Defining Global Benchmarks for Laparoscopic Right Posterior Sectionectomy/H67: An International Multicenter Study.

Area of Science:

• Hepatobiliary Surgery
• Minimally Invasive Surgery
• Surgical Outcomes Research

Background:

• Minimally invasive liver resections are increasingly adopted.
• Laparoscopic right posterior sectionectomy (L-RPS/H67) is a challenging procedure gaining traction.

Purpose of the Study:

• Establish global benchmark outcome indicators for L-RPS/H67.
• Provide a reference for surgical auditing and performance evaluation.

Main Methods:

• Post hoc analysis of a multicenter database (854 patients, 57 centers, 4 continents, 2015-2021).
• Included pure L-RPS and robotic RPS (R-RPS) cases.
• Selected 16 outcome indicators for low-risk L-RPS cases.
• Set benchmark cutoffs using the 75th percentile of individual center medians.

Main Results:

• Analyzed 573 L-RPS/H67 from 43 expert centers; 254 (44.3%) were low-risk benchmark cases.
• Established benchmarks for operation time (350.8 min), open conversion (12.5%), blood loss ≥500 mL (53.8%), transfusion (22.9%), morbidity (23.8%), major morbidity (2.8%), 90-day mortality (0%), and textbook outcome (4%).

Conclusions:

• The study presents the first global benchmark values for L-RPS/H6/7.
• These benchmarks serve as an up-to-date reference for surgical auditing and benchmarking best achievable outcomes.
