Tom, your question brings to mind precisely the reason I never recommend anyone have a colectomy simply to avoid taking medications. Nobody knows what lies in their future and you are only inviting disappointment if the success of your surgery depends on whether or not you can be drug free.
Only about a third of UC patients need a colectomy sometime in their lifetimes, so it is not a given. Regardless of whether or not a j-pouch or ileostomy provides a carefree life (it usually doesn't, but most people downplay the negative because they are healthier), that same group would still require the colectomy. Colectomy does not cure IBS, anxiety, or even IBD. It only cures colitis in the portion that has been removed (or polyposis, or cancer, or inertia, or whatever).
It is regrettable that you and other patients were told that somehow j-pouch surgery was some sort of panacea, but in truth there is NO OPTION that is perfect, including keeping the diseased colon.
As for myself, yes, I did keep my colon as long as I could, but when medical management failed, including high dose steroids, my choice was colectomy or bleed to death. People who have the surgery under less urgent conditions seem to have more trouble accepting an outcome that is troublesome, probably because they are second guessing their decision.
My feeling is that second guessing an irreversible choice serves only to cause more grief, so why even go there? It is like playing "what-if" if you got into a car accident that caused you to loose an arm or a leg. Fretting about "what-if" you never got in the car that day does not bring back the lost limb.
If it were me (and I have had many, many complications) I would focus on what my current choices are and how do I improve my current situation. Hopefully, Cipro will take care of your pouchitis and you can be turning that corner you have been waiting for.
