Welcome to HW.com!! I too have CD. I have had multiple resections prior to my permanent ileostomy, and therefore, I too have a lot of scar tissue/adhesions. My CD kept coming back after the resections. Fortunately, no hint of it since my perm. ileo in 1984.
Remicade was even born yet when my surgeon made the decision that meds were not doing their job for me. Of course, about the only thing that even made the smallest difference for me was prednisone - oral, enemas, suppositories --- all at the same time. I pushed my luck and waited until I was unable to keep anything down to have my surgery and was pretty malnourished by then. My recovery took longer than average because of the shape I was in prior to surgery.
Please do your research and ask these questions to get input. I agree with Ohio, it is your body and you have control over what you wish to put into it.
