A spigelian hernia is a protrusion through an anterior abdominal wall defect along the linea semilunaris. The traditional method of repair consists of an open surgical technique requiring a lengthy abdominal incision to allow visualization of the defect. However, with the emergence and availability of laparoscopic techniques, a minimally invasive approach is feasible. Only eight prior case reports have documented emergent laparoscopic repair of a spigelian hernia. We describe the first successful laparoscopic repair of a spigelian hernia in an emergent setting at our institution.
