What does Supracolic mean?
The supracolic compartment contains the liver, spleen, stomach, and lesser omentum. The infracolic compartment contains the coils of small bowel surrounded by ascending, transverse, and descending colon and the paracolic gutters.
What are the Extraperitoneal organs?
Which organs lie extraperitoneal? The kidneys, and the large vessels – the aorta and the inferior vena cava- are the main (primary) retroperitoneal organs. In the left image, the dashed blue line indicates the peritoneum. The bladder, the cervix of the uterus and the last part of the rectum lie subperitoneal.
What are the Mesenteries?
The mesentery is a fold of membrane that attaches the intestine to the abdominal wall and holds it in place. Mesenteric lymphadenitis is an inflammation of the lymph nodes in the mesentery.
Where is the Supracolic compartment located?
Supracolic compartment – lies above the transverse mesocolon and contains the stomach, liver and spleen.
What is a Supracolic omentectomy?
A supracolic omentectomy, or total omentectomy, removes the entire omentum. A partial omentectomy removes part of the omentum. An omentectomy is typically performed in combination with other treatments such as a hysterectomy or a salpingo-oophorectomy.
What is extraperitoneal?
Description. The extraperitoneal space is the portion of the abdomen and pelvis which does not lie withinperitoneum. It includes: Retroperitoneal space, situated posteriorly to the peritoneum. Preperitoneal space, situated anteriorly to the peritoneum.
What is extraperitoneal tissue?
In the abdomen the extraperitoneal tissue is divisible into a parietal and a visceral portion. The former lines the walls, while the latter passes between layers of the peritoneal folds to the viscera. The parietal portion is thin and comparatively free from fat over the roof and anterior wall of the abdomen.
Why are Mesenteries important?
The mesentery attaches your intestines to the wall of your abdomen. This keeps your intestines in place, preventing it from collapsing down into your pelvic area. If the mesentery doesn’t properly form during fetal development, the intestines can collapse or twist, per 2017 research.
What are Mesenteries composed of?
The mesentery is composed of two thin layers of fibrofatty tissue, which surrounds and contains the vascular and lymphatic structures supplying either the small bowel or colon. The purpose of the peritoneum and mesentery is to provide a smooth and frictionless surface between the solid organs.
What divides the Supracolic compartment?
It can be divided into a right and left subphrenic space by the falciform ligament of the liver.
How do Supracolic and Infracolic compartments communicate?
The supracolic and infracolic compartments can freely communicate by paracolic gutters. These are grooves found on the lateral side of the ascending and descending colons.
Why omentectomy is done?
An omentectomy may be recommended for an ovarian cancer patient if cancerous cells have invaded the omentum. The procedure may also be performed as a preventive measure to reduce the risk of cancer spreading from the ovaries to the stomach and other abdominal organs.
What is an Infracolic omentectomy?
Infracolic omentectomy is the removal of the greater omentum below the transverse colon. Supracolic omentectomy includes the addition of the greater omentum between the transverse colon and the stomach. Total omentectomy is the removal of the lesser omentum and supracolic omentectomy [9–11].
What is Morsion and Douglas pouch?
Morison’s pouch is an area between your liver and your right kidney. It’s also called the hepatorenal recess or right subhepatic space. Morison’s pouch is a potential space that can open up when fluid or blood enters the area.
What is the Douglas pouch?
The pouch of Douglas (cul-de-sac) represents the caudal extension of the peritoneal cavity. It is the rectovaginal pouch in the female and the rectovesical pouch in the male. The cul-de-sac is in a dependent position when either upright or supine; it is, therefore, a frequent location for seeded lesions.
What is Mesoperitoneal?
Mesoperitoneal. Retroperitoneal ( or Extraperitoneal ) Infraperitoneal / Subperitoneal. Stomach, half of the first part of the duodenum [2.2 cm], jejunum, ileum, cecum, appendix, transverse colon, sigmoid colon, rectum (upper 1/3) The rest of the duodenum, ascending colon, descending colon, rectum (middle 1/3)
Where is the extraperitoneal fascia?
Between the inner surface of the general layer of the fascia which lines the interior of the abdominal and pelvic cavities, and the peritoneum, there is a considerable amount of connective tissue, termed the extraperitoneal or subperitoneal connective tissue.
