Mesothelioma Peritoneum

The Mesothelioma – Peritoneum

The peritoneum is the mesothelium membrane surrounding the abdominal cavity as well as many of the abdominal organs. The peritoneal mesothelium is a protective, double layered membrane. The first layer of the peritoneum immediately surrounds the abdominal cavity. The second layer forms a sac around the first layer, with fluid lubricating the area between the layers. This lubricant allows the organs of the abdomen to glide easily around surrounding tissue, and it protects the abdomen from damage. Peritoneal mesothelioma attacks the peritoneum....>>> Type of Lung Cancer. Pleural Mesothelioma | Pericardial Mesothelioma | Peritoneal Mesothelioma.<<<

Mesothelioma Type of Lung Cancer

Although ultimately two types of peritoneum is referenced:

• Parietal peritoneum is that portion that lines the abdominal and pelvic cavities. Those cavities are also known as the peritoneal cavity.
• Visceral peritoneum covers the external surfaces of most abdominal organs, including the intestinal tract.

As the intestines are, in essence, suspended from the dorsal aspect of the peritoneal cavity by a fused, double layer of parietal peritoneum called mesentery. In come cases, parietal and visceral peritoneum is also continuous along the ventral abdomen, where they are called ventral mesentery.

Some organs protrude into the abdominal cavity, but are not encased in visceral peritoneum. The kidneys lay in this type of position and are said to in a retroperitoneal location.

Pleural Mesothelioma Peritoneal

The term mesentery tends to be used as a generic term describing peritoneal extensions not only from the intestine, but from all abdominal and pelvic organs. To be more precise, and less offensive to language purists, sections of peritoneum that suspend specific organs are individually named, for example, mesogastrium for the stomach, mesojejunum for the jejunum and mesometrium for the uterus.

An important feature of mesentery is that it serves as a conduit for blood vessels, nerves and lymphatic vessels going to and from the organ in question. The image below shows a loop of small intestine from a mouse. The glistening membrane inside the loop of bowel is mesentery; mesenteric blood vessels running through bundles of fat are clearly visible.

Omentum: Omenta are abdominal structures formed from peritoneum and structurally similar to 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. The lesser omentum arises from the lesser curvature of the stomach and extends to the liver. The greater omentum is given off from the greater curvature of the stomach, forms a large sheet that lies over the intestines, and then converges into parietal peritoneum.

Pericardial Mesothelioma Pericardial

Mesothelioma cancer affects the serous membranes that surround the major organs in the midsection of the body. Different organs can be affected by mesothelioma because the serous membranes surround the lungs, heart, abdomen and others. The most common type of mesothelioma is that which affects the lung lining, and is called pleural mesothelioma. Other types are pericardial mesothelioma, which affects the lining of the heart, and peritoneal mesothelioma, affecting the lining of the abdomen.

Diagnosis: When considering a diagnosis of asbestosis, your doctor will probably inquire as to your exposure to asbestos. He-she may also ask whether any fellow employees have been affected by the disease....Mesothelioma Diagnosis

Treatment: The affects of asbestosis cannot be reversed but progression can be halted and symptoms treated. Above all us, further exposure to the toxic material should be eliminated. If you smoke, it’s necessary to stop immediately.....Mesothelioma Treatment
