A case matched analysis from the IMIGASTRIC database to compare robotic, laparoscopic and open

Objectives The aim of this study was to compare different surgical approaches during a D2 gastrectomy. The IMIGASTRIC database was used to analyze short - term and long - term data. This is a comparative study on three treatment arms. Data were extracted from the IMIGASTRIC database considering only D2 procedures. Then a propensity score matching was performed to reduce potential selection bias. After assessment of inclusion and exclusion criteria and propensity score matching, a total of 1142 patients were analyzed: 258 in the robotic group, 258 in the laparoscopic group, and 626 in the open group. Among the main outcomes operative time, estimated blood loss, hospital stay had a statistical significant difference (P<0.001). The median follow - up time was 24 months. Kaplan-meiers curves of survival didn't show differences. Overall survival rates at 2, 3 and 5 years were 90%, 85% and 60% in the robotic group, 93%, 88% and 64% in the laparoscopic group, 86%, 81% e 56% in the open group. This study compared a large sample of patients showing differences in perioperative results and similar survival at the oncological follow-up.
