Popis: 357 Background: Remnant gastric cancer (RGC) is defined as a cancer arising in the remnant stomach after initial gastrectomy, regardless of the previous disease or surgical procedure. Despite growing evidence of the effectiveness of minimally invasive surgery (MIS) for primary gastric cancer, MIS for RGC remains controversial due to the rarity of the disease. This study aimed to evaluate the surgical and oncological outcomes of MIS for radical resection of RGC. Methods: We collected the data of patients with RGC who underwent surgery with curative intent between 2005 and 2020 from 17 institutions in Japan, and performed a propensity score (PS) matching analysis to compare the short- and long-term outcomes of MIS with open surgery. Results: A total of 327 patients were included in this study and 186 patients were analyzed after matching. The risk ratios for overall and severe complications were 0.76 (95% confidence interval [CI]: 0.45–1.27) and 0.65 (95% CI: 0.32–1.29), respectively. The MIS group had significantly less blood loss (50 ml vs. 361 ml, P
