A new interventional therapeutic technique for malignant tracheobronchial stricture with expandable metallic stents

Objective To introduce a new therapeutic technique of tracheal stent intubation and to evaluate the treatment effect of self expandable metallic stents in tracheal malignant stricture Methods 16 cases(male 10, female 6) were placed by intraluminal stents intubation There were 8 cases with tracheal carcinoma, 6 cases with upper segment esophageal carcinoma encroaching upon trachea and 2 cases with laryngeal carcinoma The main clinical symptoms were dyspnea, stridor and 2 cases with esophagotracheal fistula complaining of choking The instruments used were as following: 14 F stent delivery sheath with radiopaque mark at the distal portion, stent pusher, guide wire, catheter and so on Z stent and NiTi alloy stent were used In all cases, peroral laryngeal intubation of the stents was performed under fluoroscopic guidance Results All stents were successfully placed without technical failure The symptoms of dyspnea, stridor and choke were immediately relieved after finishing the stent placement procedure Conclusions Tracheal stenting is a safe, and efficient method with immediate relief of symptoms and improvement of quality of life in patients suffering from malignant tracheobronchial stricture
