I am close to surgery but still hanging on for the same reasons Eva Lou and notsosicklygirl posted... Had a surgery consult, but it is hard to get a handle on the complications issue. I know jpouch.org is a support forum for those with problems, but I loosely follow when people are about to get surgery and see how things develop, and the complication rate (infections/obstructions requiring more invasive procedures, chronic pouchitis, poor function, etc) that I observe looking at those who do post before surgery - before any complications -seems *much* higher than the 5% or so quoted by the surgeons and surgery centers.
One stat that blew me away was that 50% of all jpouchers do get pouchitis from time to time- even though mostly it is non-chronic and easily treated with antibiotics. But that means having to use antibiotics - something that kills good not just bad bacteria, and which as best as I can tell was what flared me at least twice- as much as a normie uses say aspirin. Another stat was that most jpouchers have at least one nighttime emptying of their pouch- hardly a great way to have a good night's sleep. I am sometimes puzzled how almost all the jpouchers nonetheless say their life is so much better than with UC... but it still seems a tough price to pay. However I accept I'll likely need it soon.
