[The value of endoscopy in acute hemorrhage of the upper gastro intestinal tract].

1808 esophage-gastro-bulboscopies were performed, in 156 cases (8.0%) because of acute haemorrhage, from 1975 to 1979. In 14 cases (9.0%) no lesion could be detected. In 3 patients (1.9%) an exact localization of the bleeding lesion could not be attained. Gastric and duodenal ulcerations were (57.1%) the most frequent causes of haemorrhage, followed by erosive lesions (12.8%). Multiple bleeding sources were realized in 24 patients (15.4%). At present endoscopy is the initial method for diagnosing the causes of acute bleeding in the upper digestive tract.
