Abstract:Objective To explore the focus absorption rate and safety of bronchoscopy interventional treatment of elderly patients with pulmonary tuberculosis complicated with bronchial tuberculosis.Methods From January 2018 to January 2020, 60 elderly patients with pulmonary tuberculosis and bronchial tuberculosis were selected. According to different treatment methods, they are divided into anti-tuberculosis chemotherapy drugs combined with bronchoscopy intervention therapy group (ZQ group, n = 32) and anti-tuberculosis chemotherapy drug treatment group (HL group, n = 28). Observe the negative rate of acid-fast bacilli, the improvement of lung disease absorption, the improvement of clinical symptoms, the occurrence of adverse drug reactions, and the clinical efficacy of the two groups of patients.Results After treatment, the negative rate of acid-fast bacilli in the ZQ group (93.75%) was higher than that in the HL group (71.43%). The difference between the groups was statistically significant (χ2 = 5.36, P = 0.021); There were 24 cavities in the ZQ group and 22 cavities in the HL group. After treatment, the closure rate of the ZQ group was 45.83% and the shrinkage rate was 33.33%, which were higher than those of the HL group. The cavity enlargement rate in the HL group was 13.64%, which was higher than that in the ZQ group (4.17%). The total effective rate of patients in the ZQ group (79.17%) was higher than that of the HL group (45.45%). The difference between the groups was statistically significant (χ2 = 5.59, P = 0.018); The significant absorption rate and absorption rate of the lesions in the ZQ group after treatment were higher than those in the HL group, and the difference between the groups was statistically significant (χ2 = 6.37, P = 0.040); The effective rate of granulation treatment in ZQ group was 100.00%, and that in HL group was 75.00%. The difference between the two groups was statistically significant (χ2 = 3.54, P = 0.039); The incidence of adverse reactions in the HL group and ZQ group were 18.75% and 17.86%, the difference between the two groups was not statistically significant (P > 0.05).Conclusion Bronchoscopy interventional treatment of elderly patients with pulmonary tuberculosis and bronchial tuberculosis can significantly increase the rate of negative conversion of acid-fast bacilli and the rate of lesion absorption,and effectively improve the obstruction around the lesion and the condition of bronchial disease, and achieve the ideal clinical effect.
