Summary

Interventional bronchoscopy effectively manages tuberculosis-related tracheobronchial stenosis, providing immediate symptom relief. While beneficial, repeated procedures may be necessary for sustained improvement in airway diameter.

Area of Science:

  • Pulmonology
  • Interventional Pulmonology
  • Respiratory Medicine

Background:

  • Tuberculosis (TB) can cause symptomatic tracheobronchial stenosis, leading to significant respiratory compromise.
  • Management of such stenosis often requires advanced techniques to restore airway patency.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of interventional bronchoscopic techniques in managing tracheobronchial stenosis secondary to tuberculosis.
  • To assess the immediate and long-term symptomatic relief and airway diameter changes following these procedures.

Main Methods:

  • A cohort of 21 patients with symptomatic tracheobronchial stenosis due to TB underwent rigid bronchoscopy.
  • Interventional techniques included mechanical/balloon dilatation, Nd-YAG laser ablation, and Dumon stent placement under general anesthesia.

  • Airway luminal diameter was measured pre- and post-intervention.

    • Main Results:

    • Significant increases in luminal diameter were observed: trachea from 4.5 mm to 11.9 mm, and mainstem bronchi from 2.6 mm to 8.3 mm.
    • All patients experienced immediate symptomatic relief post-procedure.
    • 52% of patients remained asymptomatic at the end of the study period, with two patients weaned off mechanical ventilation.

    Conclusions:

    • Interventional bronchoscopic techniques are effective in providing immediate symptomatic relief for tracheobronchial stenosis caused by tuberculosis.
    • While initial relief is significant, repeated interventions may be required for sustained airway patency.
    • These endoscopic methods represent a valuable therapeutic option for this challenging condition.
