This topic is about a wheelchair user who is experiencing issues with their colostomy bag leaking due to a skin divot near the stoma. This can be a frustrating situation, especially when it affects daily activities like transferring from the wheelchair. Here are some suggestions and insights that might help:

1. Consider using convex barrier rings to fill the dip around the stoma. Some options include:
- Hollister Convex Barrier Rings, which come in both round and oval shapes and are flexible.
- Eakin Cohesive Barrier Rings, which can be used alongside convex bags.
- Salts Barrier Rings, if you prefer to stay within the same brand.

2. Try different ring thicknesses to see which works best for you. You can request free samples from each manufacturer to find the right fit.

3. Reach out to a stoma nurse for personalized advice. You can find one through your hospital or your supplier, such as Respond Healthcare.

4. Some people have found success with the Coloplast Brava Protective Seal. You can order free samples from the Coloplast website to try it out.

5. Remember, it might take a few tries to find the right product. Skin compatibility and leak prevention can vary from person to person, so testing different rings and seals is important.
