OBJECTIVE: The role of minimally invasive pancreatic surgery for pancreatic neuroendocrine neoplasms (pNENs) in patients with multiple endocrine neoplasia type 1 (MEN1) is not well defined. The aim of this study was to compare the outcome of minimally invasive versus open pancreatic resections in patients with MEN1. MATERIALS AND METHODS: Prospectively collected data of MEN1 patients who underwent a primary distal pancreatic resection and/or enucleation for non-functioning pNENs or insulinoma were retrospectively analyzed regarding the outcome of minimally invasive or open pancreatic resections. RESULTS: Thirty-three patients underwent primary pancreatic resection for either organic hyperinsulinism (n = 9, 27 %) or non-functioning pNENs >1 cm in size (n = 24, 73 %) between 1987 and 2015. 21 (64 %) patients underwent an open surgical (group 1) and 12 patients (36 %) a minimally invasive approach, either laparoscopic (n = 8) or robotic assisted (n = 4) (group 2). Both groups were comparable regarding age, gender, number, and size of pancreatic tumors. In both groups, the hyperinsulinism of all patients (9/9,100 %) could be cured and all NF-pNENs >1 cm could be resected. Group 2 had a significant shorter operative time (200 vs. 260 min; p = 0.036), less intraoperative blood loss (120 vs. 280 ml; p < 0.001), and a shorter hospital stay (11 vs. 15.5 days; p = 0.034). The rate of patients with postoperative complications, especially postoperative pancreatic fistulas, was not different between groups (62 % group 1 vs. 67 % group 2, p = 0.74). CONCLUSION: Minimally invasive distal pancreatic resections and enucleations are feasible and safe in MEN1 patients with insulinoma or non-functioning pNENs.
