BackgroundEnucleation is increasingly used for pancreatic solid pseudopapillary neoplasm (SPN) to preserve function of the pancreas. The data was limited due to rarity of this low-grade neoplasm. We sought to describe the indications, operative technique, short and long-term outcomes after enucleation with largest series of enucleated SPNs.MethodsData collected retrospectively from 110 patients with SPN who underwent pancreatectomy between 2009 and 2016 in our institution were reviewed. Thirty-one patients underwent enucleation were identified for analysis, and compared with the 70 patients underwent conventional pancreatic resection.ResultsOf the 31 patients, 27 (87.1%) were women, and the mean age was 29.8 years (range, 11–49 years). Enucleated SPNs were mostly located in the head/uncinate process of the pancreas (38.7%). Overall morbidity was 25.8%, mainly due to POPF (19.4%), and severe morbidity was only 6.5% with no death. Compared with conventional pancreatic resection, enucleation had a shorter duration of surgery (P < 0.001), less blood loss (P < 0.001), lower rate of exocrine insufficiency (P = 0.033) and comparable morbidity (P = 1), with no increased risk of tumor recurrence (P = 1). The rate of endocrine insufficiency after enucleation seemed lower (Nil vs. 4.5%, P = 0.55).ConclusionsEnucleation of SPN of the pancreas appears to be feasible and safe for preserving exocrine and endocrine function of the gland. Enucleation with negative surgical margin seems adequate with no increased risk of tumor recurrence. Enucleation could be seriously considered as an alternative to conventional resection for this frequently young population.
