It sounds like they are considering a temporary diversion - that would be the one where they leave your colon in place but do an ostomy for the stool.
The idea is that your colon would have time to heal without any stool going through it and you could be hooked back up once it has healed.
I have heard good things generally about
the Cleveland Clinic but it sounds like you are really uncertain that you want to go ahead with surgery.
Have you considered getting a 2nd opinion somewhere? There are many good places to choose from that aren't that far from Cleveland. Chicago has a terrific program for one.
No matter how much you trust your current docs, sometimes a fresh pair of eyes can see options that have been overlooked.
Looking over the things you listed I wonder about
the following options I am aware of that aren't on your list:
1) If you responded to Remicade but lost response it is not uncommon to re-do the loading doses, shorten the span to as few as 4 weeks and increase the dose (I know one person who's on triple dosing).
2) Trying the immune modulators - 6-MP and Methotrexate. Sometimes these turn out to be the best meds. Drawback is they take time, 6-MP longer than Methotrexate.
3) Other anti-TNF alpha meds that are not often used but work for some people include thalidomide (strictly controlled and good for a year or two only), tacrolimus are two I know are out there
4) clinical trial?? there are a number currently
open that are testing a variety of treatment options including rifaximin
www.clinicaltrials.gov/ct2/results?term=crohns&recr=open5) TPN as someone else suggested; exclusive enteral nutrition is usually most helpful for small intestine disease but does sometimes work for people with mostly colonic disease.
All that said, there are a lot of CDer's walking around without their colon who are very glad it's gone. You can actually live pretty well without it I hear.
Hope you get feeling better soon.
