Uncontrollable products of gastrin, hyper stimulation and hyperplasia of covering cells of a stomach, increase in products of hydrochloric acid


<1% of patients with round ulcers; frequency of new cases — 0,5 on 1 million. In a year

Main clinical manifestations

1. Recurrent round ulcers, refractory to usual therapy, are more often in a duodenum bulb

2. Diarrhea and steatorrhea (50% of cases)

3. Metastasises of a malignant gastrinoma in a liver and other bodies (60%)


1. The gastrin level increased at least by 3 times

2. Increase of basal level of secretion of hydrochloric acid at an intact stomach more than 15 mmol/h, and at resected more than 5 mmol/h

3. Topical diagnosis of a tumor

Differential diagnosis

Peptic ulcer


Tumor resection; at not operability — anti-proliferative (oktreotid) and symptomatic (omeprazol) therapy
