GI Stricture Dilation is a non-surgical method used to stretch open narrowed areas (strictures) within the digestive tract, making it easier for food and liquids to pass through.
Common Indications for GI Stricture Dilation
Your doctor may request this procedure if you have:
- Severe difficulty swallowing food (dysphagia) due to narrowing in the esophagus.
- Scarring in the esophagus from severe acid reflux (peptic strictures).
- Narrowing caused by benign conditions or previous digestive surgeries.
What exactly does the procedure do?
Instead of cutting the scar tissue out, the interventional radiologist uses a specialized medical balloon to forcefully stretch the narrowed tissue from the inside out, restoring the normal width of your digestive tract.
What happens during the procedure?
You will lie on an X-ray table. Using continuous fluoroscopy (X-ray video), the doctor safely navigates a deflated balloon down your throat to the exact location of the narrowing. The balloon is then inflated with a liquid that is highly visible on the X-ray screen. The doctor watches as the balloon expands and effectively breaks up the scar tissue. Once the area is stretched, the balloon is deflated and removed.
Do I need to prepare?
Yes. Your stomach must be completely empty. You will be asked to fast (no food or drink) from midnight the night before, or for at least 6 hours prior to your appointment.
How long does it take?
The dilation process is relatively fast, usually taking 30 to 45 minutes.
Will it be painful?
You will be given IV sedation to help you relax. When the balloon is inflated, you will likely feel a strong stretching, pressure, or a sensation of fullness in your chest or abdomen. This discomfort is very brief and subsides the moment the balloon is deflated. You may have a mild sore throat for a day or two following the procedure.
Conclusion
GI stricture dilation provides immediate, dramatic relief from swallowing difficulties without the risks of major surgery. By gently but firmly opening the digestive pathway, it allows patients to comfortably return to eating normally.
