An esophageal stent may be placed to relieve obstruction caused by a benign or malignant lesion. A stent may also be associated with early or late complications.
Complications that can occur early or late:
(1) chest pain
(2) bleeding
(3) esophageal reflux
(4) stent migration
(5) esophageal perforation
(6) aspiration pneumonia
Late complications include:
(1) stent occlusion/obstruction
(2) tumor ingrowth or overgrowth
(3) anemia (from chronic bleeding)
(4) stricture formation
(5) stent fracture with migration of pieces
