Abstract Background Robotic-assisted surgery (RAS) is increasingly used for colorectal cancer (CRC), but its clinical and oncologic advantages over conventional laparoscopy (LS) remain uncertain. Prior meta-analyses (e.g., Huang et al., Front Oncol 13;1273378, 2023; Zou et al., BMC Surg 25;86, 2025) have included overlapping RCTs but vary in methodology, scope, and analytical transparency. This review aims to provide an updated, independently re-analyzed synthesis of RCTs published from 2015 to 2025, with full PRISMA compliance, explicit analytic reproducibility, and expanded evaluation of bias and evidence certainty. Methods A systematic review and meta-analysis was conducted according to PRISMA guidelines. The protocol was retrospectively registered in PROSPERO (Registration ID: CRD420251237158 ). PubMed, Embase, and Cochrane CENTRAL were searched (January 1, 2015–January 31, 2025). Full reproducible search strings, PICOS criteria, and inclusion/exclusion rules were predefined. O
