Robotic pancreatectomy for solid pseudopapillary tumors in the pancreatic head: A propensity score-matched comparison and analysis from a single center

Abstract

Summary: Background: Robotic surgery is the most advanced minimally invasive technique for the treatment of complicated solid pseudopapillary tumors (SPT). The aim of this study is to evaluate feasibility of robotic surgery for the treatment of SPTs in the pancreatic head. Methods: A retrospective analysis of the clinical data of 83 SPTs in pancreatic head was conducted. Clinical characteristics were extracted and propensity score matching (PSM) was used to compare and evaluate mid-term outcomes of the two techniques. Results: Pancreaticoduodenectomy (PD), duodenum-preserving partial pancreatic head resection (DPPHR-P) and tumor enucleation (En) were performed in 51, 24, and 8 patients, respectively. The robotic approach was associated with a significantly lower volume of blood loss, lower need for transfusion, and faster time to post-surgery recovery. Major complications and costs were comparable for both techniques. Conclusion: A robotic approach provides an alternative to open surgery for SPTs in the pancreatic head without increasing the incidence of clinically relevant pancreatic fistula (CRPF) or other major complications and with good patient outcomes.
