The topic at hand is about dealing with a white film that sometimes appears on a colostomy stoma. This situation arose after someone had an ileostomy reversal and a new colostomy was created on the opposite side of their abdomen. They noticed this white film after switching to a different brand of ostomy appliances and are looking for advice on how to prevent it.

Here are some helpful insights and advice from the community:

1. The white film or gel is likely normal stoma mucus or a natural body lubricant, and it is usually harmless.

2. It's perfectly okay to feel unsure, but consulting a stoma nurse for confirmation can provide peace of mind.

3. If you're concerned, consider taking a photograph of the stoma and sharing it with a stoma nurse or physician for quick feedback.

4. One person found that switching from a flat wafer to a convex wafer with a wax barrier ring helped resolve similar issues of mucus and occasional bleeding.

5. Changing the type of wafer or barrier accessories, such as using a convex instead of a flat wafer or adding a wax barrier, can help reduce friction-related irritation, even if you stick with the same brand of appliances.
