The topic at hand is about finding a supplier for extra-large ostomy bags, specifically for an ileostomy. If you're in need of such bags, here are some helpful suggestions from the community:

1. Reach out to Parthenon, a supplier based in Utah, by calling 800-453-8898. Many people have found that they offer very large pouches.

2. Compile a list of all ostomy suppliers in your area, especially those that handle NHS prescriptions if you're in the UK. Contact them to request free sample packs so you can compare the sizes available.

3. Consider trying the Hollister 8081 one-piece pouch. Users have described it as "HUGE" and appreciate its large capacity.

4. If you find that commercial pouches are still not large enough, you might try using irrigation sleeves as makeshift extra-large bags. You can fold the sleeve over and seal the end with a freezer-bag clip or tuck it under your ostomy belt. Keep in mind that these sleeves do not have charcoal filters, so they might allow odors to escape. They are best used for emergencies or overnight situations.
