i just watched a video from the mayo clinic about the colonoscopy. it shows just the colon area being examined. ( i never realized how long it is) whats the difference if any from the probing the anus to swallowing this little camera? i tried to look up where the patient swallows this tiny camera but was unsucesful. I mean i cant imagine they put one in the top and another in the bottom lol. anyone found a video where they do this? i think i am going to be scheduled in August. john
