This topic is about dealing with the challenges of open sores and bleeding stretch marks caused by frequent wafer blow-outs after ostomy surgery. The person is six weeks post-surgery and is using a two-piece ostomy system. They are experiencing issues with the adhesive wafer lifting multiple times a day, which is causing painful sores around the stoma. Here are some helpful insights and advice:

1. Consult with an experienced ostomy nurse or dermatologist as soon as possible. They can provide a professional assessment of the skin around the stoma, which is often necessary.

2. A poor fit is a common cause of wafer leaks, especially in the early months post-surgery. The stoma size and output pattern can change, so it's important to keep re-measuring and adjusting the fit.

3. Consider trying convexity:
- Some users have found success with the Coloplast two-piece Snap-Lock system with a mild convex barrier, which can help stop seepage.
- Coloplast Alterna convex wafers, combined with closed pouches and an adhesive-remover spray, can stay on for 4–7 days and leave the skin clean.

4. One-piece vs. two-piece systems:
- Users with liquid, unpredictable ileostomy output often prefer a one-piece convex wafer with Adapt paste, as it reduces the chance of "seal separation."
- Two-piece systems are designed for thicker, more predictable colostomy output, allowing the pouch to be changed without disturbing the wafer.
- Belts or elastic waist supports can help some people, but they don't work for everyone.

5. Barrier products and skin protection:
- Use alcohol-free skin-barrier wipes, like Convatec Sensi-Care, before each application.
- Form Hollister Adapt Barrier Rings or other moldable rings into a thin "worm" to create an adhesive-free seal around the stoma. Smaller strips can fill creases or cover tender stretch marks.
- Protective powders should only be used on broken skin. Once the area is dry and healed, discontinue use so the wafer can bond properly.

6. Adhesive remover sprays can reduce skin trauma during wafer changes and help protect fragile, stretch-marked skin.

7. Sample different products from manufacturers like Hollister, Coloplast, Convatec, Braun, and Eakin. They often provide free samples upon request.

8. Change frequency matters. Some users limit wear-time to 2 days for easier, less painful removal and to prevent residue from hardening.

9. For intimacy or swimming, a two-piece Convatec system with convexity allows for quick swapping to a mini-pouch or discreet stoma cover, then back to a full-size pouch.

10. Allow the skin to air out for a few minutes during changes. Exposure to air and light can help sores heal more quickly.

11. Expect a trial-and-error period of 3–6 months. Focus on solving one issue at a time and stay connected with support communities for practical tips.
