Volume–outcome relationship in anatomical and non-anatomical liver resections: a rapid systematic review

The findings provide evidence supporting a positive association between higher hospital volume and improved patient-relevant outcomes in liver resection. However, surgeon volume remains underexplored and the evidence from subgroups indicates that the impact of hospital or surgeon volume likely depends on study quality, procedure type, volume thresholds, and respective outcome parameters. Patient care could benefit from further research on long-term outcomes as well as quality of life, for which the current evidence is scarce.
