目的：探讨纤维支气管镜导管介入对复治菌阳肺结核的治疗效果。方法：对复治菌阳肺结核１７０例随机分为治疗组８４例及对照组８６例，两组均给于常规化疗，治疗组强化期经纤维支气管镜导管介入病灶内注入抗痨药，对比观察两组疗效。结果：治疗组痰菌阴转率９０．２％，病灶显效率８６．６％，空洞闭合率３２．９％，均显著高于对照组的６０．５％、５８．０％、１３．９％（Ｐ＜０．０１）。结论：纤维支气管镜导管介入病灶内注药加化疗对复治菌阳肺结核的疗效优于单纯化疗。
Objective: To investigate the therapeutic effect of bronchoscope catheterization on retreatment of positive pulmonary tuberculosis. Methods: 170 cases of retreatment of positive pulmonary tuberculosis were randomly divided into treatment group (n = 84) and control group (n = 86). Both groups were given conventional chemotherapy. The treatment group was given anti-tuberculosis drug through bronchofocalconeal catheter Two groups of curative effect. Results: The sputum negative conversion rate was 90.2%, the effective rate of lesions was 86.6% and the void closure rate was 32.9% in the treatment group, which were significantly higher than 60.5%, 58.0% and 13.9 of the control group % (P <0.01). Conclusion: The therapeutic effect of fibrobronchial catheter interventional lesion injection plus chemotherapy on retreatment of positive pulmonary tuberculosis is better than that of chemotherapy alone.
