So another finding that's important to
0:02
discuss is the presence of sacculations.
0:05
And what these are, are broad-based outpouchings that
0:10
occur along the anti-mesenteric border of the bowel.
0:13
And so this is a, in this case, which
0:15
we've seen earlier, we do see a number
0:17
of areas of bowel that are dilated.
0:21
And so this area here, you can see on the mesenteric
0:24
side, it looks fairly normal, but it's really
0:27
thin and distended on the anti-mesenteric side.
0:31
You can see it a bit there.
0:32
You can see it on this, in this location,
0:34
you can see it kind of on a long sacculation
0:38
down here in the left lower quadrant.
0:40
And this is kind of the same as that differential
0:44
enhancement of the mesenteric side of bowel.
0:47
And it's a very specific finding for
0:50
chronic changes of Crohn's disease.
0:53
It's really due to that chronic inflammation and areas
0:57
of shortening of the gut along the mesenteric border.
1:00
And so,
1:01
it's important to mention when you see it because
1:03
it's such a specific finding for Crohn's disease
1:06
and it's a very typical finding that we, we often see
1:09
in these, you know, severe chronic patients.
