I have no idea what that is either but I thought i'd leave some encouraging advice..
I wouldn't stress yourself out about it too much, in the end it will help you immensely (hopefully).
Doctors have definitly been known to make things out to be a lot worse than they are. I know that when I did my colonoscopy prep, the doctor said it would be hellish. HOwever, as an IBSD, I found the prep to be a walk in the park. Normal D without the pain. Boy was I suprised after hyping it up so much. Maybe you'll be pleasantly suprised (well as much as you can be when people look into parts of your body that aren't visable; ie. colonoscopy, ultrasound etc)
