[The pathogenesis of the Zollinger-Ellison syndrome]

Abstract

The paper discusses data on 48 cases of Zollinger-Ellison's syndrome. Surgery was performed in 45 patients and ulcerated tumor (UT) found in 32. Tumor was detected in the pancreas (17 cases), duodenum, stomach, liver and parapancreatic fat tissue. Multiple tumors were detected in 3 patients. Twenty-seven percent of UT were genuinely or suspiciously malignant. A histological and clinical classification of gastrin-secreting neoplasms is presented. Surgical treatment for Zollinger-Ellison's syndrome presenting with UT and the results of surgery are discussed.
