1228. Comparison of surgical site infection between open and robotic-assisted gastrectomy in patients with gastric cancer

Abstract

Abstract Background Surgical site infection is a clinically significant postoperative complication and a major cost burden of healthcare-associated infections. Although many studies compare minimally invasive surgery and open surgery, few studies have focused on surgical site infection. This study aimed to investigate the differences in the incidence of surgical site infection after open and robotic-assisted gastrectomy in patients with gastric cancer. Methods We retrospectively reviewed adult patients with gastric cancer who underwent open and robotic-assisted gastrectomy at a 2,400-bed tertiary hospital in Seoul from January 2015 to December 2015. Postoperative outcomes, including surgical site infection between open and robotic-assisted gastrectomy, were compared. Risk factors of surgical site infection were analyzed by logistic regression multivariable analysis. Results A total of 684 patients, including 448 patients who underwent open gastrectomy and 236 patients who underwent robotic-assisted gastrectomy, were enrolled. The median age was 58 years. The overall incidence of surgical site infection was 7.6%. The incidence of surgical site infection was significantly lower in the robotic-assisted gastrectomy group than in the open gastrectomy group (9.2% vs. 4.7%, p=0.035). The length of hospital stay was significantly shorter in the robotic-assisted gastrectomy group than in the open gastrectomy group (5 vs. 8 days, p< 0.001). Multivariate logistic regression revealed that the operative time, history of smoking, and open gastrectomy were independent risk factors influencing the incidence of surgical site infection. Conclusion Robotic-assisted gastrectomy is a good multimodality treatment option for gastric cancer in terms of reduced length of hospital stay and incidence of surgical site infection.
