Esophageal stent treatment

Understanding your treatment

Esophageal stents are often used to treat the side effects of cancer of the esophagus by using a tube, or stent, to keep the blocked area open. There are various types of innovative stents available from Boston Scientific and your doctor will work with you to find the best solution to fit your life.

There is a covered and an uncovered Ultraflex stent. These stents are designed to maintain luminal patency in esophageal strictures caused by intrinsic and/or extrinsic malignant tumors.

Recovering from your procedure

Your esophageal stent procedure will likely be performed on an outpatient basis. After your procedure, you will rest and recover as your care team monitors your progress for a few hours. As you are ready, the doctor will release you to go home. Make sure someone is there to drive you as you will still be unsteady from the anesthesia. Discomfort immediately following your procedure is normal. Your doctor may prescribe you over-the-counter pain medicines as you need them.¹

Eating with your stent

Once the stent has been placed, your medical team will advise you on when it is safe to start eating and drinking again. You will start with fluids and then build up gradually to a soft diet. Depending on your type of stent, it can typically take one to two days for the stent to fully expand, so take it slow at first and eat small meals made up of soft foods.

Foods to avoid

The stent has been placed to allow you to eat as normally as possible. However, it is possible for the stent to become blocked. The most common reason for blockage is from food that is swallowed without being sufficiently chewed or from foods that do not break down enough when chewed. The following foods can be difficult to break down, despite chewing, and so are more likely to cause your stent to become blocked: 

  • Bread and toast

  • Tough and gristly meat

  • Hard boiled or fried egg

  • Fish with bones 

  • Oranges, grapes and pineapple

  • Stringy vegetables (e.g., greenbeans, celery)

  • Potato skins

  • Salad items (e.g., salad leaves and lettuce) 

  • Raw vegetables

  • Chips

  • Ice cream or yogurt with chunks of fruit, cereal or nuts

Tips for eating with your stent

  • Take your time, and eat slowly

  • Eat small meals. Aim for 5 to 6 small meals a day rather than 3 large meals

  • Cut your food into small pieces, take small bites, and chew thoroughly 

  • Use sauces, gravy, and cream to add moisture to your meals. This will help food pass through your stent 

  • Drink throughout your meal to help clear your stent. Warm or carbonated beverages are recommended, but all fluids are beneficial. For some people, carbonation may worsen symptoms of heartburn or acid reflux

  • Sit up straight as you are eating and for a few hours afterwards

  • If you take pills, ask your doctor if they are available in liquid form

What to do if you feel your stent is blocked

  • Do not panic. The blockage only affects the tube in your stomach and not your ability to breathe

  • Stop eating, stand up, and take a few sips of water

  • Try a carbonated beverage

  • Walk around 

  • If the stent blockage has not cleared after one or two hours, contact your doctor or nurse

When to call your doctor

Call your doctor immediately if you experience the following: 

  • Fever

  • Sever acid (gastroesophageal) reflux

  • Persistent swallowing problems 

  • Pain that persists longer than 72 hours or is severe

Regular follow-up visits

It’s important to maintain all follow-up visits, even if you’re feeling well. During these visits, your doctor will monitor your progress, evaluate your medications, check the status of your overall health and determine the success of your stent procedure.
