Anatomical right superior segmentectomy has always been a difficult surgical procedure in laparoscopic liver resection. How to accurately judge the interface between liver segments, so as to achieve a true sense of anatomic resection based on portal territory is a new requirement in the era of precision liver surgery. The portal vein puncture and indocyanine green (ICG) fluorescence positive staining technique can effectively solve this problem, which has a series of advantages and certain technical requirements in anatomical right superior segmentectomy. ICG fluorescence staining can intuitively define the three-dimensional range of the liver segment, which is a more accurate navigation mode that helps liver surgeons identify the range of the right superior liver segment, thus conducting surgery more safely and normatively. The authors consult relevant studies and combined with clinical practice to explore the application value of laparoscopic ultrosound guided puncture and positive staining technique in anatomical right superior segmentectomy.
