Hernia imaging

How surgeons use exam findings and imaging to confirm a hernia, characterize its anatomy, and plan repair.

Most hernias are diagnosed on physical examination. Imaging is added selectively — to characterize complex hernias, find occult hernias, plan operations, or evaluate complications.

Physical examination

When used: First-line for most hernias.

Advantages

  • No radiation, no cost
  • Often diagnostic on its own
  • Allows reducibility assessment

Limitations

  • Operator-dependent
  • Limited for occult or small defects

Ultrasound

When used: Useful when the exam is inconclusive or for occult groin hernias.

Advantages

  • No radiation
  • Dynamic — can image with Valsalva
  • Widely available

Limitations

  • Operator-dependent
  • Less detail for complex ventral hernias

CT scan

When used: Standard for complex, recurrent, and ventral hernias.

Advantages

  • Excellent anatomic detail
  • Defect size, contents, and surrounding structures
  • Surgical planning gold standard for complex repairs

Limitations

  • Radiation exposure
  • Cost

MRI

When used: Selected cases — chronic groin pain, occult sports hernia, mesh complications.

Advantages

  • No radiation
  • Excellent soft-tissue detail

Limitations

  • Cost and availability
  • Longer scan time

Endoscopy

When used: Used for hiatal hernias and to evaluate reflux complications.

Advantages

  • Direct mucosal visualization
  • Allows biopsy

Limitations

  • Invasive
  • Requires sedation
