Robotic repair of symptomatic Spigelian hernias: a series of three cases and surgical technique review

Spigelian hernias are a rare defect in the Spigelian aponeurosis, comprising of 0.1–2% of all hernias. These rare hernias can contain intra-abdominal tissue, and rarely bladder. Spigelian hernias pose a high risk for incarceration or strangulation of its herniated content if not repaired promptly. There are a number of routinely employed operative techniques to repair Spigelian hernias, including open or laparoscopic, suture or mesh repair, transabdominal pre-peritoneal approach or totally extraperitoneal approach. Robotic Spigelian repairs have been rarely reported in the literature. We report three cases of incarcerated Spigelian hernias that were successfully repaired robotically with mesh.
