Objective:To formulate surgical strategies and guide the implementation of laparoscopic anatomical hepatectomy with preoperative simulative resection.Methods:Twenty-two cases of hepatocellular carcinoma undergoing laparoscopic lobe, segment, subsegment and combined segment liver resection following preoperative simulative resection from Sep 2020 to Jan 2022 were enrolled in this study retrospectively.We observed and analyzed the operation time,intraoperative blood loss,postoperative hospital stay and postoperative complication.Results:All patients underwent laparoscopic hepatectomy successfully according to the preoperative simulative resection plan without conversion, some of them adjusted plan according to preoperative simulative resection. The median operation time was 170.0 min, the median intraoperative blood loss was 150.0 ml, the median times of pringle maneuver was done on 4 episodes, and the median postoperative hospital stay was 6.5 days. There were no severe postoperative complications in all cases.Conclusion:Preoperative simulative resection can plan the range of surgical resection accurately by visualizing important anatomical structures,greatly helping the actual surgical hepatectomy.
