P135 ESTABLISHMENT OF MINIMALLY INVASIVE VENTRAL HERNIA REPAIR WITH EXTRAPERITONEAL MESH PLACEMENT AS A STANDARD APPROACH OF VENTRAL HERNIA REPAIR USING THE ROBOTIC PLATFORM

Aim Several meta-analyses indicated, that extraperitoneal mesh placement in the retromuscular or preperitoneal space shows advantages over intraperitoneal mesh placement. Previous surgical interventions which included extraperitoneal mesh placement were usually performed using open surgery. For several years now, our hospital has pursued to treat ventral hernias using a minimally invasive approach with extraperitoneal mesh placement. A Da Vinci X system has been available since the beginning of 2019. The aim of this analysis is to show the process of changing the operative procedure in ventral hernia repair over the period from 2016 to 2020. Material and Methods All hernia operations from 2016-2020 were evaluated using our hospitals information system. Every surgical intervention which included ventral hernia repair with the indication for mesh implantation was taken into the analysis. Results In 2016, the proportion of minimally invasive procedures was 36.67%. In all of these cases an intraperitoneal mesh was implanted in the abdominal cavity (laparoscopic IPOM operation). Open surgery was performed in 63.33%, out of which we implanted an intraperitoneal mesh in 23.68%, a retromuscular mesh in 73.68% and an onlay mesh in 2.63% of the cases. In 2020, the proportion of minimally invasive operations was already 87.5%, of which 83.33% were performed robotically assisted and 16.67% laparoscopically. In 94.29% of the minimally invasive operated patients an extraperitoneal mesh implantation was carried out, among which 75.76% were placed in the retromuscular and 24.24% in the preperitoneal position. Conclusions The majority of elective operations on ventral hernias can be performed in a minimally invasive technique with retromuscular mesh placement, using the robot.
