| Core Tip |
This study proposes a portal vein-based subsegmental classification of liver segment 4 (S4) derived from preoperative imaging and three-dimensional reconstruction. Intermediate branches crossing the falciform ligament were frequently identified, suggesting that the conventional boundary of S4 may not fully reflect its true portal territory. The proposed framework may support individualized parenchyma-sparing laparoscopic resection, particularly for type II anatomy. In the exploratory comparative follow-up dataset, no significant difference in overall survival or progression-free survival was observed between the Novel and Conventional groups. Formal validation remains necessary. |
