The free border of the lesser omentum between the porta hepatis and the duodenum contains the hepatic artery, the portal vein, the common bile duct, lymph glands, lymph vessels, and nerves, forming the hepatic hilum.
D’autre part, What does the lesser omentum cover?
The lesser omentum (small omentum or gastrohepatic omentum) is the double layer of peritoneum that extends from the liver to the lesser curvature of the stomach (hepatogastric ligament) and the first part of the duodenum (hepatoduodenal ligament).
De plus, What is in the lesser omentum?
The lesser omentum consists of two ligaments: medially located hepatogastric ligament, and laterally located hepatoduodenal ligament. The hepatogastric ligament connects the lesser curvature of the stomach to the visceral surface of the liver.
Ensuite, What is the omentum and what is its function?
The omentum. It’s a curtain of fatty tissue that hangs down from our stomach and liver and wraps around the intestines, and is known to play a role in immune responses and metabolism, although exactly how that happens is only dimly understood.
What is omental bursa?
The omental bursa or lesser sac is a hollow space that is formed by the greater and lesser omentum and its adjacent organs. It communicates with the greater sac via the epiploic foramen of winslow, which is known as the general cavity of the abdomen that sits within the peritoneum, but outside the lesser sac.

Development. The lesser omentum is composed of two peritoneal ligaments that extend from the lesser curvature of the stomach and duodenal bulb to the liver, the gastrohepatic, and hepatoduodenal ligaments, respectively.
What does the greater omentum cover?
The greater omentum attaches the stomach to the transverse colon. The lesser omentum attaches the stomach and the duodenum to the liver. The greater omentum is derived from the dorsal mesentery, while the lesser omentum originates from the ventral mesentery.
Is the pancreas in the lesser sac?
The lesser sac is situated behind the stomach and in front of the pancreas. The caudate lobe invaginates the lesser sac. Below the liver, the stomach, transverse colon, and small intestine are seen in section. The greater omentum and transverse mesocolon are fused posteriorly.
What is the lesser omentum made of?
The lesser omentum consists of two ligaments: medially located hepatogastric ligament, and laterally located hepatoduodenal ligament. The hepatogastric ligament connects the lesser curvature of the stomach to the visceral surface of the liver.
What is contained in the lesser sac?
Development. The lesser omentum is composed of two peritoneal ligaments that extend from the lesser curvature of the stomach and duodenal bulb to the liver, the gastrohepatic, and hepatoduodenal ligaments, respectively.
Can the greater omentum be removed?
A supracolic omentectomy, or total omentectomy, removes the entire omentum. A partial omentectomy removes part of the omentum. An omentectomy is typically performed in combination with other treatments such as a hysterectomy or a salpingo-oophorectomy.
