Robotic liver surgery for metastatic disease: A review of safety, feasibility, and outcomes

BACKGROUND
Colorectal cancer is the third most common malignancy globally, with the liver
being the predominant site of metastatic disease.
AIM
To evaluate safety, feasibility, and outcomes of robotic liver resection (RLR) versus
laparoscopic liver resection (LLR) and open liver resection (OLR) for colorectal
metastasis (CRLM).
METHODS
This study followed Preferred Reporting Items for Systematic reviews and MetaAnalyses guidelines. Systematic searches in PubMed, EMBASE, Scopus, and
Cochrane Library identified comparative and noncomparative reviews evaluating
RLR versus LLR or OLR for CRLM. Two independent reviewers screened studies
using predefined PICO (Population, Intervention, Comparator, Outcome) criteria,
with data extraction focusing on conversion rates, operative outcomes, morbidity,
mortality, and survival. Methodological quality was assessed via Assessment of
Multiple Systematic Reviews 2. Pooled analyses were performed for comparative
