of lymph node in the mediastinum and that with tumors in the mediastinum may choose the mediastinoscopy.
