The beginnings of laparoscopic liver resection (LLR) were at the start of the 1990s, with the initial reports being published in 1991 and 1992. These were followed by reports of left lateral sectionectomy in 1996. 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 procedures. This 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 changes. During 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 LLR. The 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.
Core tip: Laparoscopic liver resection (LLR) was introduced in early 1990s. Thereafter, LLR procedures have expanded to left lateral sectionectomy, hemi-hepatectomy, sectionectomy, segmentectomy and partial resection of posterosuperior segments, as well as parenchymal preserving limited and modified anatomical resection. This expansion is related to technological/technical developments with conceptual changes. During this period, two international consensus conferences summarized the up-to-date status and perspective of LLR. The current advantages of LLR include reduced intraoperative bleeding, shorter hospital stay, and lower incidence of complications. Here, we review and discuss the developments of LLR in operative procedures during the first quarter century since its inception.
