If these structures rupture they may leak into the lesser sac.

The lesser sac being a potential space, the fluid collects here preferentially.

It forms part of the anterior wall of the lesser sac.

"To open the lesser sac of the stomach."

In mammals, it is not uncommon for the lesser sac to contain considerable amounts of fat.

The lesser sac (or omental bursa), represented in blue.

The lesser sac is embryologically formed from an infolding of the greater omentum.

The lesser sac is divided into two "omenta":

Superiorly, it is continuous with the peritoneum which lines the hepatorenal pouch and, through the epiploic foramen, the lesser sac.

One of these the lesser sac is located behind the stomach and joins into the greater sac via the foramen of Winslow.

In supine patients, infected fluid from the right iliac fossa may ascend in the gutter to enter the lesser sac.

The lesser sac, also known as the omental bursa, is the cavity in the abdomen that is formed by the lesser and greater omentum.

The gastrocolic ligament is incised and the lesser sac is explored, including the posterior stomach and the anterior pancreas.

Consequently, the blind-ended sac (also called the lesser sac) formed by the dorsal mesentery is brought inferiorly, where it assumes its final position as the greater omentum.

A pancreatic pseudocyst is a circumscribed collection of fluid rich in pancreatic enzymes, blood, and necrotic tissue, typically located in the lesser sac of the abdomen.

It is connected with the lesser sac via the omental foramen, also known as the Foramen of Winslow or Epiploic Foramen.

CT scan may show esophageal wall edema and thickening, extraesophageal air, periesophageal fluid with or without gas bubbles, mediastinal widening, and air and fluid in the pleural spaces, retroperitoneum or lesser sac.

In human anatomy, the greater sac, also known as the general cavity (of the abdomen) or peritoneum of the peritoneal cavity proper, is the cavity in the abdomen that is inside the peritoneum but outside of the lesser sac.

Six weeks later, CT scanning showed a bulky pancreas and a large pseudocyst of the lesser sac, with fluid tracked down on the left side of the retroperitoneum in the anterior compartment, anterior to Gerota's fascia as far as the left iliac dossa.
