[Spigelio's hernia. Anatomo-clinical considerations and description of 5 clinical cases].
Spigelian hernia, or ventro-lateral hernia is a rare clinical condition, it represents about 1.5% of hernial formation cases of the abdominal wall. It is localised laterally to the rectus muscle and emerges from the semilunar arch. The line, which joins the IX rib to the pubic tubercle, defines the limit between muscular and aponeurotic portion of trasversus abdominis muscle. Diagnosis often results misunderstood. As a matter of fact, this hernia has typically an intraparietal localization and the clinical picture seldom presents characteristic signs. The hernial sac and its content can be appreciated subcutaneously in only 2% of cases. It is estimated that about 50% of patients affected by this condition have a certain diagnosis before surgery. The early clinical signs are generally aspecific and deceitful, represented by oppressive grief and rarely by an abdominal wall tumor; it occurs that it starts with a complication: intestinal occlusion (23%), subocclusion (8%), strangulation (20%, but some authors report percentage up to 50%). We report 5 cases who came to our observation during the last 7 years; all patients underwent elective surgery, and specifically 3 patients in day surgery. Starting from the discussion of these cases, we review anatomy, etiology, clinical nature, instrumental investigation and surgical technique of this rare kind of hernia, comparing our experience to literature reported case histories.
