Fibreoptic bronchoscopy today: a review of 255 cases

An analysis of 255 fibreoptic bronchoscopies showed that the major indication for bronchoscopy was suspected bronchial carcinoma (93% of cases). Of the 183 patients finally shown to have bronchial carcinoma 83% had abnormal bronchoscopy findings and 65% had bronchial biopsy specimens diagnostic of malignancy. These figures were superior to those obtainable with rigid bronchoscopy, particularly with upper lobe and peripheral tumours. Brush biopsy and bronchography were useful supplementary techniques. Sputum cytology gave poorer results than fibreoptic bronchoscopy, but enabled diagnosis in some otherwise undiagnosed cases. The complication rate was low and the claim of this new technique to be the investigation of choice in bronchial carcinoma seemed to be justified in clinical practice.
