Background: Although the effectiveness of robotic hepatectomy (RH) has been evaluated in several studies, the superiority of RH over other approaches has not been definitely established. Therefore, in the present propensity score–matched cohort study, we compared RH and laparoscopic hepatectomy (LH) in terms of perioperative and oncologic outcomes. Methods: This retrospective study included patients who underwent RH or LH for benign and malignant liver lesions at a single center in Taiwan at any time between 2014 and 2020. Confounding factors, specifically age, sex, body mass index, American Society of Anesthesiologists score, IWATE criteria, and Charlson comorbidity index, were adjusted through propensity score matching (PSM). Results: A total of 329 patients were finally included in this study. Two homogeneous groups (RH and LH; n, 72 each) were formed using PSM. The RH group had a longer operative time (median: 231 vs.180 min, respectively; P = .001) and lower conversion (to open surgery) rate (9.7% vs.0.0%, respectively; P = .013) than did the LH group. However, the two groups did not differ in terms of other perioperative outcomes, specifically blood loss, hospital stay, intensive care unit admission, mortality, morbidity, or tumor margin status. Conclusions: The rate of conversion to open surgery is lower in RH than in LH. Although operative time is longer in RH than in LH, RH is feasible and safe for patients with benign or malignant liver lesion. Our study also demonstrated comparable oncological results in patients with hepatocellular carcinoma between LH and RH group.
