This topic is about finding solutions for a lopsided stoma, which can make it tricky to get a good fit with an ostomy wafer. The person has an ileostomy and is dealing with a stoma where one side protrudes more than the other, causing the wafer to lift on the lower side. They are currently using a Convatec two-piece system with a convex wafer, paste, cohesive rings, and a tightly pulled ostomy belt, but these haven't provided a lasting solution. They are seeking advice on other products and brands to try.

Here are some helpful suggestions:

1. Convexity options:
- Make sure the convexity depth is appropriate; too much convexity can also cause lifting.
- Marlen offers a shallow-convex appliance that some users find sticks better. It's a good idea to request samples.

2. Level the skin surface:
- Use paste as a caulking agent to fill in dips rather than as an adhesive.
- Cut the wafer opening close to the stoma and fill any low areas with paste.
- With a barrier ring, press it thinner on the side where the stoma protrudes more and leave it thicker under the shorter side to create an even surface.

3. One-piece vs. two-piece systems:
- Some people find that a one-piece system stays flatter because removing the pouch from a two-piece flange can cause the edges to lift.

4. Alternate manufacturers and sources:
- Coloplast: Some users have switched from Convatec and report good customer service in the U.S.
- Hollister: Another major brand to consider for sampling.
- Marlen: Offers a shallow-convex one-piece system.
- Convatec: The brand currently in use, known for a broad product line.
- Online supplier: www.edgepark.com carries Coloplast, Hollister, Convatec, and Marlen products and provides catalogs and ordering.

5. General tips:
- Request samples from each manufacturer to test different wafer depths and adhesives.
- Continue using the belt if it helps, but adjust it once the wafer adheres properly to avoid discomfort.
