I'm getting a permanent ileostomy after a 25 yr j pouch. I just starting researching and I didn't even realize that there was such a thing as one piece bag. I have seen some of the pros and cons, but what do you people think or use. Seems like the two piece system gives you more flexibility. I am a very active person who does a lot of sports and swimming, etc.
I've only used 2-piece. I like to "burp" my bag at the flange to get the air out. I think most one-pieces have filters to keep gas out of the bag (I personally didn't like using filters), or you can release air from the bottom opening. I can also put a fresh bag on the 2-piece without replacing the wafer itself if I feel like it.
OTOH, I understand with 1-pieces some people report fewer problems with leakage. Lots of pros and cons to both. The hospital will be putting you in their set-up initially, which will probably be a 2-piece. Later, you can start experimenting with different types of products (contact the Hollister, Convatec, Coloplast, etc. for free samples). There's also a facebook group called "The Real Ostomy Support Group" that's given me lots of good tips re. ostomy equipment and care that you can check out if you are interested.
I like opaque bags. Not clear bags I know what's in there I really don't need to see it except to empty.
But I also use a 2 peice. Drsinabke. I put the flange on first. I have pre cut wafers. Fit perfectly. But I don't think I could get a one peice centered over my stoma correctly.
I'd have to use a clear bag to do to a one peice.
I found one piece systems work best. I personally don't like filters so don't have them in the bag. I empty gas from the bottom.
Richard is right. I prefer clear bags on the front as it helps when changing.
I use a convex wafer and have tried about every brand.
Start out with what the stoma nurse sets you up with. I also changed it myself at the hospital so I was good with it when I went home.
I hope all goes well.
