This is basically correct, Marshalee, in fact they cant get beyond the
dec.col. at all now; but the entire colon can be quite nicely viewed-- I
have had them with and without sedation [same with endoscopic] and there
is some discomfort from the air pressure inserted to shape the colon for
a better view and things can get a little crowed in there if they turn
the scope around for a look in the other direction such as to look at the
anus from inside. There may be discomfort [moderate pain] if they snip of
suspicious tissue for analysis. They can even remove polyps with the
thing; I would imagine this would always would be under sedation. 
Afterwards, there can be quite a bit of passing of the air I mentioned
and some are embarrassed [yes, em-bare-assed]. Not everyone is thrilled
to have someone poking them around there..... but what the heck.... your
life might be worth saving..... imagine how your loved ones would
feel..... how Katie feels  about her husband not having had this
relatively simple testing.
        An interesting perspective about it all is, as some maintain,
that it ALL occurs OUTSIDE the body [except for the IV, if used]. From
the nose straight thru to the anus, is considered by some to all be
outside the body, hence, about as non invasive as you can get.
        ...as I said before:  
if you have no familial colon prob, are under 50, no symptoms of colon
prob. NO one they are responsible for/to, and no family that gives a damn
about em..... if you don't care..... you're silly.
