Preliminary robotic abdominal wall reconstruction experience: single-centre outcomes of the first 150 cases.

PURPOSE: Robotic surgery offers new possibilities in repairing complex hernias with a minimally invasive approach. This study aimed to analyze our preliminary results. METHODS: Between November 2015 and February 2020, 150 patients underwent robotic reconstruction for abdominal wall defects (77 primary and 73 incisional). A retrospective analysis of a prospectively maintained database was conducted to evaluate the short-term outcomes. RESULTS: The mean operative time was 176.9 ± 72.1 min. No conversion to open or laparoscopic approach occurred. The mean hospital length of stay was 2.6 ± 1.6. According to Clavien-Dindo classification, two (grade III) complications following retromuscular mesh placement (1.3%) occurred. One patient (0.7%) required surgical revision due to small bowel occlusion following an intraparietal hernia. The 30-day readmission rate was 0.6%, and the mortality was nihil. CONCLUSIONS: Robotic surgery is valuable for safely completing challenging surgical procedures like complex abdominal wall reconstruction, with low conversion and complication rates. A stepwise approach to the different surgical techniques is essential to optimize the outcomes and maximize the benefits of the robotic approach.

Robot-assisted treatment of splenic artery aneurysms.

BACKGROUND: Although splenic artery aneurysms (SAAs) are relatively uncommon, they are clinically relevant because of the risk of rupture. Optimal management is a matter of debate and involves the use of percutaneous endovascular stenting, which has limitations, versus the open surgical approach which can lead to significant morbidity. The present study reports the outcomes of robot-assisted surgery for SAA and its role in overcoming many of the limitations of laparoscopy. METHODS: A total of nine patients with incidentally detected SAAs underwent a surgery between September 2001 and November 2007. Six of these nine patients underwent a robot-assisted splenic aneurysm resection with vascular reconstruction. The remaining three cases included one robotic arterial ligation, one robotic partial splenectomy, and one laparoscopic splenectomy. RESULTS: The mean operating time was 212 ± 61 minutes (range: 90-300), mean intraoperative blood loss was 186.6 ± 202.4 mL (range: 0-500), and mean hospital stay was 7.1 ± 3.7 days (range: 3-14). The morbidity rate was 11.1% and no mortality was reported. Doppler-ultrasonography surveillance showed regular organ perfusion in all patients with vascular reconstruction. CONCLUSION: Robot-assisted surgery for SAA represents one of the most advanced developments among minimally invasive procedures and can become an important option for the treatment of this disease.

Retromuscular Mesh Repair Using Extended Totally Extraperitoneal Repair Minimal Access: Early Outcomes of an Evolving Technique-A Single Institution Experience.

Background: Enhanced-view extended totally extraperitoneal repair (eTEP) technique for laparoscopic retromuscular ventral hernia (VHR) repair is a novel application recently described by some authors. We present our early single institution experience on this technique. Methods: Retrospective review of the eTEP technique for laparoscopic retromuscular VHR repair cases at our institution from October 2018 to June 2019 with 1 month follow-up was evaluated. Data analyses include patients characteristics, operative details, and complications. Results: A total of 18 patients were treated with eTEP. One patient was reoperated using the same procedure and hospital stay was 6 days. The same patient who had undergone transversus abdominis release developed a seroma that could be observed 20 days after surgery. Conclusion: Our short-term experience with eTEP access suggests feasibility of this approach in accordance with results from other authors. We do not think the technique is challenging, but it is necessary for it to be performed by surgeons with skills in laparoscopic abdominal wall reconstruction.
