Description
Zollinger–Ellison syndrome (ZES) is a rare pathology that does not have specific clinical manifestations and is not always diagnosed in time. This is attributed to doctors’ insufficient awareness of this pathology and the limited availability of the necessary examination methods. Foreign literary sources on this problem are analysed. Historical data regarding the discovery of this pathology and the origin of the syndrome’s name are provided. The epidemiology of the disease is highlighted. The most characteristic clinical manifestations and possible complications of ZES are described in detail. The characteristic changes in gastric acid production associated with this pathology and their diagnostic value (sensitivity and specificity) are presented. At the same time, indicators of both basal and maximal stimulated gastric acid production are significantly increased. The most important stage in the examination of patients with suspected ZES is the determination of blood gastrin levels. At the same time, it is shown that it is not always possible to make definitive judgements in support of ZES based on gastrin indicators. An absolute criterion in favor of ZES is fasting gastrin values of 1000 pg/ml or more. When gastrin levels are less than this indicator, tests using secretin or calcium gluconate have significant diagnostic value. In these circumstances, tests with secretin or calcium gluconate are mandatory. The information on the possible localization of gastrin, the incidence of malignant transformation, and the mechanism of metastasis is given. Methods of determining gastrin localization, sensitivity, and specificity are described in detail. Based on the findings, a differentiated treatment strategy for patients with ZES is provided. Indications and contraindications for surgical and medical treatment of patients with ZES are given. The prospects of a new treatment direction - the use of targeted radiotherapy - are shown. These patients require constant monitoring by a gastroenterologist and a surgeon and periodically undergo the necessary examinations.
