[Lumbar hernias in adults. Apropos of 4 cases and review of the literature].
Lumbar hernias are rare (2% of abdominal wall hernias). Symptomatology consists frequently only of an arch formation seen best with the patient sitting and when coughing. In adults it is twice as frequent in women and on the left side. Acute events, dominated by incarceration of a digestive segment, particularly colic, often suggest the diagnosis (10% of cases). Diagnosis is simple when confronted with a large hernia, but difficulties arise with those less than 5 cm in diameter, often diagnosed as a lipoma or parietal tumor. Conventional radiographs and ultrasound images are usually sufficient to establish the correct diagnosis and to determine the content of the hernial sac, but computed tomography scans can provide data on the exact limits of the defect and allow evaluation of possible problems during surgical repair. Rarely congenital (10%), these hernias occur either secondary to a violent lumbo-abdomino-pelvic injury (25%) or following surgical intervention to the lumbar region (50% of cases). Small hernias can be repaired using the direct approach but larger deficits require the insertion of a reinforcing non absorbable prosthesis. Long term results, both for the 4 cases reported and those published in the literature, were assessed as satisfactory.
