    Summary
    This summary is machine-generated.

    Endobronchial tuberculosis (TB) affects older men and often presents with non-specific symptoms. Post-treatment, most patients develop airway narrowing (bronchostenosis), which is difficult to detect non-invasively.

    Area of Science:

    • Pulmonology
    • Infectious Diseases
    • Endoscopic Procedures

    Background:

    • Endobronchial tuberculosis (TB) is a significant pulmonary infection.
    • Traditional understanding of endobronchial TB demographics and clinical presentation may be outdated.
    • Accurate diagnosis is crucial to differentiate from other conditions like bronchogenic carcinoma.

    Purpose of the Study:

    • To analyze the clinical characteristics of endobronchial TB in a contemporary cohort.
    • To evaluate the diagnostic accuracy of various methods.
    • To assess the long-term sequelae, specifically bronchostenosis, after chemotherapy.

    Main Methods:

    • Retrospective analysis of 20 patients with endobronchial TB.
    • Diagnosis confirmed via fiberoptic bronchoscopy and bronchial biopsy.

  • Post-treatment follow-up including bronchoscopy and bronchography for 12 patients.

    • Main Results:

    • The disease predominantly affects older males, differing from historical data.
    • Fever and wheezing were infrequent; sputum smears for acid-fast bacilli (AFB) were often negative (85%).
    • Bronchostenosis was a common complication (11/12 patients) post-chemotherapy, with insensitive noninvasive detection.

    Conclusions:

    • Contemporary endobronchial TB presents differently, posing diagnostic challenges.
    • Bronchostenosis is a frequent long-term complication requiring invasive assessment.
    • Steroid therapy did not appear to alter the outcome of tuberculous endobronchitis.
