    Laser fragmentation successfully removed a large broncholith in an elderly patient, avoiding surgery. This YAG laser technique offers a minimally invasive option for impacted bronchial stones.

    Area of Science:

    • Pulmonology
    • Interventional Bronchoscopy
    • Medical Technology

    Background:

    • Broncholiths, calcified masses in the airway, can cause significant respiratory obstruction.
    • Traditional removal methods like flexible and rigid bronchoscopy may fail for large or impacted broncholiths.

    Observation:

    • An 85-year-old female patient presented with an impacted broncholith in the intermediate bronchus.
    • The broncholith was too large and impacted for removal via conventional flexible or rigid bronchoscopy.

    Findings:

    • Neodymium-doped Yttrium Aluminum Garnet (YAG) laser fragmentation was employed to break down the broncholith.
    • The fragmented broncholith pieces were successfully removed through a bronchoscope.
    • Chemical composition and morphology of the broncholith were analyzed.

    Implications:

    • Laser lithotripsy provides a viable, minimally invasive alternative to thoracotomy for impacted broncholiths.
    • This approach can significantly reduce patient morbidity, especially in elderly or high-risk individuals.
    • Further research into laser applications for airway stone management is warranted.
