I had my gallbladder removed after diagnosis and before any resections. The old fashioned way, not laproscopicly (sp). So I have the lovely scar wrapping around my rib cage. It didn't cause any new issues with my CD. I wasn't on 6MP at the time, just prednisone, I think. It was about 18 years ago and my memory is a bit fuzzy about what drugs I was on. I might have been on flagyl too. I also had a c-section after diagnosis and before any resections. But I wasn't on any CD meds at the time. I had a no CD med pregnancy. I think the best thing you can do is trust your surgeon to tell you what you can and can't be on, and then run it by your GI. If your doctors work together and you trust them, you should be in pretty good hands.
Best wishes for a complication free surgery and a speedy recovery.
