Abstract

Introduction: Currently, the impact of body mass index (BMI) on the outcomes of laparoscopic liver resections (LLR) is poorly defined. This study attempts to evaluate the impact of BMI on the peri-operative outcomes following laparoscopic left lateral sectionectomy (L-LLS). Methods: A retrospective analysis of 2183 patients who underwent pure L-LLS at 59 international centers between 2004 and 2021 was performed. Associations between BMI and selected peri-operative outcomes were analyzed using restricted cubic splines. Results: A BMI of >27kg/m2 was associated with increased in blood loss (Mean difference (MD) 21 mls, 95% CI 5–36), open conversions (Relative risk (RR) 1.13, 95% CI 1.03–1.25), operative time (MD 11 min, 95% CI 6–16), use of Pringles maneuver (RR 1.15, 95% CI 1.06–1.26) and reductions in length of stay (MD -0.2 days, 95% CI -0.3 to −0.1). The magnitude of these differences increased with each unit increase in BMI. However, there was a “U” shaped association between BMI and morbidity with the highest complication rates observed in underweight and obese patients. Conclusion: Increasing BMI resulted in increasing difficulty of L-LLS. Consideration should be given to its incorporation in future difficulty scoring systems in laparoscopic liver resections.
