Luminal Stent Q&A

What is a luminal stent? 

A luminal stent is a small plastic, silicone, metal, or wire mesh tube that your Advanced GI LLC physician places within your gastrointestinal (GI) tract. 

Stents open up blocked areas within the esophagus, intestine, or elsewhere in your GI tract. The stent remains in place to prevent recurrence and offer long-term support. 

When do I need a luminal stent? 

If you have any type of GI tract blockage, or you're at-risk for a serious blockage, your Advanced GI LLC gastroenterologist may recommend a luminal stent. 

Esophageal stents

You may need a luminal stent in your esophagus if you have difficulty swallowing or have other symptoms related to esophageal blockages.

Duodenal stents

You may need a duodenal stent if you have a small intestine obstruction that prevents normal food passage. This stent goes in the duodenum, the top part of your small intestine. In some cases, a duodenal stent can be an excellent alternative to surgical gastrojejunostomy, a gastric bypass procedure.


You may need a colonic stent if you have a narrowed or blocked area in your intestine. A colonic stent restores normal stool passage. 

The experienced gastroenterologists at Advanced GI LLC can discuss your specific problem with you to recommend the ideal kind of luminal stent for your needs. 

How does the luminal stenting procedure work?

You'll receive sedation to maintain comfort during the procedure. Your gastroenterologist uses an endoscope — a thin bendable tube that houses a light and camera — to view the obstruction. 

They use the endoscope to place the stent; then, your gastroenterologist slowly withdraws the endoscope.

What happens after luminal stenting?

After your luminal stenting procedure, you'll move to a recovery area until you're alert. Your gastroenterologist discusses the process and its results with you, and then a loved one can drive you home.

Follow your doctor's instructions for the fastest recovery. Usually, this means resting after the procedure and then resuming your normal routine when you're ready. You may need to follow a clear liquid diet for a couple of days following your procedure, as well. 

In many cases, a luminal stent can ease your uncomfortable GI symptoms and may help you avoid major surgery. Learn more by calling Advanced GI LLC or schedule an appointment online.
