Why is the epiploic foramen important?

Anatomical Parts

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

What is the clinical significance of the lesser sac and epiploic foramen?

What is the Clinical significance of the lesser sac and epiploic foramen? CLINICAL SIGNIFICANCE: This is the site of internal herniation and strngulation of part of intestine into the lesser sac. Surgery should be done from the other side (into the sac), not touching the porta hepatis.

What causes epiploic foramen entrapment?

The epiploic foramen is located in the right dorsal abdomen and is bordered by the vena cava, hepatic portal vein, liver and pancreas. Most incarcerations are caused by small intestine passing from the left side of the abdomen through the epiploic foramen to the right side of the abdomen.

Where is the epiploic foramen?

The epiploic foramen (also called the foramen of Winslow) is a passage between the greater sac (peritoneal cavity proper) and the lesser sac (omental bursa), allowing communication between these two spaces.

What is significance of foramen of Winslow?

The clinical significance of Winslow’s foramen is 2-fold. First, it serves as a site for an internal hernia. Hernias in the foramen of Winslow are exceedingly uncommon. As with most internal hernias, the presenting symptoms are non-specific and are generally those of intermittent bowel obstruction.

What forms the boundaries of epiploic foramen?

Epiploic foramen/Foramen of Winslow:
Its boundaries are: Anteriorly: free edge of lesser omentum containing within its layers: Bile duct (in front and to the right) Hepatic artery (in front and to the left0.

What is the clinical significance of the lesser sac?

The lesser peritoneal sac is an intricate anatomic region involved in many disease processes and is a significant conduit for the spread of disease within the peritoneal cavity [10]. CT is considered the modality of choice for imaging the omental bursa [11].

What lies posterior epiploic foramen?

As the portal vein is the most posterior structure in the hepatoduodenal ligament, and the inferior vena cava lies under the posterior wall, the epiploic foramen can be remembered as lying between the two great veins of the abdomen.

What is foramen of Winslow hernia?

DISCUSSION. Foramen of Winslow hernia can be defined as peculiar variant of internal abdominal hernia, since it is a normal peritoneal orifice kept closed by normal intra-abdominal pressure that may be permeated by the intra-abdominal viscera [3].

What are the boundaries of foramen of Winslow?

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.

• Posteriorly: Inferior vena cava covered by peritoneum.
• Superiorly: Caudate process of liver.
• Inferiorly: 1st part of duodenum.

What is the difference between lesser sac and greater 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. Usually found in mammals, it is connected with the greater sac via the omental foramen or Foramen of Winslow.

What causes fatty appendix?

What Causes Epiploic Appendagitis? Small sacks of fat sit above your colon and large intestine. Appendagitis happens when the blood flow to these sacks is cut off or restricted. This may happen if there is inflammation of the tissue around the sacks.

Where is a Spigelian hernia located?

Spigelian hernia occurs through slit like defect in the anterior abdominal wall adjacent to the semilunar line. Most of spigelian hernias occur in the lower abdomen where the posterior sheath is deficient. The hernia ring is a well-defined defect in the transverses aponeurosis.

What is a Paraduodenal hernia?

Paraduodenal hernia is a rare congenital anomaly that arises from an error of rotation of the midgut. The duodenum and the small intestine become trapped in a sac which is lined by the peritoneum, behind the mesentery of the colon, either to the right or left of the midline.

What is the boundaries of the epiploic foramen of Winslow?

Why is Rectovesical pouch important?

Clinical significance
When a man is upright or supine, the rectovesical pouch is the lowest part of his peritoneal cavity. Because of this, peritoneal fluid and other fluids that enter the peritoneal cavity, including ascites, blood and pus, tend to collect in this pouch.

What does epiploic mean in Latin?

The adjectival term [epiploic] arises from the Greek term [επίπλουν] (pronounced “epiploun”) which is synonymous with the Latin term [omentum], referring to two abdominal peritoneal membranes, the lesser omentum and the greater omentum.

What is epiploic fat?

INTRODUCTION. Epiploic appendages are normal outpouchings of peritoneal fat on the anti-mesenteric surface of the colon. Epiploic appendagitis is a benign and self-limited condition [1,2]. Inaccurate diagnosis can lead to unnecessary hospitalizations, antibiotic therapy, and surgical intervention [3-6].

What is an epiploic appendix?

Epiploic appendages (or appendix epiploica, plural: appendices epiploicae) are peritoneum-lined protrusions of subserosal fat that arise from the surface of the large bowel.

What is the most common cause of a spigelian hernia?

Like other hernias, the spigelian type is mainly caused by an opening or a weakness in the abdominal wall. Other common causes include: Long-standing medical conditions that increase abdominal pressure, like chronic coughing, liver cirrhosis with fluid collection (ascites), pregnancy, and obesity.

Why is it called a spigelian hernia?

What is a spigelian hernia? A spigelian hernia is a hernia through the spigelian fascia or layer of tissue that separates two groups of abdominal muscles. The muscles are called the rectus muscles and the lateral obliques. This type of hernia is also sometimes called a lateral ventral hernia.

How common is Paraduodenal hernia?

Paraduodenal hernias (PDH) are rare congenital anomalies secondary to rotational midgut errors and failure of mesenteric fusion with the parietal peritoneum. Internal hernias account for 0.2 to 0.9% of all cases of intestinal obstruction; of these, 30-53% are congenital paraduodenal hernias.
