This is Pediatrics week 2 case number
0:03
one and the diagnosis for this case is
0:06
necrotizing enterocolitis.
0:09
Now as you know, necrotizing enterocolitis or neck is
0:12
a bacterial infection of the bowel.
0:15
Typically the small bowel of newborns and
0:18
especially children born
0:21
prematurely. So it's those patients,
0:24
who are
0:27
Quite premature whose bowel is especially at
0:30
risk and this is a KUB radiograph, which
0:33
is been performed on a four week old.
0:36
And we can see that there's a suction catheter
0:39
that courses down the midline and terminates over the left
0:42
Hemi abdomen but more importantly we can
0:45
see multiple areas of Interest throughout
0:48
these Loops of bowel in
0:51
the left Hemi abdomen.
0:53
As you can see me outlining here, but also over in
0:56
the right Hemi abdomen and what we're
0:59
actually seeing are abnormal Lucy
1:02
some of which appear almost bubbly and
1:05
some of which are quite linear and follow the expected Contour
1:08
of the bowel wall.
1:10
And this is air but it's not intraluminal air
1:13
as we would like to see in bowel. It
1:16
is submucosal air. So the infection by
1:19
the bacteria into the bowel wall causes necrosis
1:22
of the bow wall and
1:25
air dissects under the mucosal layer
1:28
of the bowel.
1:29
And into the muscularis and
1:32
into eventually the mesentery of
1:35
the bowel and that gas can finally dissect into
1:38
the veins of the mesentery all
1:41
the way back through the mesentery veins to the portal vein
1:44
and you can find loosen sees in
1:47
the liver of portal Venus gas. This is
1:50
a very concerning finding and when you have extensive linear
1:53
Lucy's throughout the bowel as we see
1:56
here that bowel is at risk for perforation perforation,
1:59
of course would give us free intra peritoneal
2:02
air and here we have a lateral decubitus film
2:05
a left lateral decubitus film. We
2:08
perform radiographic Imaging in this position in
2:11
the hope that air will rise to the non-dependent side of
2:14
the abdomen and would reveal itself. In this
2:17
case. We don't see free and prepare to Neil air, but this patient is
2:20
at high risk, and we need to continue to
2:23
monitor them radiographically to evaluate for
2:26
that as soon as we see it. Most likely they'll be
2:29
going
2:29
Surgery because they have necrotic bowel.
2:32
Even on this lateral decubitus film. We can see abnormal
2:35
lucencies circumferentially surrounding
2:38
this piece of bowel here
2:41
and elsewhere in the abdomen on both sides.
2:45
So the key things to be aware of is Are there specific radiographic
2:48
signs of necrotizing enterocolitis submucosal
2:51
pneumatosis portal
2:54
venous gas, or worst of all perforated bowel
2:57
leading to free and repair tineal air.
3:00
But just because we don't have those findings doesn't
3:03
mean the patient doesn't have necrotizing intro
3:06
colitis. So the thing to be mindful of is the
3:09
bowel gas pattern. Is it normal? Does it
3:12
look abnormally distended to the loops of bowel hold their
3:15
same exact position and shape over multiple days.
3:18
These are concerning signs not quite specific
3:21
signs. So what we see here is the
3:24
neumatosis intestinalis specific for this
3:27
infection, and that's the end of the case.
