To the Editor.—
The advent of bronchofiberscopy has changed the whole concept of bronchoscopy as a diagnostic and therapeutic tool. Bronchoscopy, thanks to the use of fiberoptics, is now within the capability of pulmonary clinicians at the bedside, in the x-ray department, or in the physician's office.The fiberoptic bronchoscope permits the area of the tracheobronchial tree under direct scrutiny to be extended from the merely central to the segmental and subsegmental airways. The instrument also allows the operator to pass a biopsy forceps or a bronchial brush beyond its visual range and thus obtain tissue intrabronchially or transbronchially.1Pleuroscopy may again become an adjunct to the diagnosis of chest diseases. Gwin et al2 employed the fiberoptic bronchoscope to carry out pleuroscopy in nine patients with undiagnosed pleural effusions and succeeded in examining the entire pleural space "with minimal technical difficulty" in the absence of pleural adhesions.
