What is an esophageal stent procedure?
An esophageal stent is a tube placed in your esophagus to keep open a blocked area. The tube helps you swallow solids and liquids.
Your esophagus is the muscular tube connecting the back of your mouth to your stomach. When you swallow, the muscles of your esophagus contract. They propel food into your stomach.
Many health problems can partly block a portion of your esophagus. That can make it hard to swallow. The medical term for this is dysphagia. You might have pain when you swallow or feel like food is getting stuck in your chest. The food might come back up after you swallow. An esophageal stent can help reopen your blocked esophagus and ease symptoms.
The procedure might take place under general anesthesia or conscious sedation. If it takes place under general anesthesia, you will sleep through the procedure and feel no pain. If it takes place under conscious sedation, you will get medicines to make you relaxed and sleepy. The surgeon may numb the area under surgery so that you won’t feel much pain.
During the procedure, the surgeon places a long, thin tube (catheter) down the back of your mouth and into your esophagus. Next, the surgeon places a collapsed hollow tube (stent) over the catheter in the correct position across the blockage. The stent expands against the walls of your esophagus, giving support. Then the surgeon removes the catheter and leaves the stent in place.
