However the long-term benefits and complications of this management modality in patients with benign and malignant obstructing lesions after SEMS placement are unclear. We performed this cohort study to analyze the outcomes of Ultraflex SEMSs in patients with tracheobronchial diseases. Methods Of 149 patients 72 with benign and 77 with malignant tracheobronchial disease received 211 SEMSs benign 116 malignant 95 and were retrospectively reviewed in a tertiary hospital. Results The baseline characteristics of patients who received SEMS implantation for benign conditions and those who underwent implantation for malignant conditions were significantly different. These characteristics included age mean vs. 58 p gender male 62 vs. 90 p smoking 47 vs. 85 p forced expiratory volume in 1 second mean vs. L s p follow-up days after SEMS implantation median 429 vs. 57 p and use of covered SEMS vs. p . Symptoms improved more after SEMS implantation in patients with benign conditions than in those with malignant conditions vs. p . The overall complication rate after SEMS implantation in patients with benign conditions was higher than that in patients with malignancy vs. p . Successful management of SEMS migration granulation tissue formation and SEMS fracture occurred in 100 and 85 of patients respectively. Conclusions Patients who received SEMS implantation owing to benign
