Objective: the objective of the present study was to analyze the characteristics of resected incidental lesions of the pancreas.
Material and methods: a retrospective study was performed of pancreatectomies due to incidentalomas between 1995 and 2018.
Results: one hundred pancreatectomies were performed due to incidental lesions; 64 (64%) were solid and 36 (36%) were cystic lesions. The cytological analysis agreed with the diagnosis in 67/71 (88.7%) cases. Thirty-six tumors were cystic, 48 were neuroendocrine and 16 were adenocarcinomas. Disease-free survival for patients with cystic, neuroendocrine tumors and adenocarcinomas was 100%, 79% and 57.7% (p < 0.04).
Conclusion: pancreatic incidentalomas have a heterogeneous phenotype and should be treated in experienced centers.
