Ambulatory laparoscopic repair of inferior lumbar or Petit hernia: a case report.

Lumbar hernias are an uncommon variety of abdominal wall defect. Diagnosis depends largely on the capacity for clinical suspicion, and confirmation is based on imaging tests. Surgical treatment is controversial due to difficulty in defining the borders of the lumbar defect and the involvement of a bone margin. We present a case of traumatic lumbar hernia in the Petit triangle, diagnosed by computed tomography (CT) and repaired laparoscopically as a major ambulatory surgery procedure. The laparoscopic approach enabled us to identify the whole of the lumbar area and effect a profound reconstruction on the same side as the defect.
