Laparoscopic parenchymal-sparing hepatectomy

In their recent meta-analysis, Kalil et al. suggested that laparoscopic parenchymal-sparing hepatectomy (PSH) is associated with acceptable short-term outcomes and oncological efficiency, but they acknowledged that the quality of the available data is poor (1). During open surgery, it has long been recognised that PSH, if feasible, is superior to major hepatectomy due to significantly lower morbidity and mortality, with no differences in long-term survival (2-4).
