Hernia by definition is protrusion of tissue from inside the abdominal cavity through a defect in the abdominal wall. Hernias are classified based on the location and size.

In the abdomen, the most common areas are: 
1) Groin (Inguinal and Femoral)
2) Umbilical 
3) Incisional (site of previous surgery) 
4) Epigastric 
5) Hiatal (junction of esophagus and stomach) 
6) Lumbar (between back muscles)

The risk factors for inguinal hernia (IH) include: family history, previous contra-lateral hernia, male gender, age, abnormal collagen metabolism, prostatectomy, and low body mass index. Peri-operative risk factors for recurrence include poor surgical techniques, low surgical volumes, surgical inexperience and local anesthesia
