To validate the Iwate difficulty scoring system and Institut Mutualiste Montsouris (IMM) scoring system (Appendix 2) in both laparoscopic and robotic liver resections
Minimally-invasive liver resections (MILR) are increasingly conducted world-wide today. Several international consensus meetings were convened to enable the safe dissemination of laparoscopic and robotic liver resections. The Iwate difficulty scoring system (Appendix 1) was formulated in Japan to grade the difficulty of liver resections. This was to allow beginners to adopt a stepwise approach to safely perform MILR according to their experience and competency level. Although this system has been recently validated in a recent Japanese multicenter study, it has not been externally validated in a large cohort of patients. Thus far, it has only been validated in several small single center studies. Furthermore, its utility for robotic liver resections has not been well-studied.
2,081 studies on the registry are indexed under Liver Diseases; 389 are open to participants now.
This study's planned enrollment of 150 is below the median of 167 across 681 observational studies indexed under Liver Diseases.

laparoscopic and robotic liver resections
Iwate scores for laparoscopic and robotic liver resections
To validate the Iwate difficulty scoring system IMM scoring system in both laparoscopic .and robotic liver resections. The IWATA measures the difficulty index from 0 to 12. The IMM scoring is from code 1 to 11.
Time frame: January 1, 2000 to December 31, 2020
Propensity scores for robotic and laparoscopic liver resections
To perform a propensity score matching (including adjustment for difficulty) comparing robotic and laparoscopic liver resections.
Time frame: January 1, 2000 to December 31, 2020
