Endocrine Tumors of the Pancreas

Abstract

A review of 33 patients operated on between 1951 and 1978 for endocrine tumors of the pancreas is presented. The series consists of 25 patients with hyperinsulinism, 6 with the Zollinger-Ellison syndrome, and 2 with the WDHA syndrome. Clinical features and diagnostic problems are discussed. A noticeable feature is that the average time lapse between onset of symptoms and final diagnosis in insulinoma patients has not been significantly reduced during the years covered by this review. This is in spite of the progress made in testing procedures and laboratory methods designed to diagnose hyperinsulinism. Resection of the tumor has been the preferred treatment in insulinoma patients, of whom 22 are still alive. Insulinomas were associated with other endocrinopathies in 3 cases. Patients with the Zollinger–Ellison syndrome had raised serum gastrin levels and increased basal acid output. Four patients are still alive. Two patients had other endocrinopathies. Both patients with the WDHA syndrome died shortly after the operation. One had biochemical evidence of multiple endocrinopathies.
