To observe the clinical effects and safety of endobronchial electrocautery snare combined with CO₂ cryosurgery for the treatment of tracheobronchial obstructive lesions.
Seventy-seven patients with airway tumor or granuloma were retrospectively reviewed, including 70 malignant airway obstruction and 7 benign airway lesions, for the treatment of endobronchial electrocautery snare plus CO₂ cryosurgery and argon plasma coagulation (APC).
Eighty-five endobronchial snares were performed in 77 cases. 42.9% of the obstructive lesions were located in right bronchial orifice, 38.3% in main trachea 21.4% in left bronchial orifice. 89.7% of the malignant tumor was mixed type of lesions (endobronchial plus bronchial or external bronchial), only 10.3% was endobronchial. Obstructive stenosis was significant relieved after snare (80% before vs 20% after, P<0.01) in all patients. Karnofsky Performance Status (KPS) and shortbreath score were obviously improved after snare. There was no severe complications related to the procedures.
Endobronchial electrocautery snare is an effective and safe approach for tracheobronchial obstructions with few complications.
观察支气管内电圈套联合CO₂冷冻治疗气管支气管阻塞性病变的临床疗效及安全性。
回顾性分析77例气道肿瘤或肉芽肿患者，其中70例为恶性气道阻塞，7例为良性气道病变，采用支气管内电圈套联合CO₂冷冻及氩等离子体凝固（APC）治疗。
77例患者共进行85次支气管内圈套治疗。42.9%的阻塞性病变位于右支气管口，38.3%位于主气管，21.4%位于左支气管口。89.7%的恶性肿瘤为混合型病变（支气管内加支气管或支气管外），仅10.3%为支气管内型。所有患者圈套治疗后阻塞性狭窄明显缓解（术前80% vs术后20%，P<0.01）。圈套治疗后卡氏功能状态评分（KPS）及气短评分明显改善。未出现与手术相关的严重并发症。
支气管内电圈套是治疗气管支气管阻塞的一种有效、安全的方法，并发症少。
