Comparison Of Short-Term Outcomes Of Robotic-Assisted And Laparoscopic-Assisted D2 Gastrectomy For Gastric Cancer: A Meta-Analysis

Aim: The aim of the study was to compare the outcomes of robot-assisted (RAGD2) and laparoscopy-assisted gastrectomy with D2 lymphadenectomy (LAGD2) for patients with gastric cancer.Material and methods: Relevant articles published up to September 2020 were searched. The weighted mean difference (WMD) was used to pool continuous variables, while risk ratio (RR) was calculated for dichotomous outcomes.Results: RAGD2 required a longer operating time (WMD = 29.78, 95% confidence interval (CI): 15.97-43.59) and had less operative blood loss (WMD = -31.93, 95% CI: -44.03 to -19.83), shorter time to first flatus (WMD = -0.13, 95% CI: -0.22 to -0.04), shorter time to liquid diet (WMD = -0.20, 95% CI: -0.28 to 0.12), and fewer severe complications (RR = 0.62, 95% CI: 0.43-0.90) and overall complications (RR = 0.75, 95% CI: 0.62-0.91) than LAGD2.Conclusions: RAGD2 could be beneficial in reducing operative blood loss and postoperative complications relative to LAGD2.
