Topic Explanation:

The forum discussion revolves around a user seeking advice for their wife, who is experiencing frequent leaks with her new inverted oval-shaped stoma. They are using a Hollister system with specific products, but the leaks are causing distress. The user is looking for suggestions on products or techniques to prevent leaks and improve the situation.

Advice and Insights:

1. Convex Wafer Recommendation:
- If the stoma is flush with the skin, a convex wafer is recommended. If the stoma is retracted below the skin, surgical intervention may be necessary.
- Consider using a moldable barrier that conforms to the stoma, such as Convatec's SUR-FIT Natura Durahesive Moldable Convex Skin Barrier.

2. Barrier Ring and Wafer Application:
- Warm the barrier ring before application to improve adhesion.
- Ensure the skin around the stoma is very dry before applying the wafer.
- Use a thinner barrier ring if the current one is causing issues with inversion.
- Consider using a Magic Bag or similar to promote adhesion after application.

3. Cleaning and Preparation:
- Clean the area with water only, avoiding creams that may cause issues.
- Use a barrier wipe to protect the skin and aid adhesion.
- Ensure all adhesive remover is thoroughly washed off.

4. Product Suggestions:
- Coloplast Convex appliances and barrier rings were recommended by several users.
- Hollister's CeraRing Convex Barrier Rings and Coloplast's deep convexity wafers were suggested for better fit and adhesion.

5. Routine and Technique Adjustments:
- Consider adjusting the routine, such as not eating or drinking several hours before changing the appliance.
- Use a hair dryer to warm the ring and flange before application.
- Apply light pressure over the stoma after applying the new appliance to ensure secure adhesion.

6. Monitoring and Adjustments:
- Regularly check the size of the stoma, especially in the initial weeks post-surgery, as it may change.
- If the ring is swelling and blocking output, consider repositioning it or using a different thickness.

7. Consultation with Healthcare Professionals:
- Make an appointment with an ET nurse for a new fitting and to assess the stoma in different positions.
- Discuss with the surgeon about the possibility of surgical correction if the stoma is deeply re
