To clarify the role of bronchoscopy for endotracheobronchial tuberculo
sis (EBTB), we performed a prospective study in 45 patients with activ
e pulmonary tuberculosis, in 15 (33%) of whom bronchoscopic findings r
elated to EBTB were seen. The findings were classified into six types:
edematous hyperemic, submucosal nodule, ulcerative (shallow and deep)
, polypoid, cicatrical, and compression type. Each of these types was
related to the healing process and outcome after antituberculosis chem
otherapy. Serial bronchoscopy revealed that lesions less advanced than
the deep ulcerative type responded to chemotherapy; the deep ulcerati
ve and polypoid types progressed to cicatrical bronchostenosis despite
chemotherapy. In the follow-up of patients with lesions of the deep u
lcerative and polypoid types, serial bronchoscopy after chemotherapy i
s recommended; these patients also require adjunctive therapy to preve
nt cicatrical bronchostenosis.
