“…Compared to OLR, the chance of long-term survival after LLR remains controversial [ 26 , 27 ]. There was initial concern that LLR would decrease the tumor-free surgical margin because of the lack of palpation, as tumor-free surgical margins affect disease-free survival after resection of HCC [ 25 , 28 ].…”

Background: Short-term outcomes of laparoscopic hepatectomy of central-located liver lesions (LHCL) compared with traditional open hepatectomy of central-located liver lesions (OHCL) remain unclear. The aim of this study was to explore the safety and efficacy of LHCL. Methods: A retrospective analysis was performed on 262 patients who underwent hepatectomies involving resections of liver segment II, IV or VIII from January 2015 to June 2021 in two institutions. Patients in the LHCL group were matched in a 1:2 ratio to patients in the OHCL group. Results: After propensity score-matched (PSM) analysis, 61 patients remained in the LHCL group and 122 patients were in the OHCL group. What needs to be mentioned is that although not significant, patients in the OHCL group had increased lesion size (4.3 vs. 3.6 cm, p = 0.052), number (single/multiple, 84.8%/15.2% vs. 93.4%/6.6%, p = 0.097), and number of liver segments involved (one/two/three, 47.3%/42.0%/10.7% vs. 57.4%36.1%/10.7%, p = 0.393). To ensure surgical safety, fewer patients in the LHCL group underwent vascular exclusion than those in the OHCL group (p = 0.004). In addition, LHCL was associated with lower blood loss (p = 0.001) and transfusion requirement (p = 0.004). In terms of short-term outcomes, the LHCL group had significantly lower levels of peak ALT (p < 0.001), peak DBIL (p = 0.042), peak PT (p = 0.012), and higher levels of bottom ALB (p = 0.049). Moreover, the LHCL group demonstrated quicker postoperative recovery, which was represented by shorter time to first flatus, time to oral intake, time to drain off, and hospital stay (all p < 0.001). Importantly, the LHCL group had a significantly reduced occurrence of postoperative complications (p < 0.001) and similar R0 resection rates (p = 0.678) when compared to the OHCL group. Conclusion: LHCL is associated with increased safety and better perioperative outcomes and thus could be recommended for patients with central space-occupying liver lesions when appropriately selecting the surgical procedure according to the total tumor burden and carefully handled by experienced surgeons. From the experience of our center, LHCL could be performed to solitary lesion involving liver segment IV/V/VIII, <5 cm, with good safety and feasibility.
