Answer

If an incarcerated or strangulated hernia is suspected, the following imaging studies may be helpful:

  • Upright chest radiograph to exclude free air (extremely rare)
  • Flat and upright abdominal films to diagnose a small bowel obstruction (neither sensitive or specific) or to identify areas of bowel outside the abdominal cavity
