Robotic Duodenum-preserving Total Pancreatic Head Resection for Intraductal Papillary Mucinous Neoplasms.

Robotic duodenum-preserving pancreatic head resection (R-DPPHR) is a technically feasible procedure for benign or borderline tumors of the pancreatic head. Among these, pancreatic cystic neoplasms (PCNs), particularly intraductal papillary mucinous neoplasms (IPMNs), are ideal candidates for this minimally invasive, organ-preserving approach. While numerous studies have demonstrated the short- and long-term advantages of DPPHR over conventional pancreaticoduodenectomy (PD), detailed video descriptions of the robotic-assisted procedure are scarce. This case report presents a step-by-step technical video of R-DPPHRt for a main duct-IPMN (MD-IPMN) in the pancreatic head. A 65-year-old male patient with upper abdominal discomfort was diagnosed with MD-IPMN, presenting as a 4.3 cm cystic-solid mass in the pancreatic head. R-DPPHRt was performed using the da Vinci Xi system, with an operation time of 350 minutes and an estimated blood loss of 150 mL. The patient had an uneventful postoperative course and was discharged on postoperative day 9. Pathology confirmed MD-IPMN with low-grade dysplasia. R-DPPHRt is an effective, function-preserving treatment for selected patients with pancreatic cystic neoplasms, particularly when performed by experienced surgeons in high-volume centers. While this single-case report limits generalizability, the article offers unique value by providing a clear procedural template.
