This was a one day old female who had abdominal distension
0:04
and failure to pass meconium.
0:06
We have an abdominal radiograph with an enteric tube
0:08
with the tip projecting over the leftward aspect
0:10
of the gastric body.
0:12
Um, and then when we draw our line along the, uh, equator
0:16
of this abdomen, we have dilated bowel loops both above
0:20
and below the equator.
0:21
So this is a distal BGAs obstruction pattern.
0:24
So this patient will go on to contrast enema
0:26
as the next step in the workup of, uh,
0:29
of why there is a distal, um,
0:31
distal obstructive BGAs pattern.
0:33
The left lateral acute dispute doesn't add much.
0:35
It just shows that there's no pneumoperitoneum.
0:38
Obviously, we don't see pneumatosis
0:39
or portal venous gas in this infant either.
0:43
So this patient came next to the fluoroscopy suite
0:45
to undergo contrast enema.
0:47
We don't have a scout on this patient
0:49
because that x-ray was immediately preceding this.
0:52
So we use that x-ray as our scout image
0:54
for this contrast enema.
0:55
So we have placed a, a catheter in the rectum.
0:58
We have injected, um,
1:00
or instilled by gravity drip,
1:02
a dilute water soluble contrast.
1:04
Um, here is our lateral rectum filling shot.
1:07
We want our rectum to be larger than our sigmoid ratio, um,
1:11
which maybe you can see better on this,
1:13
uh, later filling image.
1:14
So we have a normal rectal sigmoid ratio
1:17
where the rectum is larger than the caliber
1:19
of the sigmoid colon, but the abnormality here is
1:23
that the rest of the colon is pretty diminutive.
1:26
So, uh, uh, normal rectum, somewhat normal sigmoid,
1:29
but the rest of the descending colon is pretty small in
1:32
caliber until we get to the level of the splenic flex.
1:36
Once we get to the level of the splenic flexure, the caliber
1:38
of the colon is more normal in appearance.
1:41
So this, this appearance of normal caliber rectum
1:44
with diminutive remainder of the rest
1:45
of the descending colon is really classic for
1:49
functional immaturity of the colon
1:50
or small left colon syndrome.
1:53
Um, it's the same diagnosis,
1:54
just two different names for the same thing.
1:57
So the good news is, um,
1:58
this contrast ENA enema is probably not only diagnostic,
2:02
but it's probably therapeutic.
2:04
Um, the water soluble contrast is a little bit hyperosmolar.
2:07
It draws water from the body into the colon to help, um,
2:11
that meconium pass, uh, pass through that distal colon.
2:16
And, and whatever other content is in, is in the,
2:19
uh, is in the colon.
2:21
This is a, a diagnosis that is more common in infants
2:24
of diabetic mothers
2:25
and infants who, uh, the, the mother was treated
2:28
with magnesium prior to, um, delivery.
2:31
And it's usually a self resolving, um, abnormality,
2:36
especially after a contrast enema to help things get moving.
2:39
So no surgical, uh, treatment or other treatment is needed.
2:44
Um, they just, uh, will continue
2:46
to clinically monitor this patient to ensure that the, um,
2:49
stooling becomes normal after this enema.
