A colonic stent is a small tube that is inserted into the colon to help keep it open. Here are some details on how long colonic stents typically last:
- Metal stents - These are the most common and durable type of colonic stent. Metal stents can remain in place for several months on average, though some may last up to 12 months.
- Plastic stents - Plastic stents are less commonly used in the colon. They may only remain functional for 2-3 months on average before needing to be replaced.
- Biodegradable/dissolving stents - These newer types of stents are made of materials that gradually dissolve over time, such as certain plastics or gelatinous substances. They may last around 2-3 months on average before dissolving.
- Expandable stents - These stents can be inserted small and then expanded in place to widen the colon. They are often metal and can last for many months, though less durable than standard metal stents.
The lifespan of a colonic stent depends on the material, location in the colon, and reason it was inserted. Your doctor will determine when it needs to be replaced based on your specific situation and symptoms. Let them know if you experience any return of symptoms so the stent can be evaluated.
