[Spigelio's hernia: presentation of 2 clinical cases and review of the literature].

The authors present two cases of Spigelian hernia. The patients underwent surgery, in one case with urgency modality. They repaired surgically both hernias, by a plastic of the abdominal wall. Neither postoperative mortality, nor morbidity have been observed. On follow-up, they didn't observe any relapse. Nevertheless the extreme rarity of the Spigelian hernia, the authors believe that this pathology must be considered among the different causes of the partial intestinal obstruction or acute abdomen. The diagnosis can be performed both by the simple clinical examination and by instrumental devices. Ultrasonography seems to be the most specific and the less invasive one. Recently laparoscopic approach has been emphasized; it allows to reach the diagnosis and to treat the hernia at the same time. However the authors remark that traditional surgery remains the most effective treatment.
