Incidence and risk factors of postoperative complications after robotic gastrectomy for gastric cancer: an analysis of 817 cases based on 10-year experience in a large-scale center

In this study, we investigated the incidence and risk factors for postoperative complications after robotic gastrectomy (RG) in patients with gastric cancer. A total of 817 patients who underwent RG for gastric cancer between March 2010 and August 2019 were analyzed retrospectively. Postoperative complications were categorized according to the Clavien–Dindo classification, and possible risk factors were evaluated. Among 817 patients who underwent RG, overall, severe, local and systemic complication rates were 13.8, 4.2, 7.0 and 6.9%, respectively. Multivariable analysis revealed that an age of 70 years or older (P
