Abstract
Background: The authors present their experience of robotic liver resections in comparison with open technique. Methods: Retrospective review of liver resections done robotically from February 2015 to June 2017 compared to matched control cohort of open cases from January 2012 to December 2016. Results: Seventeen patients in the study group were compared with matched control of 34 open cases (1:2 ratio). The type of procedure were similar in both groups, there were five left lateral hepatectomy, two left hepatectomy, and one left hepatectomy with hepatico-jejunostomy, one right hepatectomy, one right posterior sectorectomy, four bisegmentectomy and three mono-segmentectomy. Mean operative duration was 442 ± 135 minutes in the robotic compared to 357 ± 127 minutes in control group (p = 0.03). Mean blood loss was 270 ± 311 ml in the robotic compared to 451 ± 330 ml in control group (p = 0.06). Minor complications developed in 17% of robotic cases compared to 41% in open surgery (p = 0.5), while major complications occurred in 5.8% of robotic cases compared to 8.8% of open (p = 0.3). Mean hospital stay was 5.35 ± 0.8 days for the robotic group and 7.7 ± 4.2 days for open group (p = 0.02). Conclusion: This study highlights the utility of robotics for liver resections with equivalent outcomes and decreased length of stay compared to open surgery.
