This study aimed to describe a simple and novel positional classification system for centrally located hepatocellular carcinoma (CL-HCC), based on which different surgical approaches for laparoscopic mesohepatectomy (LMH) were chosen. The data of patients with CL-HCC who underwent LMH between January 2017 and December 2021 were retrospectively analyzed. The positional classification method was used to locate tumors. In addition, different approaches were used during the surgery according to the classification type. All 98 patients underwent LMH, of whom 4 were converted to open surgery. Types I, Ⅱ, and Ⅲ were 24, 37, and 37, respectively. Blood transfusions were performed in only 7 patients, of which the amount was 800 (600, 900) mL. All the patients underwent R0 resection. The complication rate was 9.2 in all cases. No deaths occurred. Our proposed classification system and corresponding surgical approach in LMH is conducive to the successful completion of surgery.
