Reasons I did not choose surgery over taking meds:
1. At age 18 my GI prescribed 20 mg (or less) of prednisone and my first flare went away after a few weeks.
2. My first remission lasted 3 years.
3. Subsequent flares became gradually more harsh and meds where increased but I still go into remission where almost all my symptoms go away (IBS-like symptoms remain somewhat).
4. Dating, college, vacations, work, physical activities would all be changed with surgery.
5. By the time my meds were strong enough to have risky side effects (5 years ago) I was so far along in my career, family and life that surgery would be a major impact over even the 2-3 flares that hospitalized me for a week or so.
I would choose a few months of prednisone every 3 years over surgery still. Imuran and Remicade (which I'm on now are a different matter but surgery is not without risk either and is life changing).
It's not an easy decision. I like my colon.
Everyone's symptoms and life are different; surgery may be best for you.
