BACKGROUND: Robotic pancreatectomy is gaining momentum; however, limited data exist on the long-term survival of this approach for pancreatic ductal adenocarcinoma (PDAC). The objective of this study is to compare the long-term oncologic outcomes of robotic pancreaticoduodenectomy (RPD) and robotic distal pancreatectomy (RDP) to open surgery in patients with PDAC. STUDY DESIGN: Robotic and open pancreatectomy for stages I-III PDAC were obtained from the 2010 to 2016 National Cancer Database. RESULTS: We identified 17 831 pancreaticoduodenectomies and 2718 distal pancreatectomies of which 626 (4%) and 332 (12%) were robotic, respectively. There was no difference in median overall survival between RPD (22.0 months) and open pancreatoduodenectomy (21.8 months; logrank P = .755). The adjusted hazard ratio [HR] was 1.014 (95% confidence interval [CI]: 0.903-1.139). The median overall survival for RDP (35.3 months) was higher than open distal pancreatectomy (ODP) (24.9 months; logrank P = .001). The adjusted HR suggests a benefit to RDP compared to ODP (HR, 0.744; 95% CI: 0.632-0.868) CONCLUSION: In a national cohort of resected pancreatic adenocarcinoma, the robotic platform was associated with similar long-term survival for pancreaticoduodenectomy, but improved survival for distal pancreatectomy.
