Abstract: Background: As an emerging technology, robot-assisted surgical system has some potential merits in many complicated endoscopic procedures compared with laparoscopic surgery. But robot-assisted liver resection is still a controversial problem on its advantages compared with laparoscopic liver resection. We aimed to perform the meta-analysis to assess and compare the clinical outcomes of robot-assisted and laparoscopic liver resection. Methods: We searched PubMed, Cochrane Library, Embase databases, Clinicaltrials, and Opengrey through March 24, 2020, including references of qualifying articles. English-language, original investigations in humans about robot-assisted and laparoscopic hepatectomy were included. Titles, abstracts, and articles were reviewed by at least 2 independent readers. Continuous and dichotomous variables were compared by the weighted mean difference (WMD) and odds ratio (OR), respectively. Results: Of 936 titles identified in our original search, 28 articles met our criteria, involving 3544 patients. Compared with laparoscopy, the robot-assisted groups had longer operative time (WMD: 36.93; 95% CI, 19.74–54.12; P
