Argon-laser ablation is a new method of airways recanalization for tumoral stenosis

Abstract

AIM: To develop the new method of laser recanalization of airways for tumoral stenosis., MATERIAL AND METHODS: It is proposed to conduct laser effect in the gas environment that does not support combustion (argon). Also the device for these AIM: is suggested. The method is called argon-laser ablation (ALA). A comparison of ALA and conventional high-energy laser exposure (LPD) was performed., RESULTS: ALA and LPD were used in 46 patients and 17 patients with non-small cell lung cancer. The duration of endobronchial operations and incidence of complications were significantly higher in group 2. The incidence of complete remission was significantly higher in group 1., CONCLUSION: Endobronchial argon-laser ablation of tracheal and bronchial tumors removes exophytic tumoral component in more favorable conditions compared with conventional high-energy laser exposure. Also it significantly increases an efficiency and reduces the frequency of complications.
