Non-midline abdominal wall hernias present unique anatomic challenges, making repair more complex. The constraints of the peritoneal cavity, pelvis, and costal margin limit the utility of intraperitoneal mesh repair, and extra-peritoneal repairs have traditionally been performed using open techniques, often resulting in higher wound morbidity. Advances in minimally invasive surgery make visualization and dissection of such complex cases feasible, with all the attendant benefits of a minimally invasive over an open approach. In this study, we examined the use of the robotic platform to repair non-midline hernias. Retrospective review of all non-midline abdominal wall hernias was performed robotically at Prisma Health, excluding parastomal hernias. Study conducted and outcomes reported according to STROBE statement. Repair was performed in the retro-rectus (n = 3) or retro-rectus + transversus abdominis release (TAR) (n = 39), pre-peritoneal (n = 22), and intraperitoneal (n = 1). Mean hernia width was 9.4 cm, permanent synthetic mesh used for all repairs. Mean LOS was 1.5 days. Surgical-site occurrence (SSO) occurred in 49.2%, 78% of which were simple seroma. Three patients (4.6%) developed surgical-site infection (SSI). Two recurrences were identified with a mean follow-up of 11 mos. The robotic platform facilitates complex dissection to allow minimally invasive, extra-peritoneal repair of complex non-midline hernias. This approach overcomes the anatomic constraints of intraperitoneal mesh repair and the wound morbidity of open repair.
