Hi Mike,
Yeah, that Bill sure has it easy... wink, wink. What do you say about the ring choking off my stoma would be true if I had a normal stoma. I'll look later and see if I can find a decent (not too gross) pic of my stoma. The pic will explain all. But for now, think of my stoma this way... instead of my stoma sticking straight out of my abdomen at a 90-degree angle to my abdominal wall... lean it over to say a 30-degree angle so the opening that would normally be in the direct center of the stoma is now pointing to the right. The oval section of stoma you see when looking directly at me is more the side of the stoma, laid over, which forms an elliptical shape. So all along the circumference of that ellipse (except where the outlet hole is at skin level), the stoma skin is very thin... because it's leaning over and not sticking straight out. So the ring can't choke it off. Where the stoma exit hole is, it's at skin level and there is no stoma wall thickness. So imagine grabbing your stoma with your hand and bending it over until the hole points to the right and not straight out of you. Then push your bent-over stoma into your abdomen until the hole is right at skin level. That's my stoma. It's not as bad as that sounds, but it's not what one thinks of when you say normal stoma.
I do use a convex barrier, but where the barrier pushes on my skin adjacent to the exit hole, there's nothing there for the barrier to go around or grip, as there would be in a normal protruding stoma. My skin is just flat in that area with a small hole in it that stuff comes out of. So maybe it would be easier to think of it as a protruding stoma all around the ellipse and then on the one long end, there's an exit hole say at or just below skin level. If I could build up that area with some skin, or tip my stoma to point a little more upward, then the barrier ring would have something to strangle. Right now, the only thing that keeps me from getting a leak is pure adhesion of the barrier to my skin. My stoma is also in a bad location in terms of me bending. If I bend forward too much (like when I was sitting on the ground changing tires on a buddy's car), the skin tends to fold in the abdominal area, which can make the barrier lose contact. The other night, when I had a leak... the ring swelled, like you say, and blocked my stoma opening. So the stoma was shooting out liquid UNDER my barrier ring between the barrier and the skin because the ring blocked the top of the stoma opening. I was sitting there (and I can feel when a lot of liquid squirts out)... and I get that feeling, and then a feeling of something warm running down my side. I immediately knew something wasn't right and jumped up before I made a mess. I can't change my barrier until the morning, so I just cleaned it the best I could, pushed the ring out of the way through my bag, and kept my right side elevated all night to let gravity be my best friend. Slept on my left side and got up and changed my barrier in the morning. It was obvious what I did, and I now pay a lot more attention to how and where I place my barrier ring. I also slice off a small piece of another ring and build up my ring in the area where my stoma exits, creating a higher "wall" on that side. Wow... I'm writing a novel here. Couple more things... I do use a barrier film. After dusting off the stoma powder, I apply 3 barrier film wipes, drying the area thoroughly between wipes. Then I stuff a paper towel in and around my stoma to absorb any moisture/weeping while I place my ring on. Then I pull the paper towel off, stick the ring on, apply barrier, apply heat from a hairdryer over the entire area, and then cover with my palm for 45 to 60 seconds. Then I hit it with a paper towel one last time before putting my bag on (I use a 2-piece barrier). The whole barrier change takes me about a half hour. I didn't describe the skin prep right after I pull the old barrier off and up to the stoma powder, but it involves shaving, hitting the area with chlorine bleach, wiping that off, applying any medication if needed (either Flonase if the skin is in good shape or Betamethasone if it's bad), and then moisturizing outside the area the ring sticks to with O'Keeffe's. And to think the ostomy nurse I met right after my operation told me barrier changes were a snap! Like to "snap" her right up side her head. Ok, I'll go see if I can find a pic of this mess so you'll see what the heck I'm talking about.
Later,
Bob
