Abstrakt: Robotic distal gastrectomy (RDG) has been increasingly used for the treatment of gastric cancer, however, its comparative safety and efficacy against the laparoscopic approach (LDG), remains unclear, especially when accounting the reconstruction method as a confounder. This systematic review and meta-analysis aims to evaluate the short-term outcomes of RDG vs LDG In patIents with gastric cancer, undergoing Billroth I and II reconstruction. A systematic review was conducted in accordance with PRISMA guidelines. We searched Pubmed, Scopus and the Cochrane Library, up to October 22nd, 2024. The primary outcomes analyzed were the blood loss, operative duration, and the number of harvested lymph nodes and the secondary outcomes included overall complications, time to oral intake, duration of hospitalization and time to first flatus. Random-effects models were used to calculate weighted mean differences (WMD) and Odds ratios (OR) with 95% confidence intervals (CI), and heterogeneity was assessed using the I 2 statistic. P values were also calculated. Sensitivity analysis was performed for outcomes with moderate to high heterogeneity. Five studies were included, involving 811 patients (RDG: n = 289, LDG: n = 522). RDG was associated with a significantly longer operative duration compared to LDG (WMD = 34.14 min, 95%CI 10.92 to 57.35, P = 0.004, I 2  = 91%). RDG patients initiated oral intake earlier (WMD = -0.20 days, 95%CI -0.39 to -0.01, P = 0.03, I 2  = 45%). RDG resulted in shorter hospital stays (WMD = -1.48 days, 95%CI -2.91 to -0.04, P = 0.04, I 2  = 86%). RDG patients had a faster return to bowel function (time to first flatus) (WMD = -0.33 days, 95%CI -0.50 to -0.15, P = 0.00003, I 2  = 57%). No statistically significant differences were observed regarding blood loss between RDG and LDG (WMD = -3.88 mL, 95%CI -21.63 to 13.87, P = 0.67, I 2  = 78%). There was no statistically significant difference in complication rates (OR = 0.61, 95%CI 0.36 to 1.03, P = 0.06, I 2  = 0%). No significant differences were observed regarding the number of lymph nodes harvested (WMD = -0.49, 95%CI -3.02 to 2.04, P = 0.70, I 2  = 24%). Sensitivity analysis confirmed the robustness of the findings of operative duration and time to first flatus. RDG with BI/ BII requires longer operative duration, but it associated with faster recovery compared to LDG. No differences were observed between RDG and LDG with regards to overall complications, number of harvested lymph nodes and blood loss, showing that RDG is as safe and oncological equivalent to LDG. Future studies particularly, multi-center randomized clinical trials, should have a longer follow up period and examine the type of reconstruction separately. PROSPERO registration: CRD42024605895.
