Hi. My little brother came to me today to ask about a barium enema which he has been scheduled for in two weeks time. He has never been hospitalized before and other than regular visits to the doctor has never had to have medical tests at all. Unfortunately I wasn't really able to tell him much other than what he already knew. Can anyone with experience of these tests give me some advice as to what he can expect. Is it going to hurt? How long will it take? Who will be in the room?
