You can get scoped regularly.
Now I used to work at a GI lab at a hospital, so I've seen more people get scoped than I care to recall. It's not so fun. I'll run you through the usual procedure.
The stuff you see on TV is Katie Couric (sp) chugging her go-litely or nu-litely, and she explains how she craps profusely for a couple hours. It's not so fun. You get to the hospital, you get into your robe, you get wheeled to the waiting room, more or less. You wait for the doctor. Most doctors are always late. I tell your family that the doctor is never late, and that he must have been held up by something important. I lie. He's probably eating breakfast. So they get you in there, and the black garden hose is lubed up and, well, you know what happens from there. Only it's gross

I'd delve into what happens during, but you're asleep.
Only stuff that happens afterwards is your colon probably hasn't been properly deflated, so you fart like you can't imagine. You're a little woozy, since the doctors like for you to be nuked on versed and demerol or sublimaze (sp). It's a good time. You go home, and that's about that.
