目的观察纤支镜微波治疗气道腔内病变的疗效。方法采用经纤支镜微波组织热凝疗法治疗气道腔内病变,观察治疗后狭窄管腔的改变、呼吸困难指数和肺功能改善情况及肺不张的变化。结果7例患者经微波治疗后管腔狭窄的程度均有不同程度的改善,呼吸困难指数和肺功能也有明显改善,2例合并肺不张的患者治疗后肺复张。结论经纤支镜微波治疗气道腔内病变疗效显著,安全实用,副作用小,值得推广。 Objective To observe the curative effect of bronchofiberscopy in the treatment of airway lesions. Methods The bronchial tissue thermocoagulation was performed with fiberoptic bronchoscopy for the treatment of airway lesions. Changes of stenosis, changes in dyspnea index, pulmonary function and atelectasis were observed. Results The degree of stenosis was improved to some degree in 7 patients after microwave treatment. The index of dyspnea and pulmonary function were also improved obviously. Two patients with atelectasis were recruited after treatment. Conclusion The therapeutic effect of bronchofibroscopy in the treatment of airway lesions is significant, safe and practical, and has few side effects. It is worth to be popularized.
