The predominant factor in successful preperitoneal hernia repair is adequate dissection with complete exposure and coverage of all potential groin hernia sites. Hematoma mesh lifting and inadequate lateral inferior and medial inferior mesh fixation represent the most common causes of recurrence for surgeons experienced in traditional or laparoscopic preperitoneal hernia repair.

Traumatic lumbar hernias are associated with a high incidence of intra-abdominal injury and should be considered in all cases of severe blunt abdominal trauma. Computed tomography should be implemented when the diagnosis is suspected in a hemodynamically stable patient. Repair should be performed by mesh patching techniques at a time based on clinical correlation.
