Summary

The neodymium:yttrium-aluminum-garnet (Nd:YAG) laser enables precise pulmonary lesion removal, preserving lung tissue. This technique is effective for patients with compromised lung function or deep-seated tumors.

Area of Science:

  • Thoracic Surgery
  • Surgical Oncology
  • Laser Medicine

Background:

  • Pulmonary lesions pose challenges for complete resection, especially in patients with impaired lung function.
  • Traditional surgical methods may lead to significant loss of lung parenchyma.
  • Deep-seated lesions often require extensive resections like lobectomy.

Purpose of the Study:

  • To evaluate the efficacy and safety of neodymium:yttrium-aluminum-garnet (Nd:YAG) laser excision for pulmonary lesions.
  • To assess the Nd:YAG laser's utility in patients with compromised pulmonary function.
  • To present the operative technique for Nd:YAG laser resection of lung lesions.

Main Methods:

  • Local excision of 32 pulmonary lesions in 26 patients using the Nd:YAG laser.

  • Limited thoracotomy was employed in 23 patients.
  • Resected lesions included primary malignant tumors, metastatic lesions, and benign tumors.

    • Main Results:

    • The Nd:YAG laser allowed precise excision with minimal lung parenchyma loss.
    • Mean operating time was 80 minutes, with laser resection time averaging 15 minutes.
    • No significant difference in pulmonary function was observed post-surgery, and no local recurrences were reported at 2-year follow-up.

    Conclusions:

    • The Nd:YAG laser is a valuable tool for pulmonary lesion resection, particularly for patients with marginal lung function.
    • It facilitates precise removal of deep-seated lesions, potentially avoiding lobectomy.
    • The technique demonstrates safety and efficacy with favorable long-term outcomes.
