Non-Visceral Structures of the Abdomen - Omentum

HIDE
PrevNext

0:00

So in terms of the omentum, let's talk about its structure.

0:03

It's actually a little bit more complicated than one might expect. So

0:06

the mentor actually fuse peritoneal folds

0:09

that attach the abdominal organs to one

0:12

another

0:13

You know, it's also called the apron of the abdomen.

0:16

So when it comes to the grad omentum, it's attached to the greater

0:19

curvature of the stomach as well as a transverse colon

0:22

and descends inferiorly over the intestines IE, hence

0:25

it being termed an apron.

0:27

The less momentum is attached to the Lesser curvature

0:30

of the stomach.

0:31

And the liver so what's the function of the great

0:34

momentum? Well, it's called the policeman of the admin Walling

0:37

off areas of disease. And when we think about sort of

0:40

peritoneal carcinomatosis is actually one of those first sites

0:43

in peritual carcinomatosis, when we

0:46

see actually seeding and implants within the abdomen the

0:49

less abdomen forms the anterior borders of

0:52

the epiploric foramen of Winslow and

0:55

then we have it separates the greater and the less of sacs of

0:58

the peritoneum. So the momentum may be subdivided into

1:01

constituent ligaments and this is sort of on the

1:04

origin of really sort of understanding what it entails. So

1:07

the last momentum includes the hepato gastric

1:10

ligament from the liver to the

1:13

stomach, they are part of duodenal ligament from liver

1:16

to the duodenum when it comes to the greater romantic.

1:19

It has a few ligaments attachments the

1:22

gastro-frenic diaphragm the stomach

1:25

gastrocolic.

1:27

Colon stomach the gastro splenic

1:30

ligament stomach the spleen splenorenal the

1:33

spleen to the kidney in the

1:36

frontal splenic ligament from the diaphragm to

1:39

the spleen.

1:42

So when we think about the greater omentum, it actually contains and

1:45

a supply where the right and left gastroenter arteries

1:48

interestingly. The lasso momentum actually is sort of

1:51

a little conduit for the right and left gastric arteries,

1:54

which are particularly a note and run along the

1:57

Lesser curvature of the stomach.

2:01

The hyperduino ligament of the lessomentum contains

2:04

the portal Triad which includes hepatic artery

2:07

proper the common bile duct. And of course the portal

2:10

vein.
