目的　探讨纤支镜微波治疗良、恶性肿瘤临床效果及方法学研究。方法　经纤支镜活检孔道插入微波同轴导线 ,将导线尖型前端刺入新生物内 ,时间 6～ 8s,拔出微波导线清洗尖端坏死物 ,根据病人的耐受性 ,可反复插入微波同轴导线 3～ 10次。间隔 3～ 14d重复治疗。结果　大部分肿瘤消失 ,临床症状缓解 ,胸片及胸部CT示肺不张或阻塞性肺炎消失 ,追踪观察 1～ 10年未见复发。结论　①纤支镜微波治疗支气管肿瘤疗效确切 ,且痛苦小 ,安全性大 ,可替代手术治疗。②此方法对良性肿瘤效果佳 ,恶性肿瘤稍差。③治疗间隔时间不宜过短 ,以 10～ 14d为佳 Objective To investigate the clinical effect and methodological study of bronchofiberscopy in the treatment of benign and malignant tumors. Methods The microwave coaxial cable was inserted into the biopsy canal via fiberoptic biopsy. The tip of the lead was punctured into the new organism for 6 ~ 8 seconds. The microwave catheter was pulled out to remove the tip necrosis. According to the patient’s tolerance, Axis 3 to 10 times. Interval 3 ~ 14d repeated treatment. The results of most of the tumor disappeared, clinical symptoms, chest X-ray and chest CT showed atelectasis or obstructive pneumonia disappeared, follow-up observation of 1 to 10 years no recurrence. Conclusion ① Bronchoscopy with bronchoscope is effective in treating bronchial neoplasm with little pain and safety, which can replace surgical treatment. ② This method is good for benign tumors, malignant tumors slightly worse. ③ treatment interval should not be too short, preferably 10 ~ 14d
