Robotic versus open pancreaticoduodenectomy with vascular resection for pancreatic ductal adenocarcinoma: surgical and oncological outcomes from pilot experience.

Purpose: Venous resection and reconstruction (VR) is a feasible surgical technique to achieve optimal outcomes in selected patients with pancreatic ductal adenocarcinoma (PDAC) who undergo open pancreaticoduodenectomy (OPD). However, data regarding patient outcomes in patients who undergo VR in robotic-assisted pancreaticoduodenectomy (RPD) are scarce.
Methods: All patients with a diagnosis of PDAC who underwent upfront open or robotic pancreatoduodenectomy with VR in a high-volume institution for pancreatic surgery between 2011 and 2019 were retrospectively reviewed. Perioperative and long-term outcomes were compared between the RPD and OPD cohorts.
Results: A total of 84 patients were included in the final analysis, 14 patients underwent RPD with VR and 70 who had OPD with VR. Reconstructed venous patency, postoperative 30-day morbidity, and 90-day mortality were comparable; however, lymph node resection rates were lower in the RPC cohort (p = 0.029). No difference was identified in 3-year survival rates between the two groups (34.0% versus 25.7% respectively, p = 0.667).
Conclusion: RPD with VR is a feasible approach for patients with PDAC and venous invasion. Further studies are needed to assess long-term outcomes compared to the open approach.
