Core Tip

Core Tip: We achieved laparoscopic anatomical segmental or subsegmental liver resection through our novel techniques. Using this method, we can access the hepatic pedicle of each individual cone unit and perform resection of the portal vein basin associated with that cone unit. And we standardize the detailed steps of anatomical hepatic resection and show the acquisition of key points. It has a positive effect on the promotion and development of anatomical liver resection worldwide.
