Abstract: Objective To study the effects and advantages of the treatment of lymph node fistula type bronchial tuberculosis by bronchoscopy. Methods A total of 64 patients with lymph node fistula bronchial tuberculosis who received treatment in our hospital from March 2017 to March 2018 were selected. The control group was treated with conventional chemotherapy for tuberculosis, and the experimental group was treated with bronchoscopy. Sputum conversion, lesion absorption, clinical effect and adverse reactions were compared between the two groups. Results After 1 month (59.38%), 2 months (81.25%) and 3 months (93.75%), the proportion of sputum bacteria becoming to negative in the experimental group was significantly higher than that in the control group (25.00%, 34.38%, 46.88%, P<0.05). There was no significant differences (P>0.05) in the proportion of lesion absorption (21.88%, 18.75%) between the 2 groups at 1 month after treatment (65.63%) and 3 months after treatment (96.88%). The rate of lesion absorption in the experimental group was significantly higher than that in the control group (27.13%, 34.38%, P<0.05).The total effective rate of clinical treatment of lymph node fistula bronchial tuberculosis in the experimental group was significantly higher than that of the reference group, with significant difference (93.75%, 59.38%, P<0.05). There was no significant difference in the incidence of adverse reactions (12.50%, 15.63%) after treatment of lymph node fistula bronchial tuberculosis between the 2 groups (P<0.05). Conclusion The treatment with lymph node fistula type bronchial tuberculosis can effectively improve the clinical effect of chemotherapy, improve the sputum negative rate of the patients, and promote the full absorption of the lesions of the patients. In addition, this treatment has fewer adverse reactions and higher safety, which should be promoted clinically.
