Abstract
By using ridgid telescope and flexible fiber bronchoscope, the intensity of visual field became peripheler in the lung than that obtained by the previous ones.
In the present work, we are going to report briefly on the relationship between bronchoscopic findings and how it has been consisted by the bronchial spread of lung cancer, pathologically.
The direct vision and indirect vision (stenotic types) of tumor invasion were divided into following
4 types respectively according to bronchial invasion of the carcinoma.
Direct vision.
I.localized polypoid type
II.polypoid process extending proximally
III. direct invasion of parabronchial, wall and lymphatics
IV. invasion of epithelium from the metastatic lymphnode Indirect vision
I.narrowing of the bronchus due to expansive growth of the tumor
II.narrowing of the bronchus due to the subepithelial lymphnode metastasis
III., IV. transposition of the bronchus due to expansive growth of the tumor
These findings were examined histologically and comparatively.
Recognition for spread of carcinoma of the bronchus should be performed always in combination with above information and X-Ray or cytological diagnosis.
In this way, is more adequate surgical suggestion and other suitable therapoetic treatment obtained.
