Summary

The Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser effectively treats endoluminal lesions in therapeutic bronchoscopy by coagulating or vaporizing tissue. It offers palliative care for malignant tumors and curative potential for benign conditions.

Area of Science:

  • Pulmonology
  • Laser Medicine
  • Endoscopy

Background:

  • Therapeutic bronchoscopy utilizes lasers to manage endoluminal airway lesions.
  • The Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser, transmitted via quartz fibers, has been the primary choice since the early 1980s.

Purpose of the Study:

  • To review the applications and efficacy of the Nd:YAG laser in therapeutic bronchoscopy.
  • To delineate the mechanisms and outcomes for treating both malignant and benign endoluminal lesions.

Main Methods:

  • Application of Nd:YAG laser in coagulation and vaporization modes during rigid bronchoscopy.
  • Mechanical resection techniques employed in conjunction with laser therapy.
  • Combination therapy with radio- and chemotherapy for advanced cases.

Main Results:

  • Nd:YAG laser effectively eliminates endoluminal tumor mass, significantly improving outcomes for tracheal or bronchial asphyxia.
  • Coagulation mode with low energy is typically used for malignant lesions, followed by mechanical resection.
  • The laser demonstrates curative potential for benign lesions.

Conclusions:

  • Nd:YAG laser therapy is a valuable tool in managing endoluminal airway obstructions, particularly for palliative treatment of malignant tumors and curative treatment of benign lesions.
  • Its effectiveness is dependent on lesion type and location; it is less suitable for extrinsic compression and infiltrating lesions.
  • Optimal use involves selecting appropriate power density and potentially combining with other treatment modalities.
