Level 2a evidence comparing robotic versus laparoscopic left lateral hepatic sectionectomy: a meta-analysis.

Meta-analysis of the best available evidence (level 2) demonstrated that robotic LLS is associated with significantly longer procedure time and higher cost and similar perioperative outcomes compared to the laparoscopic approach. Future randomised studies are required to evaluate short-term perioperative, long-term oncological and surgeon-centred outcomes.
