Abstract
BACKGROUND: To date, there are few studies comparing the outcomes of robotic hepatectomy (RH) versus open hepatectomy (OH). We report the first systematic review and meta-analysis comparing the outcomes of RH versus OH. METHODS: A systemic review was performed of all comparative studies of RH versus OH that reported the perioperative outcome(s) of interest. RESULTS: Seven retrospective cohort studies were included. There was no significant difference in patients' baseline characteristics. RH was associated with a longer operation time (mean difference (MD) 61.47 min; 95% confidence interval (CI) (7.03, 115.91); P = 0.03), shorter hospital stay (MD -2.57 days; 95% CI (-3.31, -1.82); P < 0.001), lower costs, less overall (risk ratio (RR) 0.63; 95% CI (0.46, 0.86); P = 0.004), minor (RR 0.64; 95% CI (0.43, 0.95); P = 0.03) and major (RR 0.45; 95% CI (0.22, 0.94); P = 0.03) post-operative complications compared to OH. CONCLUSION: RH had superior perioperative outcomes and was not cost prohibitive compared to OH, but had longer operation times.
