Removal of self-expandable metallic stents: is it possible?

Self-expandable metallic stents (SEMS) have become an important component of the management of central airway disease. These stents are not, however, without problems and stent-related complications (SRCs) can be more formidable to treat than the original indication for SEMS placement. As use of SEMS has increased, the number of patients returning to hospital for management of SRCs has similarly risen. A small group of these patients will have, as their only therapeutic option, stent removal Thus far limited experience exists with late stent removal. Stent extraction is difficult and requires expertise in a variety of techniques. A multidisciplinary approach to both SEMS placement and extraction is strongly advocated.
