Robotic versus laparoscopic major hepatectomy for hepatocellular carcinoma: short-term outcomes from a single institution

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. 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. 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
