Further studies are needed to investigate the prognosis and perioperative safety of patients undergoing robotic-assisted pancreaticoduodenectomy. In this study, clinical data and prognostic data of patients undergoing this procedure were prospectively collected and analyzed to explore its safety and efficacy.
