Answer

As much as 10% of the population develops some type of hernia during life. [19] More than 1 million abdominal hernia repairs are performed each year, with inguinal hernia repairs constituting nearly 770,000 of these cases. [1, 2, 3] Frequencies of various types of hernias are as follows:

  • Approximately 75% of all hernias are inguinal; of these, 50% are indirect (male-to-female ratio, 7:1), with a right-side predominance, and 25% are direct [5] ; 3% of inguinal hernias have a sliding component, most often on the left side (left-to-right ratio, 4.5:1)
  • About 14% of hernias are umbilical
  • About 10% of hernias are incisional or ventral (female-to-male ratio, 2:1) [7]
  • Only 3-5% of hernias are femoral
  • Interparietal, supravesical, lumbar, sciatic, and perineal hernias are rare; interparietal hernias are on the right side in 70% of cases, and a similar percentage of cases involve testicular maldescent (Denis-Browne pouch)
