Three stent place
When the esophagus becomes narrowed or blocked (most commonly due to cancer), doctors insert a self-expanding metal stent (SEMS) through an endoscope (a flexible camera passed through the mouth).
The stent expands on its own and opens the blocked area, allowing food and liquids to pass more easily.
