In 1983, 685 out of 1,284 patients having suffered from a gastroscopically identified gastric ulcer in the period from 1972 to 1980 answered a questionnaire. Males prevailed in a proportion of 1,7:1. They showed an earlier onset of the disease and a higher operational rate. As much as 44.2% of them reported complications (mostly haemorrhage), 44.8% a gastric operation. A review of the operation reports showed an incidence of 1% of gastric carcinoma 1-3 years after gastroscopy. In order to demonstrate a better prognosis of gastric ulcer non-selected prospective long-term studies should be performed.
