Milan, Italy ABSTRACT Context Atypical resections of the pancreas (ARs), including enucleation (E) and middle pancreatectomy (MP), are parenchyma-sparing techniques aimed to reduce the risk of postoperative pancreatic insufficiency. While ARs are safely performed for treating insulinomas, their role in the management of non-functioning pancreatic endocrine tumors (NF-PETs) is debated. Aim To evaluate perioperative and long-term outcomes of 127 patients (53 male, 74 female, median age 46 years) who underwent AR for insulinomas and NF-PETs at two academic, tertiary centers for pancreatic surgery. Methods The outcomes after AR for NF-PETs (n=52) were compared with those of patients who underwent AR for insulinomas (n=75). Results Overall, 91 enucleations and 36 MPs were performed. Enucleation was carried out in 63 patients with insulinomas (84%) and in 28 patients (54%) with NF-PETs
