Obstructed Hernia

Overview

An obstructed or strangulated hernia is a surgical emergency. Without prompt treatment, the trapped bowel can be damaged.

Symptoms

• A hernia lump that becomes painful, firm or cannot be pushed back
• Severe abdominal pain
• Nausea and vomiting
• Not passing stool or wind
• Redness over the lump and fever

Causes and risk factors

Any hernia can become obstructed, including inguinal, femoral, umbilical and incisional hernias. Femoral hernias carry a higher risk.

Diagnosis

A surgeon examines the hernia. Ultrasound or CT may be used.

Treatment

Treatment is urgent surgery to release the trapped bowel and repair the hernia. Damaged bowel may need to be removed.

When to see a doctor

Seek emergency care if a hernia becomes painful, hard or cannot be pushed back. Having a known hernia repaired early reduces this risk.
