Abstract：Objective: To analyze the curative effect of interventional cryotherapy for bronchial tuberculosis patients by fiberoptic bronchoscope. Methods: Sixty-eight patients with bronchial tuberculosis admitted to our hospital from October 2016 to October 2017 were randomly divided into control group and experimental group. Both groups were given routine anti-tuberculosis chemotherapy, while the experimental group was given fiberoptic bronchoscopic interventional cryotherapy on this basis. The sputum negative rate, chest CT changes and changes under bronchoscope were compared between the two groups. Results: There were 30 sputum positive patients, 4 sputum negative patients, 28 sputum positive patients and 6 sputum negative patients in the control group before treatment. After treatment, there were 14 sputum-positive patients, 20 sputum-negative patients, 9 sputum-positive patients and 25 sputum-negative patients in the control group, respectively. After treatment, the sputum negative rate of the experimental group was 89.29%, which was significantly higher than that of the control group 66.67% (χ2= 8.934, P<0.05). The total effective rate of the experimental group was 91.18%, which was significantly higher than that of the control group (χ2= 9.273, P<0.05). The total effective rate of fiberoptic bronchoscopy in the experimental group was 94.12%, which was significantly higher than 70.59% in the control group (χ2= 10.029, P<0.05). Conclusion: Transbronchoscopic cryotherapy combined with systemic chemotherapy can effectively improve the sputum negative rate of patients with bronchial tuberculosis, greatly improve the clinical efficacy of patients. It is worthy of clinical application.
