AbstractBackground and Objectives: The feasibility of laparoscopic liver resection (LLR) for centrally located hepatocellular carcinoma (cHCC 1 cm of the hilum, major hepatic veins, and inferior vena cava) is still controversial. This study aims to evaluate the feasibility and safety of LLR for cHCC and compare the perioperative outcomes with those of open liver resection (OLR). Materials and Methods: This retrospective study included 110 patients who underwent LLR (n = 59) or open liver resection (OLR) (n = 51) for cHCC between January 2004 and September 2018. LLR group was divided into the following two subgroups according to the date of operation: Group 1 (n = 19) and Group 2 (n = 40), to account for the advancement in the laparoscopic techniques. Results: No mortality within 3 months was observed. There were no significant differences in operation time (285 vs. 280 min; p = 0.938) and postoperative complication rate (22.0% vs. 27.5%; p = 0.510) between both groups. However, intraoperative blood loss (500 vs. 700 mL; p < 0.001), transfusion rate (10.2% vs. 31.4%; p = 0.006), and hospital stay (6 vs. 10 days; p < 0.001) were significantly lower in the LLR group than in the OLR group. In the LLR group, Group 2, showed a shorter hospital stay than Group 1 (6 vs. 8 days; p = 0.006). There were improvements in the operation time (280 vs. 360 min; p = 0.036) and less intraoperative blood loss (455 vs. 500 mL; p = 0.075) in Group 2. Conclusions: We demonstrated that LLR can be safely performed in highly selected patients with cHCC.
