The beginnings of laparoscopic liver resection(LLR)were at the start of the 1990s,with the initial reports being published in 1991 and *** were followed by reports of left lateral sectionectomy in *** the years following,the procedures of LLR were expanded to hemi-hepatectomy,sectionectomy,segmentectomy and partial resection of posterosuperior segments,as well as the parenchymal preserving limited anatomical resection and modified anatomical(extended and/or combining limited)resection *** expanded range of LLR procedures,mimicking the expansion of open liver resection in the past,was related to advances in both technology(instrumentation)and technical skill with conceptual *** this period of remarkable development,two international consensus conferences were held(2008 in Louisville,KY,United States,and 2014 in Morioka,Japan),providing up-to-date summarizations of the status and perspective of *** advantages of LLR have become clear,and include reduced intraoperative bleeding,shorter hospital stay,and-especially for cirrhotic patients-lower incidence of complications(e.g.,postoperative ascites and liver failure).In this paper,we review and discuss the developments of LLR in operative procedures(extent and style of liver resections)during the first quarter century since its inception,from the aspect of relationships with technological/technical developments with conceptual changes.
