The Brooklyn gastrinomas

During the past seven years we have diagnosed and treated 12 patients with the Zollinger-Ellison syndrome (ZES), some of whom have had virtually unique manifestations. Among these are a 74-year-old man who was cured after endoscopic removal of a submucosal duodenal gastrinoma, suggesting the usefulness of an operative approach using intraoperative endoscopic transillumination; a 33-year-old man in whom the manifestations of ZES brought him into conflict with the law; and a 10-year-old domestic cat who was cured surgically, the gastrinoma providing material for the first determination of the sequence of cat gastrins.
