Core Tip

Core tip: We aimed to develop a novel 3D virtual hepatectomy simulation software, Liversim, to visualize the real-time deformation of the liver. Eleven patients received virtual hepatectomies using Liversim; these virtual hepatectomies were performed both preoperatively and during actual surgery. The perioperative outcomes of the hepatectomies using Liversim were analyzed. There were no obvious discrepancies during the resection process between our simulation and the actual surgery. There were no significant differences in perioperative outcomes between the conventional 3D simulation software and the Liversim. Virtual hepatectomy with real-time liver deformation using Liversim is useful for the safe performance of hepatectomies.
