Epigastric Hernia — Causes, Symptoms & Surgery

An epigastric hernia occurs when fatty tissue or a part of an organ, typically a portion of the intestine, pushes through a weak spot in the abdominal wall. This type of hernia specifically develops in the epigastric region, which is the area between the belly button (navel) and the lower part of the breastbone (sternum). While often small and sometimes asymptomatic, epigastric hernias can cause discomfort and pain, particularly when straining or engaging in physical activity. Understanding the causes, recognising the symptoms, and knowing the available surgical options are crucial for effective management and treatment.

What Causes an Epigastric Hernia?

Epigastric hernias develop due to a weakness or defect in the linea alba, a fibrous band of tissue that runs down the midline of the abdomen, where the abdominal muscles meet. This weakness can be present from birth (congenital) or develop over time (acquired). Several factors can contribute to the formation or worsening of an epigastric hernia:

• Congenital Defects: Some individuals are born with a naturally weaker linea alba.
• Obesity: Excess weight puts additional strain on the abdominal muscles.
• Pregnancy: The growing uterus and hormonal changes can weaken abdominal tissues.
• Chronic Coughing: Persistent coughing can exert considerable pressure.
• Heavy Lifting: Improper lifting techniques or regularly lifting heavy objects.
• Straining: Chronic constipation or urinary issues can increase intra-abdominal pressure.
• Previous Abdominal Surgery: Incisions from prior surgeries can create weak points.

Recognising the Symptoms of an Epigastric Hernia

The symptoms of an epigastric hernia can vary widely. Some people may have no noticeable symptoms, while others experience significant discomfort. The most common signs and symptoms include:

• A Visible Bulge: A small lump or swelling in the epigastric region, between the navel and the sternum.
• Pain or Discomfort: Pain is often experienced at the site of the bulge, worsening with activities like bending or lifting.
• Tenderness: The area around the hernia may be tender to the touch.
• Digestive Issues: Nausea, vomiting, or constipation if a portion of the intestine is involved.
• Redness or Discoloration: In severe cases, the skin over the bulge may appear red or discoloured, indicating a medical emergency.

It is important to note that the size of the hernia does not always correlate with the severity of symptoms. A small hernia can sometimes cause more pain than a larger one.

Diagnosis and Treatment Options for Epigastric Hernia

Diagnosing an epigastric hernia typically involves a physical examination by a doctor. Imaging tests, such as an ultrasound or CT scan, may be used to confirm the diagnosis, assess the size of the hernia, and rule out other conditions.

The only definitive treatment for an epigastric hernia is surgical repair. While small, asymptomatic hernias may be monitored, most doctors recommend surgery to prevent potential complications, such as incarceration or strangulation, which can be life-threatening. Surgical options include:

• Open Hernia Repair (Herniorrhaphy): This traditional method involves making an incision over the hernia site. The protruding tissue is gently pushed back, and the weakened abdominal wall is repaired with sutures, often reinforced with a synthetic mesh.
• Laparoscopic Hernia Repair: This minimally invasive approach involves several small incisions. A laparoscope and surgical instruments are inserted to repair the hernia from within the abdomen, often using a mesh. This method typically results in less pain and a faster recovery time.
