Defining Global Benchmarks for Laparoscopic Right Posterior Sectionectomy/H67

Abstract

Objective:To establish global benchmark outcomes indicators for laparoscopic right posterior sectionectomies (L-RPSs)/H67.Background:Minimally invasive liver resections have seen an increase in uptake in recent years. Over time, challenging procedures such as L-RPS/H67 are also increasingly adopted.Methods:This is a post hoc analysis of a multicenter database of 854 patients undergoing minimally invasive RPS in 57 international centers in 4 continents between 2015 and 2021. There were 651 pure L-RPS and 160 robotic RPS. Sixteen outcome indicators of low-risk L-RPS cases were selected to establish benchmark cutoffs. The 75th percentile of individual center medians for a given outcome indicator was set as the benchmark cutoffResults:There were 573 L-RPS/H67 performed in 43 expert centers, of which 254 L-RPS/H67 (44.3%) cases qualified as low-risk benchmark cases. The benchmark outcomes established for operation time, open conversion rate, blood loss >= 500 mL, blood transfusion rate, postoperative morbidity, major morbidity, 90-day mortality, and textbook outcome after L-RPS were 350.8 minutes, 12.5%, 53.8%, 22.9%, 23.8%, 2.8%, 0%, and 4%, respectively.Conclusions:The present study established the first global benchmark values for L-RPS/H6/7. The benchmark provided an up-to-date reference of the best achievable outcomes for surgical auditing and benchmarking.
