Complex ventral hernia repair is an involved area in abdominal wall surgery especially among patients who have big defects, recurrent hernias or a big abdominal wall weakness. Conventional open repair surgery is considered to cause increased morbidity after surgery, and delayed recovery. Robotic surgery has recently become one of the latest forms of minimally invasive surgery that allows a surgeon to carry out a complex abdominal wall reconstruction with better visualization, known to be more dexterous in provision and better ergonomic than traditional laparoscopy. Two of the robotic methods that are today applied to the repair of ventral hernia, the robotic extended totally extraperitoneal repair (eTEP) and robotic transversus abdominis release (rTAR) have become increasingly popular. The two methods support the insertion of retromuscular mesh and seek to provide lasting repair of hernias with minimum intraperitoneal complications. The purpose of this systematic review and meta-analysis is to find the differences in perioperative and postoperative outcomes of robotic eTEP and robotic TAR in treating complex ventral hernia. To locate the studies providing the outcomes of robotic abdominal wall reconstruction methods, the thorough literature search in the large electronic databases such as PubMed, Scopus, Web of Science, and Embase was carried out. They included studies of adult patients that undergo ventral hernia repair through robotic eTEP or robotic TAR. Her mother had hernia recurrence and general postoperative complications as the primary outcomes and operation time, length of hospital stay, seroma formation and surgical site infection as the secondary outcomes. The combined evidence indicates that robotic eTEP and robotic TAR are safe and effective methods of a complex ventral hernia repair. Robotic eTEP was mostly linked with shorter operative time and less hospital stay whereas robotic TAR was more likely to be used to treat a large or complex defect because it could provide more fascial medialization. Complications and second time outcomes were similar in regards to overall complications and recurrence. Finally, robotic eTEP and robotic TAR are capable of being effective minimally invasive interventions in the repair of complex ventral hernias. The technique is to be selected personally depending on the nature of the hernia, patient and the experience of the surgeon. Additional superior comparative research works will be necessary to develop the best surgical management techniques.
