Lumbar hernias are a rare form of abdomen wall hernias. As this is a rare disease, treatment options are not standardized. Most case reports, even recent ones, describe open techniques. A minimally invasive method, though feasible, is not done by most surgeons. Among the minimally invasive techniques, the transabdominal method is commonly performed. A totally extraperitoneal (TEP) approach is a good alternative, which can be done with minimal complications. Here, we describe a case report of a patient who had a superior lumbar hernia (Grynfeltt's) and inguinal hernia, who successfully underwent simultaneous TEP repair for the lumbar and inguinal hernia.
