What is a Spigelian hernia?
A Spigelian hernia occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal wall, specifically along the Spigelian fascia. This type of hernia is relatively rare and typically presents as a bulge or lump along the lower edge of the abdomen, near the waistline.
What causes Spigelian hernias?
Several factors can contribute to the development of Spigelian hernias, including:
- Weakness or defect in the Spigelian fascia
- Activities or conditions that increase pressure in the abdomen, such as obesity, heavy lifting, or chronic coughing
- More common in adults, particularly females
What are symptoms of a Spigelian hernia?
- Visible bulge or lump along the side of the abdomen, often near the waistline or below the belly button is the most common symptom of a Spigelian hernia.
- Discomfort, tenderness, or aching around the bulge, particularly when touching it or engaging in activities such as bending over or lifting heavy objects.
- Nausea, vomiting, or constipation, especially if the protruding tissue becomes trapped or twisted (incarcerated or strangulated hernia).
What are treatment options for a Spigelian hernia?
For small, asymptomatic Spigelian hernias, your doctor may recommend monitoring the hernia regularly for any changes.
Wearing a supportive device such as a hernia belt or binder may help manage symptoms and provide temporary relief.
Surgery is often recommended for symptomatic or enlarging Spigelian hernias. During surgery, the protruding tissue is repositioned, and the weakened abdominal wall is reinforced with stitches or a synthetic mesh.
