lesser omentum

It is sometimes considered part of the lesser omentum.

The other is the lesser omentum that extends between the stomach and the liver.

In some cases, the following ligaments are considered part of the lesser omentum:

Evacuating, Rourke inspected the stomach wall between the leaves of the greater and lesser omentum.

She gave him a few seconds to sponge the wound; then she reached in and tore apart the lesser omentum.

Its boundary on the right is made by the epiploic foramen and lesser omentum.

The lesser omentum (or gastrohepatic) is attached to the lesser curvature of the stomach and the liver.

Hepatoduodenal ligament (lesser omentum)

Anatomically, the lesser omentum is divided into ligaments, each starting with the prefix "hepato" to indicate that it connects to the liver at one end.

It is demarcated anteriorly by the quadrate lobe of the liver, the stomach, lesser omentum and gastrocolic ligament.

Between the layers of the lesser omentum, where they are attached to the stomach, run the right and left gastric arteries, as well as the gastric veins.

These include the paraumbilical veins as well as veins of the lesser omentum, falciform ligament, and those draining the gallbladder wall.

The lesser omentum is formed, by a thinning of the mesoderm or ventral mesogastrium, which attaches the stomach and duodenum to the anterior abdominal wall.

At the right border of the lesser omentum, the two layers are continuous, and form a free margin which constitutes the anterior boundary of the epiploic foramen.

The hepatoduodenal ligament is the portion of the lesser omentum extending between the porta hepatis of the liver and the superior part of the duodenum.

The cranial part of the lesser omentum (omentum minus) is formed by the hepatogastric ligament (ligamentum hepatogastricum), extending between the liver and stomach.

The posterior layer of the coronary ligament is reflected from the lower margin of the bare area and is continuous with the right layer of the lesser omentum.

Where the anterior surface of the pancreas joins the neck there is a well-marked prominence, the tuber omentale, which abuts against the posterior surface of the lesser omentum.

It is invested by the peritoneal folds of the lesser omentum within a fissure on the inferior surface of the liver between the caudate and main parts of the left lobe.

The lesser omentum is extremely thin, and is continuous with the two layers of peritoneum which cover respectively the antero-superior and postero-inferior surfaces of the stomach and first part of the duodenum.

The Hepatocolic ligament is an occasional fold of peritoneum that extends from the right side of the lesser omentum and passes from the lower surface of the liver near the gallbladder to the hepatic flexure.

Between the two layers of the lesser omentum, close to the right free margin, are the hepatic artery, the common bile duct, the portal vein, lymphatics, and the hepatic plexus of nerves-all these structures being enclosed in a fibrous capsule (Glisson's capsule).

By the subsequent growth of the liver this leaf of mesoderm is divided into two parts, viz., the lesser omentum between the stomach and liver, and the falciform and coronary ligaments between the liver and the abdominal wall and diaphragm.

One long branch of it runs from the lesser curvature or parallel to it in lesser omentum as far as the pyloric antrum to fan out into branches in a way like the digits of a crow's foot to supply the pyloric antrum and the anterior wall of pyloric canal.

The surface is almost completely invested by peritoneum; the only parts devoid of this covering are where the gall-bladder is attached to the liver, and at the porta hepatis where the two layers of the lesser omentum are separated from each other by the bloodvessels and ducts of the liver.
