BACKGROUND: Accurate assessment of the future liver remnant (FLR) is crucial for predicting the risk of post-hepatectomy liver failure (PHLF). This survey aims to evaluate the current practices of liver surgeons regarding FLR volumetry and its clinical use. METHODS: A cross-sectional survey was conducted among 212 liver surgeons to assess their use of FLR volumetry and associated methodologies. The survey consisted of 40 questions distributed in five sections covering multiple aspects of FLR volumetry. RESULTS: Ninety percent of respondents utilize preoperative FLR volumetry. However, there is significant variability in the methods used for FLR calculation and the thresholds for safe liver resection, which deviate from the proposed 20/30/40 % rule. Before right hepatectomy, 21 % of respondents indicated that they rarely or never utilise volumetry. Extended resections are the surgical procedures in which volumetry is most frequently employed. Furthermore, the kinetic growth rate is not widely adopted in clinical decision making. CONCLUSION: This survey highlights the widespread use of FLR volumetry, but also reveals substantial variation in its application. This demonstrates a lack of evidence or guidelines regarding the appropriate use of FLR volumetry.
