Esophageal Stent Procedure
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
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.
Why might I need an esophageal stent procedure?
You might need an esophageal stent for a number of health problems. It's most often
done to treat esophageal cancer. Stents are also used to treat:
Cancer of the top part of the stomach
Narrowing of the esophagus from an ulcer
Narrowing of the esophagus from radiation treatment
Abnormal opening between the trachea and esophagus
Hole in the esophagus
Any of these health problems can cause dysphagia. Dysphagia is serious because it
can lead to aspiration. During aspiration, you inhale food and stomach contents into
your lungs. That can lead to complications like pneumonia. Dysphagia also lowers your
quality of life. An esophageal stent can help ease these problems.
Even if you have esophageal cancer, you may not need an esophageal stent. In some
cases, your healthcare provider may be able to treat your cancer with surgery or chemotherapy
instead. If these therapies won’t work for you, an esophageal stent may be another
option. In other cases, a gastrostomy tube or jejunostomy tube might make more sense
for you. These tubes go straight from your outer abdomen to your stomach or small
intestine. Talk with your healthcare provider about all your treatment choices.
What are the risks of an esophageal stent procedure?
Esophageal stent procedures are relatively safe. But they do sometimes cause problems
later. These might include:
Pain in the esophagus
Bleeding (usually mild)
New hole in the esophagus (rare)
Movement of the stent
Tumor growth into the stent
GERD or heartburn (gastroesophageal reflux)
There is also a risk that you will need a repeat procedure because of one of these
complications. Your own risks may vary based on the nature of your esophageal problem,
your other health problems, and the type of stent used. Talk with your healthcare
provider about all your concerns.
