Background: The aim of this analysis is to compare the postoperative outcomes of resection and enucleation of small pancreatic neuroendocrine tumors (PNETs).
Methods: The 2014-17 American College of Surgeons-NSQIP dataset was queried. Patients undergoing pancreatoduodenectomy (N = 297) or distal pancreatectomy (N = 712) for nonfunctional, small PNETs (T1/T2) were compared to 127 patients (11%) who were enucleated.
Results: Operative time (170 vs 261, p < 0.01) and transfusions were less in the enucleation cohort (1.6% vs 6.7% p < 0.01). There was no difference in postoperative pancreatic fistulas, but morbidity was lower in enucleated patients (36.2% vs 48.7% p < 0.01). Fifteen resected patients died postoperatively (1.5%) while all enucleated patients survived (p = 0.058). Mean postoperative length of stay was shorter after enucleation (5.7 vs 7.2 days p < 0.01).
Conclusions: Enucleation of PNETs is performed in only 11% of patients, but takes less time, requires fewer transfusions, and is associated with reduced morbidity and shorter length of stay than resection.
