We read with great interest the article written by Nota et al. (1) comparing the perioperative results of robotic (RLR) versus open (OLR) minor liver resections of postero-superior (PS) segments with a propensity score based analysis. Data from four international institutions, from both Western and Eastern centres, were compared. The authors demonstrated that minor RLRs of the PS segments, when performed in selected patients in referral centres, are safe, feasible and also characterized by a shorter length of hospital stay compared to the OLRs. Although this analysis provides valuable data, we would like to highlight some aspects that have been underestimated by the authors.
