An omentocele is a herniation of the omentum—a fatty layer of tissue in the abdomen—through a weakness or defect in the abdominal wall.
In simpler terms: It means that a portion of the omentum is protruding out of its normal place inside the abdomen, usually through a hole or weak spot.
Understanding Omentocele
-
Omentum: The omentum is a large apron-like fold of visceral peritoneum that hangs down from the stomach. It contains fat and helps to cushion abdominal organs, isolate infections, and support the immune system.
-
Herniation: Herniation refers to the abnormal protrusion of an organ or tissue through a defect in the wall of the cavity that normally contains it.
Causes of Omentocele
Omentoceles can be caused by:
- Weakness in the abdominal wall: This can be due to previous surgery, injury, or congenital defects.
- Increased pressure within the abdomen: This can be caused by things like chronic coughing, straining during bowel movements, or pregnancy.
- Obesity: Excess weight can strain the abdominal wall.
Symptoms of Omentocele
Symptoms may include:
- A visible bulge under the skin.
- Pain or discomfort in the area of the bulge, especially with activity or straining.
- Sometimes, there are no symptoms at all.
Diagnosis and Treatment
An omentocele is usually diagnosed through a physical examination. Imaging tests, such as an ultrasound or CT scan, may be used to confirm the diagnosis. Treatment usually involves surgery to repair the defect in the abdominal wall and return the omentum to its proper position.
