448 patients with severe haemorrhage from gastroduodenal ulcera during the last 15 years are presented. Within this period indication, organisation and the choice of method have changed in 3 phases. Included are the endoscopic diagnosis and treatment with very good results. As a result of endoscopy there is a negative selection of patients for surgery causing a depression of the results after surgical treatment. The propagation for early indication even in high risk patients still has validity.
