Value Of Bronchoscopy Interventional Therapy In Benign And Malignant Airway Stenosis

Objective(s):To explore the value of bronchoscopic interventional therapy in the benign and malignant airway stenosis.Methods:114cases patients of airway atenosis were retrospectively analyzed after bronchoscopic inerventional therapy in our hospital from April 2015 to November 2018,of which 8 cases were benign and 12 cases were malignant.The causes include benign and malignant tumors in the airway,tuberculosis,granulomatous lesions,foreign bodies,etc.,Carrying out treatments such as freezing,electric knife,argon knife,balloon expansion,etc.To evaluate the effectiveness and safety of the treatment.Results:Seventy-four patients with benign airway stenosis were compared with airway stenosis before and after treatment,t=26.433,P=0.000,the difference was statistically significant,(2.51±0.99)before treatment and mMRC(1.70±1.05)after treatment.The difference was statistically significant(P<0.05).Forty patients with malignant airway stenosis were compared with airway stenosis before and after treatment,t=8.062,P=0.000,the difference was statistically significant;mMRC was(2.75±0.55),and after treatment mMRC(2.50±0.61),the difference was statistically significant(P<0.05).The two groups were effective,and the benign group was better than the malignant group.and no serious complications occurred during the operation.Conclusion(s):The efficacy of interventional treatment of benign and malignant airway stenosis by electron bronchoscopy is significant,and the safety is high.The therapeutic effect of benign airway stenosis is significantly greater than malignant.It provides a safe and effective option for patients with airway stenosis who have no chance of surgery or who are unwilling to undergo surgical thoracotomy.
