Epiploic Foramen Also Called As Epiploic Foramen Is A Passage Of Communication With Greater Sac And Lesser Sac of peritoneal cavity.

It has following boarders :
  * Anterior
  * Posterior
  * Superior
  * Inferior
  * Left lateral

The anterior boarder of omental foramen have the free boarder of lesser omentum. It is the part of peritoneum stretching between the lesser curvature of the stomach and the visceral surface of the liver. 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.
When these two layers reach the lesser curvature of the stomach and the upper border of the duodenum, they join together and ascend as a double fold to the porta hepatis.
To the left of the porta, the fold is attached to the bottom of the fossa for the ductus venosus, along which it is carried to the diaphragm, where the two layers separate to embrace the end of the esophagus.
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.
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.
Most sources divide it into two parts:[1]
  * hepatogastric ligament: the portion connecting to the lesser curvature of the stomach
  * hepatoduodenal ligament: the portion connecting to the duodenum.

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).

The common bile duct (ductus...
