Hi Carrie,
Welcome to the board. Often, IBS is the diagnosis handed out if the GI doc does not take biopsies during a colonoscopy exam, since the symptoms of IBS and MC are rather similar. NSAIDS are one of the known triggers for MC, so I would suspect that there is a very good chance that he has MC, rather than IBS.
As you may know, cholestramine is a bile acid sequestrant, and it is sometimes helpful following gallbladder removal. Several members here have tried it, but I'm not aware that anyone was able to achieve remission of their MC symptoms by using it.
Here is a past discussion about bile acids. There are two links because the discussion was continued into the second link:

For most people, a diet that excludes all of their food intolerances will bring relief of symptoms. For a small percentage of severe cases, a corticosteroid is also needed, in order to achieve remission. Entocort is usually the most practical medication to use, though a few GI docs prescribe Prednisone, which has more side effects, and carries an increased risk of drug dependency. Usually, the dosage rate of the medication can be slowly diminished after remission is achieved, and for most MCers, it can be completely eliminated, and remission maintained on diet alone. Of course, some members prefer to continue to take a med, and not stay on a strict diet, but often they have be careful to restrict certain foods in their diet, anyway.

P S You may have noticed that this is an ad-fee site, and of course, discussion board admins and moderators have to constantly be on the lookout for spammers. Please don't be offended, but to be honest, the user name you selected, looks so much like a plug for a website, that I almost deleted your membership without reading your post. I'm glad I didn't. Would it be asking too much to ask that you change it to something that doesn't look like a plug for a website? Just dropping the "Online" part would make me a happy camper. That way we won't be sending the wrong signal to all the spammers out there. LOL. You can change it in your profile. Normally, user names cannot be changed, but I have activated an option that will allow you to change it. Thanks.
