Management of patients with neuroendocrine tumors (NETs) of the pancreas causes considerable controversy because rarity of this neoplasm.The aim of the study was to present our results of treatment of patients with NETs and to sum up our experience in surgical management.Material and methods. Thirty four patients with neuroendocrine tumors of the pancreas were treated in Department of General, Endocrine and Transplant Surgery of Medical University in Gdańsk (24 inulinomas and 10 nonfunctioning neuroendocrine tumors). Insulinoma was present in the head of the pancreas in 3 cases, in the body in 8 cases, and 10 patients had lesion situated within the tail.Results. Localization of the tumor in patients with organic hyperinsulinism was possible in 21 out of 24 operated patients (17 patients with use of preoperative imaging studies, 4 patients with Intraoperative ultrasonography). In 3 remaining patients the localization of the pathologic mass was impossible with use of pre- and intraoperative techniques.Conclusions. Treatment of choice of patients with neuroendocrine tumors of the pancreas is surgery. Management of patients with islet cells adenomatosis is still difficult clinical problem.
