I am a colostomate for 2 years. I have used a closed bottom 2-piece system from the beginning. I prefer to take the bag off, empty it, and rinse it out, then snap it back on. 6 months ago, I started using bag liners—it's even easier. When I am traveling or working (construction), I can change the bag liner, throw away the old one, and put in a new one. Much less handling.
Here is the problem. I had a peristomal hernia repair in January. Now my stoma is retracted, and no wafer is working. Flat bottom convex wafers don't reach the bottom of my "cone" stoma, and I am ALWAYS pancaked. Marlen seems to make a bowl-shaped flange on their one-piece system, but not a bowl shape in 2-piece. I feel closed-minded now to use a one-piece pouch, but perhaps I should reconsider. Please comment. Thank you.
