Statistics on surgery rate it anywhere from 90-97% success so that's a bit higher than what you have read.
Surgery is most often done in 2 steps but if you have been off of pred for a while you might be a candidate for a one step. I had the two step and was back to work 3 weeks from the day I had surgery. Mine is considered a quick recovery, most people are out 6 weeks after their first surgery. If you are contemplating surgery I would find a very experienced CR surgeon, one with lots of jpouches under his/her belt. You can get recommendations for surgeons in your area at www.j-pouch.org I chose to travel 2 hours to see one of the nations top surgeons and I believe his experience (over 2000 pouches) is responsible for my successful recovery.
Even those who have had less than perfect surgery results all say they are glad they did it.
