title: [Insular tumours of the pancreas (author's transl)].
abstract: The use of immunohistochemistry and radioimmunological assay of the pancreatic polypeptides in the plasma has contributed substantial advances to the histophysiopathology and preoperative diagnosis of tumours of the endocrine pancreas and the related functional syndromes. Consequently, in addition to furthering knowledge on clinical pictures already known for some time, it has been possible to define new categories of the disease which were previously misunderstood or confused with others. The physiopathology and diagnostic methodology (clinical, biohumoral and instrumental) of each main known syndrome (insulinoma, Zollinger-Ellison Syndrome, Verner-Morrison disease and glucagonoma) are described in detail; there are notes on hormonal syndromes that are not fully known and which constitute a field of research in evolution (pluriendocrine and carcinoid syndromes, polypeptidoma, somatostatinoma, nesidioblastosis). The problems of preoperative preparation, intraoperative diagnostic tactics and surgical technique are illustrated. Lastly the possibilities of alternative therapeutic treatment are outlined.
