Procedure
A stent is a small flexible tube placed endoscopically to relieve obstruction caused by tumour, stricture, or external compression. Restores swallowing, drainage, or bowel transit without surgery.
Stents are deployed through an endoscope under fluoroscopic guidance. They expand to hold open the narrowed segment, allowing normal flow.
Different stents are used for the food pipe, bile duct, duodenum, and colon, each chosen for the specific anatomy and indication.
Performed under sedation or general anaesthesia depending on the site.
A guide wire is passed across the obstruction. The stent is then deployed and gradually expands to its full size.
Stent migration, blockage, and over-grown tissue at the ends are recognised long-term issues and may require re-intervention.
Common questions
How long does a stent last?
Plastic stents need replacement every 3 months. Metal stents may last a year or longer.
