Let's keep talking about
the diagnostic test
for a patient with suspected
acute cholecystitis.
00:07
We've talked about the lab work and that
is always going to be step one. Right?
That's what we're
going to look at first
as that lab work comes back and
we see things that are abnormal,
The next thing that will
be ordered in the process
is likely an ultrasound
of the gallbladder.
00:21
Now, this is the most common tests performed
to evaluate gallbladder abnormalities,
want to know why?
Well, here's what it's got going for it.
00:30
It's a non-invasive test.
00:32
Look at the graphic
I have for you there.
00:34
You see that it's a wand,
that's about what it involves
a wand and some gel.
00:40
Now it's connected to a
very sophisticated machine
and is run by someone who is
highly educated to do that.
00:46
But from the
patient's perspective,
it is non-invasive of
simple straightforward test
little bit of gel little bit
of wand you're good to go.
00:56
So it's not hard for the patient to undergo
one of these tests or even uncomfortable.
01:01
But what we get our pictures of
the gallbladder and the bile ducts.
01:07
So go ahead and
underline that for me,
gallbladder and bile ducts.
01:11
You can see why this
would be helpful.
01:14
We notice that your
lab work is abnormal.
01:17
We've got elevated lab
work that tells us...
01:20
that hepatobiliary duct system
is just not draining well,
this abdominal ultrasound is going
to give us some actual pictures,
so inflammation and
indications of bile blockage
can actually be visualized.
01:34
That's if the abdomen is normal
or if the patient doesn't have some
other uncomfortable circumstances.
01:41
Let me tell you what I mean.
01:43
If the patient is obese
and has a large amount of
adipose tissue in
their abdominal wall
may be difficult to get
really clear pictures.
01:51
Also if the patient has a lot
of flatulence in the intestines
that they also
make it difficult.
01:58
So what do we do?
Well the order CAT
scan or an MRI?
So this seems like a
logical transition.
02:05
We've looked at lab work.
02:07
Now, we've talked about
an abdominal ultrasound,
if that doesn't work
or it's not clear
either because the patient's
abdomen is difficult to visualize.
02:15
Well, I've got a lot
of extra gas in there.
02:17
Then we go to the next step,
a CT scan which you hear us
call a CAT scan or an MRI.
