[Neuroendocrine tumors of the pancreas]

Neuroendocrine tumours are rare and often include insulinoma, gastrinoma and other low frequency tumours that secrete gastrointestinal hormones. Their preoperative localization, despite continuous medical advances, is extremely difficult but helpful in guiding the surgeon towards a proper form of treatment. After presenting their cases, the authors conclude that the treatment of choice for these tumours is surgery due to their anatomopathological features (benign, scarcely malign or invasive, slow growth). On the other hand, medical therapy plays an important role in either preparing the surgical intervention or alleviating symptoms when the patient is inoperable.
