OBJECTIVE: A large-scale multicenter retrospective cohort study was conducted to compare the short- and long-term outcomes of robotic gastrectomy (RG) and laparoscopic gastrectomy (LG) for gastric cancer. SUMMARY OF BACKGROUND DATA: RG is being increasingly used worldwide, but data from large-scale multicenter studies on the short- and long-term oncologic outcomes of RG versus LG are limited. The potential benefits of RG compared with LG for gastric cancer remain controversial. METHODS: Data from eligible patients who underwent RG or LG for gastric cancer of 11 experienced surgeons from 7 centers in China between March 2010 and October 2019 were collected. The RG group was matched 1:1 with the LG group by using propensity score matching. The primary outcome was postoperative complications. RESULTS: After propensity score matching, a well-balanced cohort of 3552 patients was included for further analysis. The occurrence of overall complications (12.6% vs 15.2%, P = 0.023) was lower in the RG group than in the LG group. RG was associated with less blood loss (126.8 vs 142.5 mL, P < 0.001) and more retrieved lymph nodes in total (32.5 vs 30.7, P < 0.001) and in suprapancreatic areas (13.3 vs 11.6, P < 0.001).The long-term oncological outcomes were comparable between the two groups. CONCLUSIONS: The results of this multicenter study demonstrate that RG is a safe and effective treatment for gastric cancer when performed by experienced surgeons, although longer operation time and h...
