I first was just diverted from using j-pouch to an end ileostomy and 6 months later had my j-pouch removed and still used the end ileo. I could have saved an operation if I'd had the j-pouch removed during the first surgery like the doctors recommended. My j-pouch didn't get better during the 6 months inbetween surgeries.
She was able to do the first surgery laproscopically but the surgery to remove it has to be open. The biggest hurdle I had was getting my rear end to heal up but others have had no problem.
The end ileo is much better than the temp ileo I had in-between the j-pouch surgeries .
The diverting and then removal surgeries were done at the Mayo Clinic. I've heard about major problems with the removal surgery so hope you are using a surgeon with a lot of removal experience.
Sorry your j-pouch failed
