Peritoneal Pouches, Recesses, Spaces, and Gutters Flashcards
- Lies behind the stomach and the lesser omentum.
- It extends upward as far as the diaphragm and downward between the layers of the greater omentum.
Lesser sac
The left margin of the sac is formed by the spleen and the gastrospinic momentum and splenicorenal ligament.
The right margin opens into the greater sac (the main part of the peritoneal cavity) through the ______________ or ______________.
Lesser sac
True or false.
The opening into the lesser sac (epiploic foramen) has the following boundaries:
Anteriorly: free border of the lesser omentum, the bile duct, the hepatic artery, and the portal vein.
Posteriorly: inferior vena cava
Superiorly: caudate process of the caudate lobe of the liver
Inferiorly: first part of the duodenum
True
In duodenal recesses, close to the duodenogenal junction, there may be four small pocket like pouches of peritoneum called?
- Superior duodenal recesses
- Inferior duodenal recesses
- Paraduodenal recesses
- Retroduodenal recesses
In cecal recesses, folds of peritoneum close to the cecum produced three peritoneal recesses called the?
- Superior iliocecal recesses
- Inferior iliocecal recesses
- Retrocecal recesses
This is situated at the apex of the inverted, v-shaped root of the sigmoid mesocolon; it’s mouth opens downward.
Intersigmoid recess
This spaces lie between the diaphragm and the liver on each side of the falciform ligament.
Right and left anterior subphrenic spaces
Lies between the right lobe of liver, the right kidney, and the right colic flexure.
Right posterior subphrenic space
This space lies between the layers of the coronary ligament and is therefore situated between the liver and the diaphragm.
Right extraperitoneal space
This lie on the lateral and medial side of the ascending and descending colons.
Paracolic gutters
True or false.
The subphrenic spaces and the paracolic gutters are clinically important because they may be sites for the collection and movement of infected peritoneal fluid.
