Reply to: The letter to the editor "Laparoscopic liver resection for malignancies confined to Couinaud's segment VII in the robotic surgery era" by Zizzo et al.

We would like to thank you and other reviewers for reading our papers and sharing valuable comments. We are also appreciative of your conscientiousness and broad knowledge on relevant research fields. Recent advances in robotic hepatectomy (RH) were briefly summarized in your letter, especially its non-inferiority compared with the conventional laparoscopic liver resection (LLR). Here, we would like to address several points relevant to the comments.
