[Current robotic ventral hernia surgery exemplified by 50 consecutive patients].

Background: In recent years there has been a rise in robotic techniques and approaches regarding hernia repair with extraperitoneal mesh placement.

Methods: A retrospective analysis of the first 50 patients who underwent robotic ventral hernia repair between May 2019 and November 2020 at the department of general surgery of the Kempten Clinic was performed.

Results: This case series consisted of 36 incisional hernias, 12 primary hernias (8 umbilical and 3 epigastric hernias in combination with a diastasis recti abdominis as well as 1 Spigelian hernia) and 2 parastomal hernias. A complete closure of the hernia was achieved in all cases. Extraperitoneal mesh placement in the retromuscular or preperitoneal space was achieved in 98 % of the ventral procedures. We used an extraperitoneal approach with retromuscular mesh implantation (r-eTEP= robotic enhanced view total extraperitoneal plasty) in 22 cases, 3 of those along with a transversus abdominis release (r-eTAR= robotic extraperitoneal transversus abdominis release) and 26 operations were carried out transperitoneally. These included 11 preperitoneal (r-vTAPP= robotic ventral TAPP), 7 retrorectus (TARUP= robotic transabdominal retromuscular umbilical prosthetic hernia repair) and 1 intraperitoneal onlay mesh placements (r-IPOM= robotic intraperitoneal onlay mesh) as well as 7 transperitoneal transversus abdominis releases with retromuscular mesh placement. The 2 parastomal hernias were treated with an intraperitoneal 3D funnel mesh. After the initial treatment of smaller hernias the indications could be rapidly extended to complex hernias in 38 % of this case series. One conversion to an open operation was necessary due to technical problems in closing the posterior rectus sheath. The complication rate was 12 % and the reintervention rate 4 %.

Conclusion: Robotic surgery of ventral hernia is safe and effective. Even complex hernias can be treated minimally invasively with closure of the hernia defect and extraperitoneal mesh placement.
