RESEARCH • RECHERCHEDiagnosis and surgical treatment of solid pseudopapillary neoplasm of the pancreas: analysis of 24 cases Background: Our aim was to summarize our experience with the diagnosis and surgical treatment of solid pseudopapillary neoplasm (SPN) of the pancreas to provide a reference for the management of this rare condition. Methods:We collected and analyzed retrospective data on the clinical presentation, laboratory investigations, radiologic imaging, pathology and operative details of pa tients with SPN of the pancreas diagnosed between February 2001 and December 2009. Results:In all, 23 of 24 patients were women, and the mean age of all patients was 31 years. The most common clinical presentation was vague abdominal pain. Abdominal imaging showed solid or solid cystic masses in the pancreas, mostly in the tail or head of the gland. All patients were treated surgically. There were no postoperative deaths. After follow-up ranging from 4 to 109 months (median 68 mo), 20 of 22 patients who underwent curative resection were alive with no evidence of disease recurrence. Of the 2 patients with R1 resections, 1 died 42 months after surgery, whereas the other underwent a second operation and was alive after 36 months' follow-up. Conclusion:Solid pseudopapillary neoplasm of the pancreas is a relatively indolent tumour. The initial diagnosis of SPN of the pancreas is suggested by radiologic imaging findings but should be considered in the context of clinical and histopathologic characteristics. We advocate for complete surgical resection once SPN is diagnosed.Contexte : Nous voulions résumer notre expérience du diagnostic et du traitement chirurgical du néoplasme pseudo-papillaire solide (NPS) du pancréas afin d'établir un point de référence pour la prise en charge de ce problème rare.
