What is an omental bursa?
The omental bursa is a large recess of the peritoneal cavity, formed by a double-layered fold of serous peritoneum located inferiorly to the liver, posteriorly to the lesser omentum and the stomach and anteriorly to the pancreas [2].
What is Pregastric Bursa?
pregastric bursa accommodates left hepatic lobe and anterior wall of stomach; • omental bursa is situated behind lesser omentum and it is in touch with posterior stomach surface. Lesser omentum is formed by double peritoneal sheet that forms of hepatogastric ligament and hepatoduodenal ligament.
What is superior recess of lesser sac?
Recesses. Superior (hepatic) recess – between caudate lobe of liver and diaphragm. Splenic recess – between splenic ligaments and stomach. Inferior (omental) recess – between stomach and transverse colon.
What is the Supracolic compartment?
The supracolic compartment contains the liver, spleen, stomach, and lesser omentum. The infracolic compartment contains the coils of the small bowel surrounded by the ascending, transverse, and descending colon and the paracolic gutters.
What is the omental?
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.
How is the omental bursa formed?
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.
What does the Mesocolon do?
The mesocolon or mesentery of the sigmoid colon provides a major avenue for spread of disease between the abdominal cavity and the pelvis. It is directly continuous with the posterior bare area of the colon, the bare area of the rectum, and in females, the broad ligament.
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).
What is lesser sac and lesser omentum?
The lesser sac, also known as the omental bursa, is the cavity in the abdomen that is formed by the lesser and greater omentum. Usually found in mammals, it is connected with the greater sac via the omental foramen or Foramen of Winslow….

What is the omental foramen?
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.
What is omentum for?
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.
