Esophageal stenting is a medical procedure that involves the placement of a stent (a small, expandable metal or plastic tube) in the esophagus to treat strictures (narrowing of the esophagus) or obstructions caused by cancer or other diseases. The stent acts as a scaffold, keeping the esophagus open and allowing food and liquid to pass through to the stomach.
Esophageal stenting can be performed using a flexible endoscope, which is a long, thin tube with a camera and light at the end that is passed through the mouth and down into the esophagus. The stent is inserted through the endoscope and positioned at the site of the stricture or obstruction. The stent is then expanded to the appropriate size, using a balloon or other mechanism, and left in place permanently or for a specific period, depending on the patient's condition.
