Strangulation of an inguinal hernia most commonly occurs at the external inguinal ring:

  • constriction of the hernial neck, or twisting of the hernia, initially obstructs venous return
  • oedema eventually obstructs arterial supply
  • eventually the bowel necroses and perforates into the hernial sac

Inguinal hernial stragulation occurs most commonly in two age groups:

  • most commonly in the elderly
  • infants in the first 6 months of life, when up to 25% of inguinal herniae obstruct if untreated
