In indirect inguinal hernia, the contents herniate into the inguinal canal through the deep inguinal ring. The hernial sac lies within the spermatic cord. | In indirect inguinal hernia, the contents herniate into the inguinal canal through the deep inguinal ring. The hernial sac lies within the spermatic cord. It develops due to incomplete obliteration of processus vaginalis during foetal development. | ||
In direct inguinal hernia, the contents herniate directly through the posterior wall of the inguinal canal. The hernial sac lies outside the spermatic cord. | In direct inguinal hernia, the contents herniate directly through the posterior wall of the inguinal canal. The hernial sac lies outside the spermatic cord. It develops due to herniation through a weakened posterior wall of the inguinal canal, usually due to a disease which increases intraabdominal pressure like [[COPD]] and [[constipation]]. It may also occur during exercise. | ||
During surgery, the two types of inguinal hernia can be differentiated by observing the hernia’s relation to the inferior epigastric vessels. Indirect hernia lies laterally to the vessel, while direct hernia lies medially. | During surgery, the two types of inguinal hernia can be differentiated by observing the hernia’s relation to the inferior epigastric vessels.

Recurrence is more common with tension repair, and so tension-free repair is preferred with mesh is usually preferred. If the risk of infection is high (nearby infection, bowel injury), the hernia is very small, or the patient is very young, mesh repair is not preferred. | Recurrence is more common with tension repair, and so tension-free repair is preferred with mesh is usually preferred.
