Is omental foramen the same as epiploic foramen?

Anatomical terminology

In human anatomy, the omental foramen (epiploic foramen, foramen of Winslow after the anatomist Jacob B. Winslow, or uncommonly aditus; Latin: Foramen epiploicum), is the passage of communication, or foramen, between the greater sac (general cavity (of the abdomen)), and the lesser sac.

How many types of omentum are there?

There are two omenta, the greater omentum and the lesser omentum. The greater omentum attaches the stomach to the transverse colon. The lesser omentum attaches the stomach and the duodenum to the liver. The omenta are derived from the embryological ventral and dorsal mesenteries.

What is the epiploic foramen?

The epiploic foramen (also called the foramen of Winslow) is a passage between the greater sac (peritoneal cavity proper) and the lesser sac (omental bursa), allowing communication between these two spaces.

What is the Gastrosplenic omentum?

Anatomical Parts

The gastrosplenic ligament (ligamentum gastrosplenicum or gastrolienal ligament) is part of the greater omentum. The gastrosplenic ligament is made of peritoneum that connects the greater curvature of stomach with the hilum of the spleen. Contains: Short gastric vessels and left gastro-epiploic vessels.

What purpose does the omentum serve?

What causes epiploic foramen entrapment?


What is the omentum in the human body?

The Omentum is a large flat adipose tissue layer nestling on the surface of the intra-peritoneal organs. Besides fat storage, omentum has key biological functions in immune-regulation and tissue regeneration.

What organs does the omentum cover?

The omentum is the fatty tissue that secures the intestines and other abdominal organs in place, supplying them with blood along with physically protecting them. The omentum ("policeman of the abdomen") is a double layer of fatty tissue that covers and supports the intestines and organs in the lower abdomen.

Can omentum be removed?


What goes through omental foramen?

The posterior vena cava runs through the omental foramen. The purpose of the omental foramen is to connect the peritoneum's two sacs.

What is the lesser omentum?

The lesser omentum, also called the 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).

Where is retroperitoneal space?

The retroperitoneum is an anatomical space located behind the abdominal or peritoneal cavity. Abdominal organs that are not suspended by the mesentery and lie between the abdominal wall and parietal peritoneum are said to lie within the retroperitoneum. Several individual spaces make up the retroperitoneum.

What drains blood from the liver?

The hepatic veins are the veins that drain de-oxygenated blood from the liver into the inferior vena cava. There are usually three upper hepatic veins draining from the left, middle, and right parts of the liver.

Is epiploic appendagitis life threatening?

Individuals with epiploic appendagitis have a relatively positive outlook. Although they may experience intense abdominal pain, this condition is self-limiting and does not usually cause complications.

How long can epiploic appendagitis last?

The inflammation may cause secondary thickening of the parietal peritoneum, and the colon wall may be inflamed as well [2]. Although the patient's clinical symptoms usually resolve within 2 weeks, CT findings can last for as long as 6 months after the episode, showing some residual soft tissue attenuation [2].

Is epiploic appendagitis rare?

It's relatively rare and has only recently become more easily noticed in the medical world. Because it's not well known, it's often misdiagnosed and confused with other conditions that also cause severe stomach pain. Epiploic appendagitis is relatively understudied, and research is in early stages.

Why do they remove the omentum?

In animals, removing the omentum impacts on the survival of free intraperitoneal malignant cells and there by reduces the rate of local recurrence[72,73]. Because of these observations, the omentum is frequently removed as part of resections for malignancies of various intra abdominal organs[74].

Do you gain weight after omentum removal?

Omentum drives obesity progression through leptin resistance mediated by C-reactive protein, Interleucin (IL)-6 and high lipolysis activity. Omentum removal reversed immediately the increased plasma levels of CRP and IL-6 and gradually food intake, weight gain, and features of MS in diet-induced-obesity.

What happens if your omentum is removed?

Because removal of the omentum can result in surgical morbidity and longer-term problems with metabolism and peritoneal immunosurveillance, scientists are looking for ways to spare the omentum during treatment for ovarian cancer.
