[New laparoendoscopic and minimally invasive extraperitoneal mesh augmentation techniques for ventral hernia repair]

In recent years techniques for ventral hernia repair have undergone a dynamic evolution with the development of minimally invasive and laparoendoscopic techniques. Despite the multitude of methods, five main criteria for setting the target have emerged: 1) functional and morphological reconstruction of the abdominal wall, 2) extraperitoneal mesh augmentation, 3) abandonment of penetrating fixation elements, 4) minimal surgical access trauma of the abdominal wall and 5) minimized intraperitoneal dissection that jeopardizes adherent intestinal structures. The mesh position varies between preperitoneal retromuscular and supraneurotic or preaponeurotic on the anterior rectus sheath. The different approaches can be carried out transhernially or distant from the abdominal wall defect. The latter can be realized by laparoscopic transperitoneal, endoscopic subcutaneous and endoscopic retromuscular/preperitoneal approaches. Some techniques can be extended to anterior or posterior component separation to reduce tension and to enlarge the space for mesh placement. Robot-assisted surgery opens up new perspectives in laparoendoscopic abdominal wall surgery due to additional instrumental degrees of movement. This enables the possibility of preperitoneal ventral hernia operations also behind and lateral to the posterior rectus muscle compartments as was only previously known below the arcuate line from inguinal hernia surgery.
