What does this research mean for the field?

Postoperative pancreatic fistula occurs in half of patients undergoing resection for pancreatic neuroendocrine tumors, with risk influenced by tumor location, functionality, and absence of metastases, and its occurrence is associated with lower long-term mortality reflecting favorable localized disease biology. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Evaluate the incidence, predictors, and clinical impact of postoperative pancreatic fistula (POPF) in patients with pNETs.

Evaluate the incidence, predictors, and clinical impact of postoperative pancreatic fistula (POPF) in patients with pNETs.
Retrospective analysis of patients who underwent resection for histologically confirmed pNETs from 2010-2019 at a tertiary center.
Assessment of clinicopathological parameters and surgical procedures for association with POPF occurrence and severity.
Statistical analyses performed included χ², Fisher’s exact, Spearman correlation tests, and multivariable regression analysis.
53 patients (50%) developed a POPF; 60% were Grade B, 34% Grade A, and 6% Grade C.
Higher POPF risk associated with distal pancreatectomy for tail lesions (60%) and functional pNETs (77%).
Long-term mortality was lower in patients with POPF (8% vs. 29%).
