Just to bring this situation up to date. My pouch specialist advised me today that it is quite possible that the narrowing of my bowel just above the J Pouch is not due to Crohn's disease. He thinks that one possible explanation is that there is an insufficient blood flow to this area of my bowel as a result of my surgery or surgeries, which would explain why the situation has not really gotten worse and has shown no change since being detected in 2008. He also thinks it could be a result of inflammation from bacterial overgrowth. In any event he wants me to try and reduce my antibiotic dosages while continuing on the Entocort, since the rotation of antibiotics one week and no antibiotics the next has not worked (as of my second attempt to get through that regimen last week). He wants to see me back for another scope in June 2013 (1 year mark) at which time the narrowing of the bowel will be reassessed.
