James,
Welcome to the forum.
Yes, it's a hard place to be. I've been exactly where you are now.
None of the meds worked, and my doctor finally gave me a choice of remicade or surgery; I refused both and found my own way.
I would suggest as IAS said, to exhaust all options before surgery.
And there are many things you could try in combination IMO:
diet modification, supplements, certain amino acids, probiotics, and LDN, low dose naltrexone.
If you'd like more info on these, please check out the link in my sig.
I hope you start feeling better soon.
