Recent advancement of therapeutic endoscopy in the esophageal benign diseases

Table 3 General differences between stents for benign esophageal disease

Stent type	Advantages	Disadvantages
FCSEMS	No requirement for pre-dilation Recapture is possible	Expensive High migration risk Increased tissue hyperplasia
SEPS	Cheaper than other covered stents Decreased tissue hyperplasia	High migration risk (potentially more than FCSEMS) Require manual loading Require pre-dilation
BDS	No need to remove Less migration risk	Expensive Increased risk of post-procedure pain Require manual loading Require pre-dilation

FCSEMS: Fully covered self-expandable metal stents; SEPS: Self-expandable plastic stents; BDS: Biodegradable stents.
