[Surgical treatment of hemorrhaging gastroduodenal ulcer. Individually adapted indications].

Increase in application of emergency gastroscopy together with indications according to "Forrest" criteria, in the course of nine years, resulted in reduction of lethality by 15 per cent among patients who had been surgically treated for bleeding ulcers. Life-threatening postoperative risks were higher without gastroscopy. A critical appraisal is made in this paper of gastroscopic findings, with reference being made to surgical results.
