Yes, I recently had a colonoscopy, my dr. Said I had a narrowing to small to get the scope through. 1 polyp was removed. Now he wants me to have a barium enema done to evaluate the left descending colon. I have heard horror stories about this procedure. My mother in law had this done and it set up like cement . This was several years ago 2006. Have they made progress doing this procedure? Is there an alternative to this.
