Foramen of Winslow

Vertical disposition of the peritoneum. Main cavity, red; omental bursa, blue. (Bristle in epiploic foramen labeled at upper left.)

Foramen of Winslow is at #14.
Latin	foramen epiploicum
Gray's	subject #246 1156

In human anatomy, the foramen of Winslow (named after the anatomist Jean-Jacques Bénigne Winslow^[1]), also known as the omental foramen, epiploic foramen and foramen epiploicum (Latin), is the passage of communication, or foramen, between the greater sac, the general cavity (of the abdomen), and the lesser sac, the omental bursa.

Borders

It has the following borders:

anterior: the free border of the lesser omentum. This has two layers and within these layers are the common bile duct, hepatic artery, and hepatic portal vein.
posterior: the peritoneum covering the inferior vena cava
superior: the peritoneum covering the caudate lobe of the liver
inferior: the peritoneum covering the commencement of the duodenum and the hepatic artery, the latter passing forward below the foramen before ascending between the two layers of the lesser omentum.
