Definitions

An abdominal hernia is a protrusion of an internal organ, fat, or tissue through an abnormal opening or weak spot in the muscle and connective tissue (fascia) of the abdominal wall.

Common types of abdominal hernias include:

• Inguinal hernia: account for 70% to 75% of all abdominal wall hernias; occurs in the groin area and is much more common in men.
• Umbilical hernia: located at or within 3 cm of the navel; accounts for 6% to 14% of adult abdominal wall hernias.
• Incisional / Ventral hernia: develops at the site of a previous surgical scar due to incomplete healing or weakness.
• Femoral hernia: occurs just below the inguinal ligament in the femoral canal; carries a high risk of becoming strangulated
