Robotic Versus Open Comparison in the Surgical Treatment of Wide Abdominal Wall heRnias (ROCSTAR)

In the treatment of ventral incisional hernias, a mesh repair in the retromuscular plane is considered as the gold standard. To allow for adequate medialization of the fascial borders and a complete closure of the defect in case of large incisional hernias, component separation techniques are increasingly being used. When compared to anterior component separation, posterior component separation by transversus abdominis release (TAR) seems to decrease postoperative wound problems. While laparoscopic techniques pose significant difficulties to perform TAR minimally invasively (mainly due to ergonomic and technical reasons), these limitations seem to be overcome by robotic platforms. Initial retrospective patient series report on significantly shorter postoperative hospital stay and fewer complications after robotic transversus abdominis release (rTAR), when compared to open transversus abdominis release (oTAR). High-quality prospective evidence on rTAR is currently lacking.
