[Endobronchial laser therapy of post-tuberculosis bronchial fibrous stenosis]

The results of endobronchial treatment of 9 patients with post-tuberculous fibrous stenoses of large bronchi by using neodymium-YAG laser are presented. After recanalization of fibrous stenoses the patients were given antioxidants (7.5% sodium thiosulfate solution, 0.5 ml, as endobronchial infusions in combination with oral or intramuscular alpha-tocopherol, 600 mg, for a month) in combination with endobronchial phototherapy with helium-neon laser radiation. This therapy improved the patients' general condition, pulmonary functional parameters, normalized lipid peroxidation and enhanced epithelial regeneration in the bronchial mucosa, thus providing a steady-state dilatation of the airways lumen by more than twice than that in stenosis.
