Greater Omentum is a large fold of peritoneum (a thin layer of tissue) that hangs down from the stomach and covers the intestines. It plays a role in fat storage, immune response, and protection of abdominal organs.

Anatomy of the Greater Omentum

The greater omentum is a part of the peritoneum, specifically connected to the stomach and the transverse colon (part of the large intestine). It is like an apron that covers the intestines, providing a cushion for organs. It consists of fat, blood vessels, lymphatic tissue, and connective tissue.

• Structure: The greater omentum is a double layer of peritoneum.
• Location: It attaches to the stomach and extends down to the intestines.
• Function:
  • Fat storage: Stores fat, which can serve as an energy reserve.
  • Immune function: Contains white blood cells that help fight infections.
  • Protection: Acts as a barrier to prevent the spread of infections and trauma to internal organs.
  • Healing: Can move to damaged areas to promote healing.

Types of Greater Omentum Disorders

The greater omentum can be affected by several disorders. Here are some common types:

1. Omental Torsion: Twisting of the omentum, which can cut off blood supply and cause severe pain.
2. Omental Infarction: Death of omental tissue due to lack of blood supply.
3. Omental Cysts: Fluid-filled sacs that develop within the omentum.
4. Omental Tumors: Both benign (non-cancerous) and malignant (cancerous) tumors can occur.
5. Omental Hernia: The omentum can protrude through a weakened area in the abdominal wall.
6. Omental Abscess: Pus-filled pockets can form due to infection.
7. Peritonitis: Inflammation of the peritoneum, often involving the greater omentum.
8. Omental Adhesions: Scar tissue that causes the omentum to stick to other organs or tissues.
9. Omental Edema: Swelling of the omentum due to fluid retention.
10. Omental Involvement in Diseases: The omentum can be affected by diseases like tuberculosis or cancer.

Causes of Greater Omentum Disorders

The following are some of the potential causes of omental disorders:

1. Trauma or injury to the abdomen.
2. Infections like peritonitis.
3. Twisting or torsion of the omentum.
4. Poor blood supply leading to infarction.
5. Cancers or tumors in the omentum or nearby organs.
6. Previous abdominal surgeries that lead to adhesions.
7. Hernias that involve the omentum.
8. Systemic infections like tuberculosis.
9. Obesity, leading to excess fat in the omentum.
