[edit] Discussion

  • Inguinal hernias are the most common type of abdominal wall hernia.
  • 2 types
    • Medial to inferior epigastric vessels (direct type)
    • Lateral to inferior epigastric vessels (indirect type).
  • More common in males than in females.
  • In boys, most inguinal hernias develop because the peritoneal extension accompanying the testis fails to obliterate.
  • In adults, inguinal hernias are caused by acquired weakness and dilatation of the internal inguinal ring.
  • Complications
    • Small bowel obstruction
    • Incarceration: hernia cannot be reduced or pushed back manually
    • Strangulation: ischemia caused by a compromised blood supply
