Endoscopic luminal stenting: Current applications and future perspectives

Table 1 Types of stents

Types of stents	Appropriate indications	Pros	Cons
Uncovered SEMS	Poor survival	Low risk of migration	High risk of tumor ingrowth
	High risk of migration		Difficult removal
	Gastroduodenal obstruction
Partially covered SEMS	Risk of migration		Difficult removal
Fully covered SEMS	Risk of tumor in growth	Safe and easy removal	High risk of migration
	Temporary measure	Low risk of tumor in growth
SEPS	Temporary measure	Safe and easy removal	Complex and stiff stent introducer
	Esophageal stricture	No tumor in growth	High risk of stent failure

SEMS: Self-expanding metal stents; SEPS: Self-expanding plastic stents.
