Can anyone tell me how the pill cam works? Do you have to retrieve the camera after it has gone through? How are pictures retrieved? Can it substitute for a small bowel barium study? In my 16 years of CD, my doc has never suggested we try this. I have a colonoscopy on Monday and am wondering if I should ask him about doing it right after, since I'll be all cleaned out. My disease is mainly isolated to the terminal ileum, where I had approximately 12 inches removed in 1999. During scopes, the doc. has always had an extremely difficult time visualizing my hookup site because of how they reattached and because of inflammation. And that means he always wants a barium study and I can't stand the barium! I would love any info. anyone can share!
