Abstract Anatomical liver resection was an option for liver cancer proposed by the Japanese scholar Masatoshi Makuuchi in 1985 [1]. Reich et al. performed the first laparoscopic liver resection in 1991 [2]. The safety and effectiveness of laparoscopic anatomical liver resection had been verified in recent years [2–4] . However, laparoscopic anatomical segment VII liver resection (LAS7) was the most difficult procedure because of complex adjacent structures, difficult exposure, and limited laparoscopic view [3,5]. Therefore, the LAS7 had only been explored in some large national and international medical centers. Ishizawa et al. [3] reported a surgical protocol to resect segment VII of the liver that included parenchymal separation from the foot to the head side, which was identical to open anatomical liver resection. However, the liver pedicle of segment VII is difficult to locate and ligate precisely; and it is difficult to show the ischemic demarcation line completely. Herein we implemented a new, convenient approach for precise liver resection that can be used during LAS7.
