title: [Diagnostic role of fiberoptic bronchoscopy for mycobacterial diseases].
abstract: From 1981 to 1991, 5,572 patients underwent bronchoscopic examination, in this series 3,754 patient's samples were sent for determination of mycobacterial isolation. In the 506 samples, mycobacterial bacilli were detected with smear or culture. In the low tuberculous incidence area like northern part of America, many reporters supported the opinion that routine bronchial aspirate detection for tuberculosis was not cost-effective. Inversely, in the high tuberculous incidence area like Hong Kong, M. lp et al. claimed the usefulness of routine bronchial aspirate examination for mycobacterial bacilli. Japan was regarded as moderate tuberculous incidence area. We review a ten-year experience with fiberoptic bronchoscopy for mycobacterial isolation. Our results suggest that in an area with a moderate prevalence of tuberculosis, bronchoscopic examination for mycobacterial disease is useful in the selected hospitals for the selected cases. In Japan, the smear positive prevalence has been on the increase from 1982. We estimate that the Japanese popularization of fiberoptic bronchoscopy may influence a part of the Japanese epidemic statistical analysis of mycobacteriosis.
