epiploic

The peritoneal cavity gives off a large diverticulum, the omental bursa, which is situated behind the stomach and adjoining structures; the neck of communication between the cavity and the bursa is termed the epiploic foramen (foramen of Winslow).

The transverse colon, between which and the lower border of the stomach is seen the gastro-epiploic artery, formed by the splenic and hepatic arteries.

It then crosses the portal vein anteriorly and ascends between the layers of the lesser omentum, and in front of the epiploic foramen, to the porta hepatis, where it divides into two branches, right and left, which supply the corresponding lobes of the liver, accompanying the ramifications of the portal vein and hepatic ducts.

Laterally, the bursa extends from the epiploic foramen to the spleen, where it is limited by the phrenicolienal and gastrolienal ligaments.

It is first directed forward and to the right, to the upper margin of the superior part of the duodenum, forming the lower boundary of the epiploic foramen (foramen of Winslow).

—Above the transverse colon the omental bursa is superadded to the general sac, and the communication of the two cavities with one another through the epiploic foramen can be demonstrated.

The epiploic foramen (foramen epiploicum; foramen of Winslow) is the passage of communication between the general cavity and the omental bursa.

At the right border of the omentum the two layers are continuous, and form a free margin which constitutes the anterior boundary of the epiploic foramen.

It forms the upper boundary of the epiploic foramen of the peritoneum.

The omental bursa, therefore, consists of a series of pouches or recesses to which the following terms are applied: (1) the vestibule, a narrow channel continued from the epiploic foramen, over the head of the pancreas to the gastropancreatic fold; this fold extends from the omental tuberosity of the pancreas to the right side of the fundus of the stomach, and contains the left gastric artery and coronary vein; (2) the superior omental recess, between the caudate lobe of the liver and the diaphragm; (3) the lienal recess, between the spleen and the stomach; (4) the inferior omental recess, which comprises the remainder of the bursa.
