Topic: Visceral peritoneum


In the News (Tue 14 Feb 12)

  
  Peritoneum
The peritoneum is thin membrane that lines the abdominal and pelvic cavities, and covers most abdominal viscera.
In come cases, parietal and visceral peritoneum are also continuous along the ventral abdomen, where they are called ventral mesentery.
The visceral peritoneum covering the stomach extends on both sides into large, double-layered sheets that are filled with prominent patches of fat, giving it a lace-like appearance.

PERITONEUM [peritoneum], multilayered membrane which lines the abdominal cavity, and supports and covers the organs within it.
The portion that covers the internal organs, or viscera, is known as the visceral peritoneum and forms the outer layer (serosa) of most of the intestinal tract.
The space between the visceral and parietal membranes contains a watery fluid that permits the abdominal organs to slide freely against the abdominal wall.

 Chapter 26: The abdominal viscera and peritoneum
The peritoneum is a smooth, glistening, serous membrane that lines the abdominal wall as the parietal peritoneum and is reflected from the body wall to various organs, where, as visceral peritoneum, it forms an integral part as the outermost, or serosal, layer.
The pericardium, pleura, and peritoneum have a similar arrangement in the parietal and visceral layers, with a cavity between.
The extraperitoneal tissue external to the parietal peritoneum is carried with the reflections to the organs and becomes a part of the serosal layer.

 Med-Lib - Medical Online Library - English Articles - Oxford Textbook of Surgery - The peritoneum and peritonitis
The pattern of innervation of the visceral and parietal peritoneum determines the pattern of abdominal pain that occurs when the peritoneum is inflamed.
As the visceral peritoneum receives only afferent innervation from the autonomic nervous system, stimuli from the visceral peritoneum are localized only to the foregut, midgut, or hindgut in the midline.
In summary, the signs and symptoms of peritonitis secondary to a diseased abdominal viscus are as follows: initial inflammation of the visceral peritoneum overlying the damaged organ results in poorly localized abdominal pain, through stimulation of the visceral autonomic nerves.

 Peritoneum - Wikinfo
The peritoneum consists of two layers: the outer layer, called the parietal peritoneum, is attached to the abdominal wall and the inner layer, the visceral peritoneum, is wrapped around the internal organs that are located inside the abdominal cavity.
The peritoneum both supports the abdominal organs and serves as a conduit for their blood and lymph vessels and nerves.
Two notable sections of the peritoneum in humans are the omenta, the greater (gastrocolic) omentum and the lesser (gastrohepatic) omentum.

 Peritoneal Surface Malignancy - Principles of Management
With traction on the spleen, the peritoneum anterior to the pancreas is stripped from the gland using electrosurgery.
This allows strong traction to be exerted on the tumor specimen throughout the left upper quadrant and separation of surface tumor from all normal tissue in the left upper quadrant to the diaphragmatic muscle, the left adrenal gland, and the superior half of perirenal fat.
The tumor-bearing peritoneum is stripped from the posterior surface of the lower abdominal incision, exposing the rectus muscle.

 Peritoneum Summary
The inner layer, the visceral peritoneum, is wrapped around the internal organs that are located inside the abdominal cavity.
The mesentery is the part of the peritoneum through which most abdominal organs are attached to the abdominal wall and supplied with blood and lymph vessels and nerves.
The structures in the abdomen are classified as intraperitoneal, retroperitoneal or infraperitoneal depending on whether they are covered with visceral peritoneum and have a mesentery or not.

 Anatomy
An omentum is a double-layered extension of visceral peritoneum that passes from the stomach and the proximal part of the duodenum to another organ or structure.
The lesser omentum is a double layer of peritoneum that connects the lesser curvature of the stomach and proximal part of the duodenum to the liver around the margin of the porta hepatis.
The posterior surface is covered by visceral peritoneum, and its anterior surface adheres to the liver.

The vesical peritoneum anteriorly is hardly noticeable unless the bladder is filled, and when it is, it remains an extra-peritoneal organ covered by parietal peritoneum.
Posteriorly, these organs and their ligamentous structures continue to be covered by visceral peritoneum as it drapes abruptly medially and continues downward to the uterine cervix.
The 'broad ligament', actually a mesentery adjacent to the uterus laterally on either side, is comprised of anterior and posterior parietal peritoneum, with vessels between.

 Mesentery - Wikipedia, the free encyclopedia
Mesentery is an anatomical term that specifically refers to the double layer of peritoneum that connects a part of the small intestine to the posterior wall of the abdomen.
The peritoneum that lies on the walls of the abdominopelvic cavity (parietal peritoneum) invaginates at certain parts, with an organ inside this invagination.

 Peritoneal Treatments
A cancer affecting the abdominal lining, or peritoneum (paira-tin-e-um) is therefore a very serious and hard to treat matter.
The visceral peritoneum covers the internal organs and makes up most of the outer layer of the intestinal tract while the parietal peritoneum covers the abdominal cavity.
The peritoneum is located in an area of soft tissues, easily accessed and pliable, where the pleura is found inside a rigid space (the rib cage) and is difficult to reach without cutting through bone.

Serosa is the outermost layer of the tract.
The parietal peritoneum lines the inside of the abdominal cavity while the visceral peritoneum covers the organs inside the abdominal cavity.
Organs that lie in the posterior part of the abdominal cavity are described as retroperitoneal, examples, are the pancreas, kidneys and some part of the large intestine.

 Alternative techniques and materials for caesarean section
As some indirect evidence suggests that leaving the peritoneum unsutured could be beneficial, a policy of non-closure of the peritoneum could be considered.
However, the results must be interpreted with caution as there was clinical heterogeneity among the trials, with incidences ranging from 0% to 23% in the experimental arm and from 0% to 30% in the control group.
When both visceral and parietal peritoneums were not sutured the result was shorter stay in hospital (six trials, 974 women).

 Peritoneum - Wikipedia, the free encyclopedia
Although they ultimately form one continuous sheet, two types or layers of peritoneum are referenced to and a potential space between them:
As the mesoderm differentiates, one region known as the lateral plate mesoderm splits to form two layers separated by an intraembryonic coelom.
Some structures, such as the kidneys, are "primarily retroperitoneal", meaning that structure developed intraperitoneally but lost its mesentery and thus became retroperitoneal.

Now examine the peritoneum which lines the abdominal cavity.
It is divided into two parts: the visceral peritoneum, which covers the surface of the visceral organs, and the parietal peritoneum, which lines the internal surface of the walls of the abdominal and pelvic cavity.
Inside the abdominal cavity the peritoneum forms folds or reflections, referred to as mesenteries and peritoneal ligaments.
