Study Description

Brief Summary: Despite the worldwide increase of both obesity and use of minimally invasive liver surgery(MILS), evidence regarding the safety and eventual benefits of MILS in obese patients is scarce. The aim of this study is therefore to compare the outcomes of non-obese and obese patients(BMI 18.5-29.9 and BMI≥30, respectively) undergoing MILS and OLS, and to assess trends in MILS use among obese patients. In this retrospective cohort study, patients operated at 20 hospitals in eight countries(2009-2019) will be included and the characteristics and outcomes of non-obese and obese patients will be compared. Thereafter, the outcomes of MILS and OLS were compared in both groups after propensity-score matching(PSM). Changes in the adoption of MILS during the study period will be investigated.
