A stent is a metal, tube-like device that can be placed in the esophagus to hold open a narrowed portion so you can eat and drink more easily.
Before the procedure, you will receive anesthesia or medication to help you relax. The stent is inserted in the esophagus with a catheter. When the catheter is removed, the stent stays in place.
In the case of esophageal varices (enlarged veins), a stent can also be placed in the liver to redirect blood flow in the liver away from the varices, relieving blood pressure and reducing the risk of bleeding.
