N1 - Funding Information:
This project was conducted as a project study of JSHBPS. All authors acknowledge the financial support from JSHBPS, and the endorsement from IHPBA. Details on the design of this project were decided by Go Wakabayashi, Daisuke Ban, Yuichi Nagakawa, Takao Ohtsuka, Minoru Tanabe, Masafumi Nakamura, Akihiko Tsuchida. The systematic review was supervised by Ruben Ciria, Giammauro Berardi, Hitoe Nishino, and performed by Felipe Alconchel, Keiichi Akahoshi, Shunichi Ariizumi, Andrea Benedetti Cacciaguerra, Manuel Durán, Alain García Vázquez, Nicolas Golse, Yoshihiro Miyasaka, Yasuhisa Mori, Satoshi Ogiso, Chikara Shirata, Federico Tomassini, Takeshi Urade, and Taiga Wakabayashi. Survey was conducted with the help of Filipe Kunzler. The clinical questions and recommendations were formulated and voted by 34 expert committee members; Yuta Abe, Mohammed Abu Hilal, Takeshi Aoki, Horacio J. Asbun, Giammauro Berardi, Albert CY Chan, Rawisak Chanwat, Kuo‐Hsin Chen, Yajin Chen, Daniel Cherqui, Tan To Cheung, Ruben Ciria, David Fuks, David A. Geller, Naoto Gotohda, Ho‐Seong Han, Kiyoshi Hasegawa, Etsuro Hatano, Goro Honda, Osamu Itano, Yukio Iwashita, Hironori Kaneko, Yutaro Kato, Ji Hoon Kim, Rong Liu, Santiago López‐Ben, Kazuteru Monden, Mamoru Morimoto, Fernando Rotellar, Yoshihiro Sakamoto, Atsushi Sugioka, Minoru Tanabe, Go Wakabayashi, and Tomoharu Yoshizumi. Hitoe Nishino, Shingo Kozono, Hiroaki Osakabe, and Chie Takishita contributed to the progress of this project as the secretariat. The draft of the manuscript was critiqued by all 34 expert committee members and four validation committee members; Taizo Hibi, Norihiro Kokudo, Masayuki Ohtsuka, and Masakazu Yamamoto. All authors approved the final manuscript.

N2 - Background: The Brisbane 2000 Terminology for Liver Anatomy and Resections, based on Couinaud’s segments, did not address how to identify segmental borders and anatomic territories of less than one segment. Smaller anatomic resections including segmentectomies and subsegmentectomies, have not been well defined. The advent of minimally invasive liver resection has enhanced the possibilities of more precise resection due to a magnified view and reduced bleeding, and minimally invasive anatomic liver resection (MIALR) is becoming popular gradually. Therefore, there is a need for updating the Brisbane 2000 system, including anatomic segmentectomy or less. An online "Expert Consensus Meeting: Precision Anatomy for Minimally Invasive HBP Surgery (PAM-HBP Surgery Consensus)" was hosted on February 23, 2021. Methods: The Steering Committee invited 34 international experts from around the world. The Expert Committee (EC) selected 12 questions and two future research topics in the terminology session. The EC created seven tentative definitions and five recommendations based on the experts’ opinions and the literature review performed by the Research Committee. Two Delphi Rounds finalized those definitions and recommendations. Results: This paper presents seven definitions and five recommendations regarding anatomic segmentectomy or less. In addition, two future research topics are discussed. Conclusions: The PAM-HBP Surgery Consensus has presented the Tokyo 2020 Terminology for Liver Anatomy and Resections. The terminology has added definitions of liver anatomy and resections that were not defined in the Brisbane 2000 system.
