Okay, so we've seen an umbilical hernia, and that
0:03
was quite nice and very easy to diagnose.
0:05
But there are number of other types of
0:06
hernias throughout the abdominal cavity,
0:09
many of which have dead white guy names
0:11
again, and you have to know many of them.
0:13
But we're gonna talk about the groin hernias.
0:16
So the overarching umbrella here is groin hernias,
0:19
and here are three patients with groin hernias.
0:22
Can you decide which one has the
0:24
greatest risk for bowel strangulation?
0:26
Take a moment and look at all three.
0:30
Okay, so let's look at how we analyze groin hernias.
0:34
The first thing I do when I see a groin
0:36
hernia is I draw a horizontal line from
0:38
the lateral aspect of the symphysis pubis,
0:41
that's referred to as the pubic tubercle.
0:43
Once I draw that horizontal line,
0:45
I decide if the hernia comes out anterior
0:47
or posterior to that horizontal line.
0:51
If the patient has a hernia that comes out
0:54
anterior, it is going to be an inguinal hernia.
0:57
You have both your indirect
0:58
and direct inguinal hernias.
1:00
The posterior to this horizontal line
1:03
are your femoral hernia and your obturator hernia.
1:06
The femoral hernia will be anterior to the
1:08
pectineus muscle, but don't worry, we're gonna
1:10
go through this again, and the obturator hernia
1:12
here will be posterior to the pectineus muscle.
1:15
So let's go into the groin
1:19
inguinal hernias — so groin hernia, inguinal
1:21
hernias — both your direct and your indirect hernias.
1:24
So your indirect hernia,
1:25
this is the classic image of Hesselbach’s
1:28
triangle that you may have learned during
1:30
your surgical rotation in medical school.
1:31
But guess what?
1:32
It all comes back to you.
1:33
You don't get to forget anything besides renal
1:36
homeostasis, which you don't have to know anymore.
1:38
Lucky you.
1:39
I condoed that personally. Anyway, so I digress.
1:43
So if the bowel comes out lateral, the landmark here
1:46
is the inferior epigastric vasculature, the lateral
1:50
margin of the rectus muscle, and the inguinal ligament.
1:53
If the hernia comes out lateral to the
1:55
epigastric vasculature and goes down the
1:57
inguinal ligament, that is an indirect hernia,
2:00
as opposed to a direct hernia, which will be
2:02
medial to the epigastric vasculature
2:05
and come anterior to that.
2:07
So this would be the indirect,
2:08
and this would be the direct hernia.
