Description

<p>Solid pseudopapillary neoplasm (SPN) of the pancreas is a low-grade malignancy that is rare in children. It often occurs in young women, and patients undergoing complete surgical resection show a favorable prognosis. In this study, we investigated treatment outcomes of SPN in our department. We retrospectively reviewed the medical records of six patients with SPN treated in our department between 1990 and 2019. Demographic characteristics, tumor localization, rendered treatment, and outcomes were assessed. All six patients were girls. Their ages at the time of surgery were 6–14 years (median 10.5 years). The tumor localization was the pancreatic body in two patients and the tail in four patients. Four patients underwent distal pancreatectomy with splenectomy and two patients underwent enucleation. Postoperatively, one patient required transfusion because of intraoperative bleeding, and two patients developed grade B postoperative pancreatic fistula (POPF). The postoperative course was uneventful in the other patients. Postoperative hospital stay was 8–28 days (median 14.5 days), and the follow-up period was 1–122 months (median 50.0 months). All six patients were alive without recurrence. Surgical outcomes of SPN were favorable in our case series. Although splenic preservation was difficult in patients with SPN affecting the splenic hilum, laparoscopic mobilization of the spleen was useful during tumor resection in these patients.</p>
