In my honest opinion, if it is not broke do not fix it. If you can live with an ileostomy and your not having any problems, I would choose the ileostomy. An ileostomy did not work out for me so a J-pouch was way better for me. So far its been almost 6 years and I am doing perfect with nothing wrong.
I am a J-poucher that goes anywhere between 13-20x a day, I am in the 9% of the J-pouch community that goes that often- and honestly after a while, you get use to it. Some days can be harder than most but I am honestly doing okay with it. My pouch has given me peace. If you are in the 9% with me, its going to be okay
I am a rare case though, 9% is pretty low.
