Are the current difficulty scores for laparoscopic liver surgery telling the whole story? An international survey and recommendations for the future

摘要

Background: Recent studies have suggested that the difficulty of laparoscopic liver resections are related to both patient and tumour factors, however the available difficulty scoring systems only incorporate tumour factors. The aim of this study was to assess the opinion of laparoscopic liver surgeons regarding the factors that affect the perceived difficulty of laparoscopic liver resections.
