Abstract

Minimally invasive liver surgery has evolved significantly during the last 2 decades. A growing number of published studies report outcomes from robotic liver resections (RLR). The aim of our meta-analysis was to evaluate short-term outcomes after RLR vs. open liver resection (OLR). A systematic search of Medline, Scopus, Google Scholar, Cochrane CENTRAL Register of Controlled Trials and Clinicaltrials.gov databases for articles published from January 2000 until November 2018 was performed. Ten non-randomized retrospective clinical studies comprising a total of 1248 patients were included in our meta-analysis. Four hundred and fifty-eight patients underwent RLR and 790 underwent OLR. RLRs were associated with lower overall morbidity rates (p =0.006) and shorter hospital stay (p <0.00001), whereas OLRs were associated with shorter operative time (p =0.003). No differences were shown between the two groups with regard to blood loss, blood transfusion requirements, R0 resection and mortality rates. Cumulative conversion rate was 4.6% in the RLR group. Due to limited available data, further prospective randomized studies are needed to better determine the potential beneficial role of the robotic approach in the treatment of malignant and benign hepatic tumors.
