wafer that dont swell around stoma

Yes. Convatec 400598 is a one piece flat, not convex, clear, no vent, clip closure. I wore it for a long time, but now my stoma is retracted and I need a convex wafer. The 400598, 400599 opaque, is soft and very comfortable. You will need OSTO EZ VENTS for venting. It does not turtleneck. When my stoma retracted it would go sideways and force the sewage under the wafer and out.

Don't forget the vents......you MUST have them for venting.

I am using convatec one piece convex, clear pouch, no vent, clip closure. It comes by stoma opening size. I use 7/8 inch. The part number is 125353. The wafer is hard so it can bring your stoma out and seal around it. It does not turtleneck. I cover the whole wafer area of my skin with Friars balsam compound. Stops any irritation and helps the wafer adhesive. It also comes in a two piece. I am really pleased with it. I have gone 6 days and could have gone longer. If you get your supplies from Edgepark they will send you a catalog.
