Are you sure you had all of your colon removed, and it wasn't just a partial? I had a proctocolectomey which is removal of almost all your large intestine and the rectum, and then I had to have an ileostomy bag for 3 months while the new hookup inside of me healed. If you don't have a colon, you can't have a colonoscopy.. It's impossible. I have a procedure every year where they go in and look at the hook up but that's called a sigmoidoscopy, and they make sure that there's no cancer on the tiny bit of large intestine I still have, which is probably an inch! Is it possible this doctor doesn't understand you had a complete colectomy? Did you just ask them straight out how are you supposed to do that when I have no colon? I'd be a little concerned if I were you also especially if they are recommending two doctors to do a colonoscopy on a colon that doesn't exist.
I hope things get figured out!
