Laser bronchoscopy--current status.

The majority of patients with lung cancer have advanced disease with severe endobronchial symptoms such as cough, dyspnea, and hemoptysis for which palliation is required. Laser resection of endobronchial lesions located in the trachea, mainstem or proximal lower lobe bronchi provides significant and rapid improvement in the patient's symptoms. Neodymium:yttrium-aluminium-garnet (Nd:YAG) laser is gaining popularity due to efficient photocoagulation, good penetration and excellent hemostasis. Complications are rare and can be minimized by following standardized techniques and safety guidelines. Laser resection is equally effective with the rigid and flexible bronchoscope. The future may see combinations of laser with other palliative modalities to improve the chances of a symptom-free life for lung cancer patients.
