[Spiegel's hernia: apropos of 7 cases].

The authors present their experience with Spiegel's hernia and a series of seven cases, three of which debuted as intestinal occlusion. On four occasions the hernial content was appreciated, only one of which required resection. The diagnostic procedures most commonly used in this pathology are noted and it is concluded that sonography offers high resolution images and effectiveness in the differential diagnosis. In all the cases the hernia was located below the aponeurosis of the major oblique muscle. Herniorrhaphy was performed in every case, and there was no morbidity, mortality or recurrence of the hernia.
