- 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.
- Small bowel obstruction
- Incarceration: hernia cannot be reduced or pushed back manually
- Strangulation: ischemia caused by a compromised blood supply
