Abdominal Hernias

See the page on Hernias for a general discussion on causes, types, treatments, etc.

External vs. Internal

  • External - Defect in the external abdominal wall that allows protrusion of abdominal contents
    • Femoral - rare; herniation along the length of the femoral artery and vein as they exit the abdominal cavity
    • Inguinal - in the groin; the region where the back leg joins the abdomen
    • Scrotal
    • Traumatic/incisional (see below)
    • Umbilical - at the site of the umbilical cord attachment
    •  other ventral mid-line hernias
  • Internal - Defect from one compartment into another without passing through the external abdominal wall; example
    • Diaphragmatic hernia - through the diaphragm and into the chest cavity or pericardial sac
      • (Basic) Diaphragmatic - herniation of abdominal contents into the chest/thorax via a defect in the diaphragm itself
      • Hiatal - hernation through/around the pre-existing hole between the chest and abdomen through which the esophagus passes before continuing into the stomach
      • Peritoneo-pericardial (through the diaphragm and extending into the pericardial sac, the sac around the heart)
