Hi Roberto. I just had the j-pouch recently removed. It went smoothly and iniy took the surgeon 4-5 hours to remove. However, I did have a temp ileostomy prior, so the surgeon also had to change the ileo to an end ileo. I’m not sure how much more complicated the surgery if you are going to have the j-pouch removal and ileo creation all in one surgery.
Hope the surgery goes well should yoh choose to do the surgery.
