This topic is about finding a better fit for stoma appliances, especially when sample products work well but full-sized orders tend to leak. The person in question has a 1-inch protruding stoma and currently uses a setup that includes a ring barrier, a skin barrier, and a one-piece, drainable flat pouch. They are considering whether switching to a convex pouch might help with the leakage issue.

Here are some helpful suggestions and insights:

1. Consider using a convex pouch. Many people with a protruding stoma find that a convex pouch provides a better seal compared to flat systems, which can help prevent leaks.

2. Try adding external reinforcement strips. Some users have had success with Brava Elastic Barrier Strips from Coloplast, which help secure the edges of the baseplate and significantly reduce leaks.

3. Explore a DIY custom baseplate system:
- Use plastic cut from 5-gallon containers for daytime and thinner 1-gallon plastic for nighttime.
- Attach proprietary flanges to the plastic so that only the plastic touches the skin.
- Use two holding belts, one at the top and one at the bottom, to stabilize the plate. Design the attachment points so the belts release only when intended.
- Pair this setup with Coloplast SenSura two-piece drainable bags for easy cleaning and extended wear time.
- Secure the plastic plate with spray-on medical adhesive, which may adhere better and be gentler on the skin than standard wafer adhesive.
- This DIY setup can allow bags or sleeves to stay in place for one to two months, reducing leaks and skin irritation.

4. Be persistent and willing to experiment. Every stoma is unique, and it often takes a combination of commercial products and DIY solutions to find a setup that is leak-free.
