Thanks everyone for your input.
Beave, Is Imuran, the same as 6mp ? If yes then, yes he was at the correct level. Dr tested it every month.
His original scopes showed his esophagus and colon were in pretty bad shape but a year later everything is clear accept the caecum.
Is there another name for the caecum as I have never read anyone mentioned that area before.
The 2 Drs that we have seen are both great but have opposite schools of thought. 1 is top down and the other is bottoms up.
I am beginning to see that neither is right or wrong.
My next question is once you start Remicade and hopefully achieve remission via blood, stools and scope, do you stop taking Remicade?
Imuran (azathioprine) is not exactly the same as 6mp, but it's very closely related. Imuran gets metabolized by the liver into 6mp (and then on to other molecules). So they're practically equivalent. Taking either one has the same effects for the majority of people (some exceptions seem to to tolerate one better than the other for reasons not understood).
The cecum is right near the juncture of the colon and small intestine - a very common area for Crohn's disease to present itself. The ileocecal valve - the "doorway" that connects the small intestine to the colon - is right next to the cecum and a commonly affected area.
You are right that the two schools of thought both have merit. The key is not to follow either all the time, but instead to do what is dictated by your son's individual condition, disease severity and activity, growth rate, and response to medications.
Once you start Remicade, assuming it's working, you stay on it as long as you tolerate it and get benefit from it. Stopping it will often lead to the disease coming right back; what's more, stopping it and restarting it increases odds of having a reaction to it.
