Abstract
Background: Solid pseudopapillary neoplasms (SPNs) of the pancreas are rare neoplasms, and the selection of surgical approaches is still under debate. The aim of this study was to analyze the clinicopathological characteristics and surgical outcomes of SPN patients and to compare the short-term and long-term outcomes between conventional operations and parenchyma-preserving operations. Methods: Patients who underwent pancreatic resection for SPNs between February 2010 and May 2019 in Fujian Medical University Union Hospital were identified. Clinicopathological details, perioperative data, and long-term follow-up results were retrospectively analyzed. Results: Sixty patients underwent surgical resection for SPNs during the study period: 48 females and 12 males. The mean age was 32.2 years. All patients underwent margin-negative surgical resection. The median follow-up period was 47 months (range: 3~118 months). One patient developed liver metastases 14 months after the operation and received local ablation therapy. All patients were alive during the follow-up. The incidence of postoperative pancreatic fistula was higher in the parenchyma-preserving surgery group than in the conventional surgery group (40.0 vs. 11.1%, p = 0.034). There was no significant difference in the tumor recurrence rate between the 2 groups. Eight (17.7%) and 6 patients (13.3%) in the conventional surgery group demonstrated endocrine and exocrine pancreatic insufficiency, respectively; furthermore, no patients in the parenchyma-preserving surgery group had endocrine or exocrine pancreatic insufficiency, but the incidences were not significantly different between the 2 groups. Conclusions: Margin-negative surgical resection of SPNs yields a very low rate of tumor recurrence and excellent long-term survival.Keywords
