[Spieghel hernia--a rare cause of acute abdomen].

Spieghelian hernia is a rare rupture of the abdominal wall along the linea semilunaris. Due to the fact that the rupture is overlain by the aponeurosis of M. externus abdominis, it is often not recognized in its early stage. In most cases the rupture neck is mostly very narrow and in 24.1% of all cases an incarceration of intestinal parts has ensued which may even lead to the development of an acute abdomen. The first choice therapy will consist in an operative support including the reposition of the hernial content and a possible resection of ischaemic organs as well as removal and sealing of the hernia. Because of the rarity of this sickness we report on a patient in our clinic who was operated as an emergency.
