经支气管镜高频电技术治疗肿瘤性中央气道狭窄的临床价值

目的 探讨经支气管镜高频电技术治疗肿瘤性中央气道狭窄的临床价值。方法 对比分析38例中央气道良性及恶性肿瘤并气道狭窄患者，治疗前后临床表现、不张肺复张、气道再通及肺功能等变化情况。结果 反复咯痰、发热及呼吸困难均于治疗后100%缓解、消失，刺激性咳嗽94.4%改善、咯血87.5%改善，不张肺的肺复张率92%。治疗结束时中央气道狭窄再通即时疗效无论良性、恶性组疗效均为100%，治疗结束后3月中央气道狭窄再通总有效率94.7%。气促评分、肺功能（肺通气功能、换气功能及气道阻力）改善情况，治疗前后比较差异均具有统计学意义（P<0.001）。并发症少，复发率低。结论 经支气管镜高频电技术治疗肿瘤性中央气道狭窄是一项安全、有效的治疗手段，比较适合我国国情。

Clinical Value of Hypercator through Flexible Bronchoscope in Management of Central Airway Stenosis Induced by Tumors

Objective To explore clinical value of the hypercator through flexible fiberoptic bronchoscope in management of the central tracheobronchial stenosis resulted by tumors. Methods Thirty eight tumor (malignant and benign) cases with the central tracheobronchial stenosis were treated with the hypercator through flexible fiberoptic bronchoscope. Improvement of clinical features, atelectasis, airway diameters and pulmonary function were evaluated after treatment. ResultsThrough treatment, the clinical symptoms such as frequent expectoration, fever and dyspnea were released completely, and irritable cough (94.4%), hemoptysis (87.5%) were greatly improved. The recovery rate of atelectasis was 92%. The unobstructed,central airway was observed either malignant or benign tumors were 100% at the end of treatment, and still 94.7% 3 monthes later. There were significant differences in the dyspnea index and pulmonary function between before and after treatment(P<0.001). Seldom complications and low relapse rate were found in these patients. Conclusion The hypercator through flexible fiberoptic bronchoscope was a simple, effective and safe method to treat the central tracheobronchial stenosis induced by tumors, and widely utilized in our country.
