The topic at hand is about preventing "pancaking" in ostomy bags, which is when the output sticks around the stoma instead of dropping into the pouch. This can be a common issue for those using ostomy systems, and the person seeking advice is using a Hollister two-piece system, has a hernia, and is looking for better solutions and brand suggestions. They are also curious about what a convex appliance is and which lubricants others prefer. Here are some helpful tips and insights:

1. Keep some air in the pouch to prevent a vacuum effect. If you do this, make sure to cover the filter or switch to pouches without filters, as filters on most brands tend to clog quickly.

2. To maintain moisture and help thin the output, increase your fluid intake or add a little liquid to your diet. This is especially helpful for those with ileostomies.

3. Use pouch lubricants or deodorants to help the stool slide down more easily. Some popular options include:
- Hollister Adapt Lubricant
- Coloplast Brava Lubricant packets (scented)
- Safe & Simple Unscented Lubricating Deodorant (large bottle)
- Generic or insurance-supplied lubricating deodorants
It's a good idea to apply these after every empty or after a thorough pouch rinse to make them last longer.

4. Rinse the pouch with water each time you empty it. This keeps the walls slick and helps keep the filter cleaner.

5. If your stoma is flush or retracted, try using a convex barrier. Convex wafers push the stoma outward, improving drainage. Pairing a convex wafer with a thin barrier ring, like the Hollister 8805, can enhance the seal.

6. Consider trying alternative systems for a better fit or additional support. Options include:
- Coloplast SenSura Mio Flex two-piece
- Coloplast or Hollister elastic belts for light support
- Stealth Belt for high support, though it can add pressure. Cutting an opening opposite the stoma or switching belts may relieve pressure on the front of the stoma.

7. For better sleep positioning, place a small pillow against the pouch, avoid sleeping on your right side if it worsens pancaking, stop eating 3 hours before bed, and keep some gas in the pouch overnight.

8. If sitting triggers pancaking, try standing and moving briefly whenever you feel output starting so it can drop. Also, avoid tight garments or accessories across the stoma area.
