The topic at hand is about whether it's too late to start colostomy irrigation after having a colostomy for over four years. The person is curious about this process, having heard that many with colostomies are good candidates for irrigation, but they have been hesitant due to concerns about inserting anything into the stoma. They are now wondering if they can still begin this practice.

Here are some helpful insights and advice:

1. It's never too late: Many people have successfully started irrigating years after their surgery. The time since your operation doesn't prevent you from beginning irrigation if you're otherwise a suitable candidate.

2. Check with your healthcare provider: It's important to consult with your surgeon, ostomy nurse, or another healthcare professional. They can confirm that your remaining descending colon is healthy and that there are no medical reasons preventing you from starting irrigation.

3. Learn from resources:
- The Ostomy Association of America website provides detailed information about irrigation.
- There are numerous instructional videos on YouTube that can guide you through the procedure step-by-step.

4. Enjoy the benefits: Regular irrigation can significantly reduce or even eliminate the need to manage a pouch during the day, offering you more freedom and convenience.

5. Seek support: Those who have experience with irrigation are often willing to offer personal guidance and support, so don't hesitate to reach out to them if you need help.
