Summary

Bronchoscopic removal of airway calcifications, known as broncholiths, is a safe and effective treatment for broncholithiasis. This procedure successfully removed free and eroding broncholiths with minimal complications.

Area of Science:

  • Pulmonology
  • Interventional Pulmonology
  • Respiratory Medicine

Background:

  • Broncholithiasis, characterized by calcified material in the airway, is typically diagnosed via bronchoscopy.
  • The therapeutic efficacy of bronchoscopy for broncholithiasis has not been extensively studied in large patient cohorts.

Purpose of the Study:

  • To evaluate the therapeutic role and safety of bronchoscopy in the management of broncholithiasis.
  • To assess the success rates of broncholith removal using both flexible and rigid bronchoscopes.

Main Methods:

  • Retrospective review of clinical data from 95 patients diagnosed with broncholithiasis between 1954 and 1994.
  • Analysis of 127 broncholiths identified during bronchoscopy, with a focus on attempted endoscopic removal in 48 patients.

  • Comparison of removal success rates based on broncholith type (free vs. partly eroding) and bronchoscope type (flexible vs. rigid).

    • Main Results:

    • Bronchoscopic removal was attempted for 71 broncholiths (56%), with 48% of partly eroding and 100% of free broncholiths successfully extracted.
    • Rigid bronchoscopy demonstrated higher success rates (67%) for removing partly eroding broncholiths compared to flexible bronchoscopy (30%).
    • Complications were infrequent (4%), including hemorrhage and acute dyspnea, primarily associated with partly eroding broncholiths.

    Conclusions:

    • Flexible and/or rigid bronchoscopic extraction of broncholiths is a safe and effective therapeutic option.
    • Endoscopic removal should be considered for both free and partly eroding broncholiths within the tracheobronchial tree.
    • The findings support the expanded role of bronchoscopy beyond diagnostics in managing broncholithiasis.
