经气管镜电圈套器联合CO(2)冷冻及氩等离子体凝固等治疗77例气道内肿瘤和息肉

BACKGROUND AND OBJECTIVE: To observe the clinical effects and safety of endobronchial electrocautery snare combined with CO(2) cryosurgery for the treatment of tracheobronchial obstructive lesions. MATERIALS AND 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 CO(2) 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. CONCLUSION: Endobronchial electrocautery snare is an effective and safe approach for tracheobronchial obstructions with few complications.
