RESULTS: (1) A total of 6 males, 9 females, aged 18-70 y (35±14) of benign airway stenosis were included in the analysis. A total of 19 tracheobronchial stents placements were conducted, including 11 covered metallic stents (CMS) and 8 uncovered metallic stents (UCMS). The 19 tracheobronchial were removed with an median time 2.4 months (inter-quartile range, 0.6 -3.6 months), and 1 of which was indwelt more than 10 years. (2) Of the 8 UCMS, 7 embedded with hyperplastic granulation tissue and resultant airway stenosis, 2 with stent fracture and 1 with stent displacement were observed before stents retrieval. Of the 11 CMS, 5 embedded with hyperplastic granulation tissue and resultant airway stenosis, 1 with stent fracture and 3 with stent displacement were observed. (3) 19 stents were all removed successfully under local anesthesia combined with intravenous drugs based anesthesia. In all cases, 4 patients were suffered from post-removal complications including mucosal tear (n=2, 10.5%), moderate hemorrhage (n=1, 5.3%), and bronchial fistula (n=1,5.3%). No death occurred during the procedure.
