Clinical analysis of electrocoagulation and argon plasma coagulation via bronchovideoscope in the treatment of tracheobronchial stenosis

[Objective] To evaluate the effectiveness of high-frequency electrocoagulation and argon plasma coagulation(APC) via bronchovideoscope in the treatment of tracheobronchial stenosis.[Methods] 21 patients with tracheobronchial stenosis were treated with APC equipment via bronchovideoscope,including 17 cases of lung cancer,4 cases of foreign body in trachea or inflammatory granuloma.The location of the airway lesions,the degree of obstruction,dyspnea index,and complications were evaluated.[Results] Full effectiveness was achieved in 9 cases(42.8%),partial in 8 cases(38.1%),mild in 3 cases(14.2%) and none in 1 case(4.7%),The overall effective rate was 95.2%.There were no serious complications.[Conclusion] High-frequency electrocoagulation and APC via bronchovideoscope is an effective and safe method to treat tracheobronchial stenosis,which can significant relieve clinical symptoms and improve quality of life.
