Open vs robotic gastrectomy with D2 lymphadenectomy: a propensity score-matched analysis on 1469 patients from the IMIGASTRIC prospective database

Background Comparative data on D2-robotic gastrectomy (RG) vs D2-open gastrectomy (OG) are lacking in the Literature. Aim of this paper is to compare RG to OG with a focus on D2-lymphadenectomy. Study design Data of patients undergoing D2-OG or RG for gastric cancer were retrieved from the international IMIGASTRIC prospective database and compared. Results A total of 1469 patients were selected for inclusion in the study. After 1:1 propensity score matching, a total of 580 patients were matched and included in the final analysis, 290 in each group, RG vs OG. RG had longer operation time (210 vs 330 min, p
