This topic is about dealing with persistent leaks, pancaking, and lifting issues around the belly button when using the SenSura Mio Convex Light system. The person sharing their experience is facing daily leaks, especially during sleep, and is looking for solutions to improve their situation. Here are some helpful tips and advice that might be useful:

1. Venting and Gas Control
- Consider using Osto-Ez Vents instead of making needle holes in the pouch. These vents adhere over a punched hole, allowing gas to be released and then resealing.
- Some people prefer "burping" a 2-piece Hollister bag by lifting the top tab of the pouch flange.
- You can also try using a syringe to introduce water through the vent to help with pancaking.

2. Keeping the Belly Button Out of the Adhesive Field
- Trim or custom-cut the wafer opening so it doesn't cover the navel.
- Fill the navel indent with a piece of moldable barrier ring before applying the wafer.
- Use SafeNSimple X-tra Wide Skin Barrier Arc or Hypafix tape over the edges prone to leaks.

3. Reinforcement and Support
- Apply Hypafix tape across the fabric edge, ensuring the ends stick to the skin to prevent lifting. Use adhesive-remover spray or wipes for easy removal.
- Consider using larger full-circle support belts or stretchy wraps for even pressure, as small 2-point belts may tug at the flange clips.

4. Skin Preparation
- Avoid using products like Aveeno Dry Skin wash and fresh aloe, as they may leave a residue.
- Clean the skin around the stoma with plain warm water and a soft cloth, then dry thoroughly.
- After using adhesive-remover wipes, wipe the area again with plain water to remove any residue, and finish with a skin-barrier wipe or spray on clean, dry skin.

5. Product Trials and Supplier Help
- If the current system continues to fail, request samples of other systems from suppliers like ConvaTec, Hollister, or Coloplast.
- EdgePark and manufacturers often provide free samples, so keep experimenting to find what works best for your body.

6. General Tips
- To reduce pancaking, keep a small amount of air in the pouch, add a few milliliters of water or lubricant through the vent, and empty the pouch more frequently.
- Maintain a food and output diary to identify foods that may thicken output excessively or cause high gas, which can worsen pancaking and pressure.

These suggestions aim to help manage the challenges faced with the current setup and improve the overall experience.
