Abstract: Preoperative planning, a prerequisite for proper implementation of laparoscopic anatomical hepatectomy, mainly includes individual vascular territorial analysis, determination of surgical approach, confirmation of anatomical landmarks, and selection of techniques and insturments required. Understanding of the surgery-related anatomy of the liver is crucial for surgical planning. This review enumerates the limitations of the existing Couinaud’s segmentation and proposes a novel liver segmentation method according to subsegmental characteristics of inflow and outflow pathways of the liver based on 3D image reconstruction. We also aim to evaluate the surgical approaches and key anatomical landmarks of each subsegment in its surgical planning for anatomial resection.
