Background: Solid pseudopapillary tumors (SPTs) are rare, benign tumors of the pancreas that present as heterogeneous masses. We sought to evaluate the short- and long-term outcomes of surgical resected SPTs. Patients managed via initial surveillance were compared to those who underwent upfront resection.Methods: A prospectively maintained institutional database was used to identify patients who underwent surgical resection for a SPT between 1988 and 2018. Data on clinicopathological features and outcomes were collected and analyzed.Results: Seventy-eight patients underwent surgical resection for SPT during the study period. The mean age was 34.0 ± 14.6 years and a majority were female (N = 67, 85.9%) and white (N = 46, 58.9%). Thirty patients (37.9%) were diagnosed incidentally. Imaging-based presumed diagnosis was SPT in 49 patients (62.8%). A majority were located in the body or tail of the pancreas (N = 47, 60.3%), and 48 patients (61.5%) underwent a distal pancreatectomy. The median tumor size was 4.0 cm (IQR, 3.0-6.0), nodal disease was present in three patients (3.9%), and R0 resection was performed in all patients. No difference was observed in clinicopathological features and outcomes between patients who were initially managed via surveillance and those who underwent upfront resection. None of the patients under surveillance had nodal disease or metastasis at the time of resection; however, one of them developed recurrence of disease 95.1 months after resection. At a median follow-up of 36.1 months (IQR, 8.1-62.1), 77 (%) patients were alive and one patient (1.3%) had a recurrence of disease at 95.1 months after resection and subsequently died due to disease.Conclusions: SPTs are rare pancreatic tumors that are diagnosed most frequently in young females. While a majority are benign and have an indolent course, malignant behavior has been observed. Surgical resection can result in exceptional outcomes. [ABSTRACT FROM AUTHOR]

Introduction: Robotic pancreaticoduodenectomy is slowly gaining acceptance within pancreatic surgery. Advantages have been demonstrated for robotic surgery in other fields, but robust data for pancreaticoduodenectomy is limited. The aim of this study was to compare the short-term outcomes of robotic pancreaticoduodenectomy (RPD) to open pancreaticoduodenectomy (OPD) and laparoscopic pancreaticoduodenectomy (LPD). Methods: Patients who underwent a pancreaticoduodenectomy between January 2011 and July 2019 at the Johns Hopkins Hospital were included in this retrospective propensity-matched analysis. The RPD cohort was matched to patients who underwent OPD in a 1:2 fashion and LPD in a 1:1 fashion. Short-term outcomes were analyzed for all three cohorts. Results: In total, 1644 patients were included, of which 96 (5.8%) underwent RPD, 131 (8.0%) LPD, and 1417 (86.2%) OPD. RPD was associated with a decreased incidence of delayed gastric emptying (9.4%) compared to OPD (23.5%; P = 0.006). The median estimated blood loss was significantly less in the RPD cohort (RPD vs OPD, 150 vs 487 mL; P < 0.001, RPD vs LPD, 125 vs 300 mL; P < 0.001). Compared to OPD, the robotic approach was associated with a shorter median length of stay (median 8 vs 9 days; P = 0.014) and a decrease in wound complications (4.2% vs 16.7%; P = 0.002). The incidence of other postoperative complications was comparable between RPD and OPD, and RPD and LPD. Conclusion: In the hands of experienced surgeons, RPD may have a modest yet statistically significant reduction in estimated blood loss, postoperative length of stay, wound complications, and delayed gastric emptying comparing to OPD in similar patients.
