title: [High frequency electrical knife through fibrobronchoscope in the treatment of tracheal cancer with large airway obstruction].
abstract: From May 1985 to December 1991, high frequency electrical knife (HFEK) through fibrobronchoscope was used to treat the large airway obstruction by tracheal cancers in 11 patients (cystic adenoid carcinoma: 8 squamous cell carcinoma: 2 and undifferentiated small cell carcinoma: 1). Most of the tracheal cancer patients were inoperable because of extensive lesions or poor lung function. Olympus BF B3R or BF 10 Type Fibrobronchoscope, Olympus UES or Olympus PSD-10 high frequent electricity producer with a home-made electrical knife were applied. After 53 times of HFEK treatment of tracheal cancer, all patients showed remarkable improvement in lung function and exertional dyspnea.
  
  
  CONCLUSIONS
  HFEK is valuable in relieving dyspnea in patients with large airway obstruction with tracheal cancer. After endoscopic cautery to release the obstruction, it is necessary to use radiotherapy and chemotherapy for the patients to get better results.
