[Bronchofiberscopy]

New diagnostic modalities have been used in conjunction with endoscopy for early detection of lung cancer. Videoendoscope is routinely used instead of fiberoptic bronchoscope. Fluorescence diagnosis has been proved to be useful in detecting subtle lesions which might be invisible by conventional endoscopy in central airway. Also, a number of small peripheral lesions has increased by the helical CT. CT guided transbronchial lung as well as needle cytology are indicated for definitive diagnosis of such lesions. Endobronchial Ultrasonography is employed to evaluate the depth of cancer invasion of the bronchus and lymph node swelling around the bronchus. It should be helpful in staging of lung cancer and selecting therapy.
