Abstract Background Currently, an increasing number of robotic major hepatectomies for hepatocellular carcinoma (HCC) are being performed. Despite the advantages of robotic surgery over laparoscopic procedures, studies comparing robotic with laparoscopic major hepatectomy in terms of short-term results remain scarce. This study was performed to compare robotic major hepatectomy and laparoscopic major hepatectomy in terms of their intraoperative and postoperative results. Methods Data regarding demographics and intraoperative and postoperative results of 131 patients undergoing robotic or laparoscopic major hepatectomy between January 2017 and March 2022 were retrieved from their medical records and compared between the two types of surgery. Results Between January 2017 and March 2022, 44 robotic major hepatectomies and 87 laparoscopic major hepatectomies were performed at the Department of Hepatobiliary and Pancreatic Surgery, Shenzhen People’s Hospital. Patients undergoing robotic major hepatectomy were not significantly different from those undergoing laparoscopic major hepatectomy in terms of age (P = 0.397), sex (P = 0.624), body mass index (BMI) (P = 0.118), alpha-fetoprotein (AFP) (P = 0.09), tumor size (P = 0.176), cirrhosis (P = 0.384), fatty liver (P = 0.162), preoperative antiviral treatment (P = 0.934), hepatitis B virus (HBV) DNA (P = 0.646) and operation type (P = 0.054). Robotic major hepatectomy was associated with a longer operation time (median: 255.5 versus 206.8 min; P < 0.001) and less estimated blood loss (median: 118.9 versus 197.0 ml; P = 0.002) than laparoscopic major hepatectomy. However, robotic major hepatectomy was not significantly different from laparoscopic major hepatectomy regarding length of postoperative hospital stay (P = 0.849), open conversion (P = 0.077), ICU stay (P = 0.866), postoperative massive abdominal bleeding (P = 1.00), portal vein thrombosis (P = 1.00), abdominal infection (P = 1.00), pulmonary infection (P = 1.00), pulmonary embolism (P = 1.00), cardiac complications (P = 1.00), liver failure (P = 1.00), kidney failure (P = 1.00), biliary leak (P = 1.00), positive resection margin (P = 1.00), 30-day mortality (P = 1.00) and 90-day mortality (P = 1.00). Conclusions Robotic major hepatectomy was as effective as laparoscopic surgery in terms of intraoperative and postoperative results but took longer and could more efficiently control intraoperative blood loss.
