Comparing robotic and open surgical techniques in gallbladder cancer management: a detailed systematic review and meta-analysis

This meta-analysis aims to evaluate the safety and oncological outcomes of robotic surgery compared to open surgery in treating gallbladder cancer (GBC). In October 2023, we performed a literature search across major global databases such as PubMed, Embase, and the Cochrane Library. We employed a Review Manager for parameter comparisons. This study has been registered with PROSPERO under the identifier CRD42023476686. Our final meta-analysis incorporated 5 cohort studies, encompassing a total of 353 patients. Compared to the Open Group (OG), the Robotic Group (RG) had reduced intraoperative blood loss (WMD − 217.72 ml, 95% CI − 371.08 to − 64.35; p = 0.005), shorter hospital stay (WMD − 1.80 days, 95% CI − 2.66 to − 0.95; p
