Transcatheter bronchial brush and forceps biopsies. Histologic evaluation.
The histologic findings in transcatheter brush and forceps biopsies from 472 cases over a six-year period are evaluated. Diagnostic accuracy based on histologic findings was 38% and based on cytologic findings was 70%. When the two methods of examination were used, however, the overall accuracy was improved to 76%. In Hodgkin's disease and some inflammatory processes histologic examination is essential for the diagnosis. The transcatheter biopsies under fluoroscopic control are especially useful for securing tissues from the peripherally located lesions. When possible, examination of tissue obtained by transcatheter as well as forceps biopsies is encouraged.
