I have had a J-pouch for 12 years. I was originally diagnosed with ulcerative colitis which confines itself ONLY to the colin. So, the fix for UC is complete removal of the colin and a J shaped internal pouch is made out of the end of the small bowel; then hooked up to the back door. Chron's, on the other hand can appear ANYWHERE in the digestive tract so a J-pouch would do no good. As a matter of fact it makes things worse by causing adhesions and exciting the rest of the gut into inflaming, which is what I'm facing now.
However, my diagnoses changed from UC to Chron's in 2005. This happens on more than one occassion and I already had the J-pouch. To make matters worse, I had to have surgery again to recover a lodged capsule endoscopy. I had to look really hard to find a surgeon that would even do it without leaving me with an ostomy since the survival rate for Chronies with J- pouches is only like 30%.
Today, I am still facing the possibly of removing the J-pouch.
I wish I still had a colin!
