Enlarged spleen. If the cause of the enlarged spleen can't be determined or if the condition is causing serious complications such as a ruptured spleen, doctors may suggest removing the spleen.

Cancers that originate in the spleen are relatively rare. When they do occur, they are almost always lymphomas, blood cancers that occur in the lymphatic system.

Usually lymphomas start in other areas and invade the spleen. According to the National Cancer Institute , adult non-Hodgkin lymphoma can have a spleen stage.

This type of spleen invasion can also happen with leukemia, blood cancer that originates in bone marrow. Rarely, other types of cancers — like lung or stomach cancers — will invade the spleen.

Spleen cancer symptoms may resemble a cold or there may be pain or fullness in the upper abdomen. Gut bacteria and vitamin D: What is the link?

Polysplenia syndrome. Splenic implant assessment in trauma. Chirurgia Bucur. Inside, the mass of splenic tissue is of two types, the red pulp and the white pulp, which do not separate into regions but intermingle and are distributed throughout the spleen.

The white pulp is lymphoid tissue that usually surrounds splenic blood vessels. The red pulp is a network of splenic cords cords of Billroth and sinusoids wide vessels filled with blood, and it is in the red pulp that most of the filtration occurs.

The white pulp of the spleen contains typical lymphoid elements, such as plasma cells, lymphocytes , and lymphatic nodules, called follicles in the spleen.

Germinal centres in the white pulp serve as the sites of lymphocyte production. Similar to the lymph nodes, the spleen reacts to microorganisms and other antigens that reach the bloodstream by releasing special phagocytic cells known as macrophages.

Splenic macrophages reside in both red and white pulp, and they serve to remove foreign material from the blood and to initiate an immune reaction that results in the production of antibodies.

Most operations to remove spleens are carried out using keyhole surgery laparoscopy. Keyhole spleen removal allows a surgeon to get inside your tummy abdomen to your spleen without having to make large cuts.

This means you'll have less scarring and may recover from the operation more quickly. But you'll still need a general anaesthetic.

Open surgery is where one large cut is made. It may be needed if your spleen is too large or too damaged to be removed using keyhole surgery.

Often, in emergencies, this is the preferred method. You'll need a general anaesthetic and may need to stay in hospital for a few days to recover. It's normal to feel sore and be bruised after a splenectomy, but you'll be given pain relief.

Like any operation, spleen removal carries a small risk of complications, including bleeding and infection.

The spleen is a soft organ with a thin outer covering of tough connective tissue, called a capsule. There is a handy rule to remember the rough dimensions of the spleen, called the 1x3x5x7x9x The spleen sits in the upper left part of your abdomen. It’s located behind your ribs, under your diaphragm, and above and behind to your stomach. This fist-shaped, oblong organ is purple, and it. Your spleen is an organ located just below your left rib cage. Many conditions — including infections, liver disease and some cancers — can cause an enlarged spleen, also known as splenomegaly (spleh-no-MEG-uh-lee). An enlarged spleen usually doesn't cause symptoms. It's often discovered during a routine physical exam. The spleen is an organ in the upper far left part of the abdomen, to the left of the stomach. The spleen varies in size and shape between people, but it’s commonly fist-shaped, purple, and about 4. The spleen is part of your lymphatic system, which fights infection and keeps your body fluids in balance. It contains white blood cells that fight germs. Your spleen also helps control the amount of blood in your body, and destroys old and damaged cells. Certain diseases might cause your spleen to swell.
