types of abdominal wall hernias
Inguinal Hernias.âInguinal hernias are the. most common type of abdominal wall hernia. They may occur in children (most commonly in-. direct type hernias) or adults (both direct and. indirect types), manifesting medial (direct type) or lateral (indirect type) to the inferior epigastric. vessels (Fig 2).
Ventral hernias include all hernias in the anterior and lateral abdominal wall. Midline defects include umbilical, paraumbilical, epigastric, and hypogastric hernias. Umbilical hernias are by far the most common type of ventral hernia; they are usually small and are particularly common in women.
Interparietal (interstitial) hernia refers to a hernia sac located in the fascial planes between the abdominal wall muscles that does not exit into the subcutaneous tissue. This type of hernia occurs most frequently in the inguinal region.
