Objective To analyze the clinical efficacy of high-frequency electric knife and argon plasma coagulation combined with cryotherapy in the treatment of malignant airway diseases. Methods The subjects of this study were 40 patients with malignant stenosis of the trachea and bronchi, selected from November 2022 to May 2024. The patients were divided into two groups using a random number table method. The control group received high-frequency electric knife treatment, while the observation group received argon plasma coagulation and cryotherapy, with 20 patients in each group. Evaluate the clinical efficacy and FEV1 indicators of lung function before and after treatment for two groups. Results Compared with the conventional group, the experimental group had a significantly higher treatment effectiveness rate (P<0.05), and after treatment, the FEV1 index of lung function in the experimental group was better than that in the conventional group (P<0.05). Conclusion The clinical efficacy of argon plasma coagulation combined with cryotherapy in the treatment of patients with malignant airway stenosis is definite, and it can more effectively improve patients' lung function, which is worthy of clinical promotion and application.
