Abstract

Introduction and objective Silicon and metallic are two types of stents in use. In this study, we compared complications and long-term survival among patients who received silicon or fully covered, bifurcated self-expandable metallic stents (SEMS) for a malignant tracheobronchial obstruction and/or tracheo/bronchial oesophageal fistulas. Methods Patients in whom Y-shaped stents were used from January 2013 to June 2017 in our interventional pulmonology unit were evaluated retrospectively from patient files. Results Of the 47 patients, 30 (23 males, 76.7%) were in the silicon stent group and 17 (14 males, 82.4%) were in the covered SEMS group. No differences between the groups were detected in ECOG status, pathological properties of the disease, radiotherapy or chemotherapy history before the procedure, symptoms at presentation, or comorbidities. The most common symptom was dyspnoea (96.7% and 100%), and the most common comorbidity was chronic obstructive pulmonary disease (26.7% and 23.5%). A total of 20 complications (42.6%) were seen, with no significant difference between the groups (silicon, 40%; SEMS, 47.1%; P = . 62). Mean survival was 164.51 ± 38.83 days for the silicon stent group and 254.45 ± 103.32 days for the SEMS group (P = .588). No differences were observed in 30-, 90- or 180-day mortality between the two groups (P = .966, .846 and .534, respectively). Conclusions No significant differences in symptom palliation, insertion safety, complication rate or survival were detected between the two types of stent.
