title: [Nasal route flexible broncho-fiberscopy, as a tool of mass examination for hilar type lung cancer (author's transl)].
abstract: Early detection of lung cancer is mandatory problem in the medical field. Although, chest x-p examination is a strong armament for detection of peripheral type of lung cancer, the method has rather weak point in detection of hilar type of bronchogenic carcinoma. Bronchoscopy is essential method for diagnosis of bronchial changes of this disease. It is, however, not popular method yet, because of its troublesome technique, such as insertion of tracheal tube, eventhough new instrument of flexible fiber bronchoscopy makes us very much easy way to use, compared with old-fashioned rigid bronchoscopy. For mass examination of high risk group of bronchogenic carcinoma (chromate workers), we are using nasal route flexible fiberbronchoscopy. Comparing of this method with previously used trans-oral route, both easiness of the technique on doctor's side, and comfort during the examination on the patients's side revealed favorable results for nasal method.
