Did the doc say anything about him having a yeast infection under the pouch? That may be what's causing the bleeding rash (unless it's where the skin is ripped off by removing all those bags! Ouch!)
I used a powder under there called Zeasorb. It can usually be found where you'd find foot powders at Walmart and Walgreen's and it's pretty fast acting.
How long has your husband had the pouch?
I had this very same problem with my pouch. Could not get a bag to stick for anything. Even the hospital and the stoma nurses were at a loss and couldn't help. Because of this, they did a pouchoscopy after only 2 months to see if the newly created pouch had completely healed. It had, so they did the next step right away. They usually wait for 3 months. Maybe they'd be willing to move the next surgery date up for him.
What these surgeons have been doing, is creating a stoma that is too short. When the stoma retracts, stool leaks out behind the barrier ring. All that acid burns the skin and melts the adhesive so the bag won't stick.
The big problem is, the adhesive only melts in certain areas causing the bag to leak, so you have to remove the bag in order to attach a new one. All that adhesive that didn't melt, sticks really good!!! So when you remove it, it rips your skin off with it. Then you have to put new adhesive on totally raw skin; sometimes, several times a day. If you think that's what's happening to your hubby, you can pm me. I may be able to help a little bit, but like I said, in the end I just had to get that bag off me as fast as possible.
I really feel for him. I've never lived through such a living hell as those two months.
For those of you contemplating this surgery, don't let this scare you off, but it might be wise to investigate ahead of time and find a surgeon who will creat a stoma that will actually reach inside the bag.
My stoma nurse told me this has happened because there was a cocky surgeon somewhere who taught a bunch of new surgeons how to do this surgery. If I remember right, he accidentally made the stoma too small, but that was what the new guys/gals saw, so that's how they make them.
Praying for a good outcome for your husband.
