Abstract
The role of robotic surgery for colorectal cancer liver metastases (CRCLMs) has never been investigated in large series. A systematic literature review was carried out on PubMed and Cochrane libraries. We selected nine studies between 2008 and 2021. Two hundred sixty-two patients were included. One hundred thirty-one patients underwent simultaneous resections. The mean blood loss was 309.4ml (range, 200-450ml), the mean operative time was 250.5min (range, 198.5-449.0min). The mean length of hospital stay was 7.98 days (range, 4.5 to 12days). The overall postoperative mortality was 0.4%. The overall morbidity rate was 37.0%, Clavien-Dindo gradeIII-IV complications were 8.4%. The mean 3-year overall survival was 55.25% (range, 44.4-66.1%), the mean 3-year disease free survival was 37% (range, 33.3-41.9%) CONCLUSION: We can conclude that robotic-assisted surgery might be considered as a technical upgrade option for minimally invasive approach to CRCLM resections even for simultaneous operations and challenging cases.
