ABSTRACT:
Objectives: To present the
complications of Ultraflex Self-Expandable Metallic Stents (SEMSs) applied in patients with benign tracheobronchial diseases. Methods: Eighty patients received 124 SEMSs were retrospectively reviewed
in a tertiary hospital. Results: The baseline
characteristics of patients received SEMS implantation including age
(mean + standard deviation: 62.5 + 14.8 years), gender (male, 60.5%), smoking
(46.8%), forced expiratory volume in first one second (FEV1) (mean + standard
deviation, 0.92 +0.41 L/s),
follow-up days after SEMS implantation (median (interquartile range); 457 (131 -
897)) and covered SEMS (33.9%) were listed. Symptoms improved after SEMS
implantation among 95 patients (76.6%). Time to complications developed was 236
(median; interquartile range, 59 - 672) days. The overall complication rate was
41.9% after SEMS implantation. The complications included SEMS migration
(6.5%), granuloma (19.3%) and SEMS fracture (16.1%). Successful management
rates of SEMS migration, granuloma and SEMS fracture were up to 100%, 83.3%,
and 85% respectively. Conclusions: Patients received SEMS implantation due to
benign conditions had poor lung function and were old. The complication rate in
patients with benign conditions was high after longer follow-up period,
however, successful management achieved in most patients with complications.
