A comparative study on Da Vince robotic and laparoscopic radical gastrectomy for gastric cancer

Objective To compare the short-term surgical outcomes of robotic-assisted gastrectomy versus laparoscopic-assisted procedures for gastric cancer patients. Method From 2014 to 2018, 108 robotic procedures and 263 laparoscopic surgery were done at Affiliated Hospital of Qingdao University. Results Compared with the laparoscopic group, the robotic group had longer operation time [(269±32) min vs. (205±30) min, t=18.314, P 0.05], the proximal margin [(5.7±1.1) cm vs.(5.4±1.2) cm, t=1.583, P>0.05]and distal tumor margin [(4.7±2.1) cm vs.(4.9±2.0) cm, t=0.848, P>0.05]; There were no significant differences in the incidence of complications (13.9%vs.15.2%, χ2=0.106, P>0.05)and grade by Clavien-Dindo operation complications(Z=-0.271, P>0.05) between the two groups. Conclusion Da Vinci robotic radical gastrectomy is safe, better than laparoscopic procedure in intraoperative manipulation. Key words: Stomach Neoplasms; Robotics; Laparoscopy; Gastrectomy
