I have no regrets either, but there definitely are those who, in hindsight, wish they had not had it. This is mostly due to poor outcomes, complications, etc., that led to failure and ileostomy. They feel that for them, opting for ileostomy would have been a better option. But, none of us have a crystal ball, and that is why it is such a difficult choice. It IS a big decision and it can be life altering. Hopefully, it is life altering in a good way.
I had plenty of complications, some quite serious, yet I am very happy to have had the option for a j-pouch, since most of my life only an ileostomy was available.
One thing I need to caution you about, and that is choosing surgery solely for the reason to avoid drugs. I say this because there is no guarantee that you will be drug free after colectomy, as IBD can continue in the retained rectal cuff, as pouchitis, or even later be found to be Crohn's. In addition, you can develop related autoimmune diseases that require the same drugs. My point is, that it is best to choose colectomy and j-pouch to improve your quality of life, with a hope of eliminating or reducing your drug use. But, if that is your primary or only reason, you can be setting yourself up for a big disappointment.
I am one of those people. I still take Azulfidine, Simponi (formerly Humira), occasional prednisone and Flagyl, and a few other things. But for me, I am happy because I am functional and able to live well.
