[Diagnosis and treatment of Zollinger-Ellison syndrome].

An analysis of data concerning 37 patients with the Zollinger-Ellison syndrome (ZES) has been made, 36 of them were operated upon. Gastrinoma was found in 21 patients. Diagnosis of ZES was made in two steps: the first one is fulfilled in general medical institutions, the second one-in specialized clinics. The diagnosis of ZES must be either confirmed or rejected with certainty. When choosing the method of operative treatment several groups of patients must be born in mind: ZES without a gastrinoma detected, ZES with a gastrinoma, ZES with malignant ulcerogenic tumour. The main operation for ZES remains to be gastrectomy.
