- I was just about to post on my thread about my second Remicade treatment today when I saw your topic about being diagnosed with Crohn's after j-pouch surgery. Welcome to the club! I had my j-pouch installed in 2000 and in 2016 my GI diagnosed me with Crohn's. I had a different GI in a difference province also recently confirm that diagnosis. Hence, I am now on Remicade. I will go to my Remicade thread now for a quick update. All the best.
