Background: To observe the clinical effects and safety of endobronchial electrocautery snare combined with CO₂ cryosurgery for the treatment of tracheobronchial obstructive lesions.
Methods: 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).
Results: 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.
Conclusions: Endobronchial electrocautery snare is an effective and safe approach for tracheobronchial obstructions with few complications.
背景与目的 采用电圈套器联合CO2冷冻等治疗气道内大的肿瘤或息肉，探讨其疗效和安全性。方法 77例大气道内肿瘤或息肉患者（恶性肿瘤70例，良性病变7例）在硬质镜引导下，结合电子支气管镜，利用电圈套器联合CO2冷冻等进行治疗。结果 77例患者进行电圈套器治疗85例次。病变位于右侧支气管42.9%，主气管38.3%和左侧支气管21.4%，少数位于亚段支气管开口。恶性肿瘤混合型占89.7%，单纯管内型仅占10.3%。圈套器治疗前气道内堵塞约4/5，术后约1/5；KPS评分和气促指数治疗后均有明显改善。未发生大出血、穿孔等并发症。结论 电圈套器联合CO2冷冻等治疗气道内肿瘤或息肉，安全、有效、快速。
