Wow. It would seem that an operation to correct a stoma that is in a place that cannot support it and does not allow it to work properly, that your insurance would cover that! I had a plastic surgeon do my Barbie Butt and the incision goes from just below my Breast bone down to my bikini line. My stoma was placed in a really good spot but it would have been too close to my belly button so the surgeon just moved my belly button over. I teased him about it asking if he knew any plastic surgeon that could draw a straight line. Lol
This is not pretty but it made my ostomy life way better than it would have been. This has also caused one side to be more puffy, The opposite side of my pouch. I am probably the only person that notices it.
Do what you feel comfortable with. I could never imagine having to deal with leaks as long as you have. I did the first few months until I found the pouch system that worked for me.
