Topic Explanation
The discussion revolves around choosing between one-piece and two-piece ostomy systems. The original poster (OP) has been using a two-piece system with a closed bottom for two years, preferring to remove, empty, and rinse the bag before reattaching it. Recently, they started using bag liners for convenience, especially while traveling or working in construction. However, after a peristomal hernia repair, the OP's stoma became retracted, causing issues with wafer fit and leading to pancaking. The OP is considering switching to a one-piece system, particularly one with a bowl-shaped flange, and seeks advice on this potential change.

Advice and Insights
1. Preference for Closed vs. Drainable Bags:
- Some users prefer closed-end bags for ease of disposal, while others find drainable bags more convenient for frequent emptying.
- Adding warm water to a drainable bag can help with emptying thick waste without squeezing.

2. Stoma and Wafer Fit Issues:
- Retracted stomas can cause pancaking and wafer fit issues. Some users suggest considering a stoma revision if the retraction is problematic.
- Using a convex one-piece system can help bring the bag opening closer to the stoma, potentially reducing pancaking.

3. Product Recommendations:
- The Convatec Active Life pouch and Esteem Body one-piece drainable systems are mentioned as effective options.
- Contacting manufacturers for samples and advice from ostomy nurses can provide tailored solutions.

4. Personal Preferences and Situations:
- Manual dexterity issues or personal convenience can influence the choice between replacing or emptying bags.
- Some users find it easier to replace bags due to limited dexterity or the nature of their waste output.

5. Cost and Waste Considerations:
- Frequent emptying or replacing of bags can be costly, and some users find ways to minimize waste, such as using bag liners or reusing bags.
- Insurance coverage and regional healthcare systems can affect the affordability and availability of supplies.

6. General Advice:
- Trying different systems and configurations is encouraged to find what works best for individual needs.
- Consulting with healthcare professionals and other ostomates can provide valuable insights and support.
