[ENDOSCOPIC INJECTION TREATMENT OF BLEEDING PEPTIC ULCER].

BACKGROUND: Objectives were two. (1) to determine theefficiency of the endoscopic injection therapy (EIT) in patients suffering from bleeding caused by peptic ulcer disease with high risk of recurrence, and (2) to recognize clinical and endoscopical risk factors that influence recurrence of hemorrhage and mortality from this pathology. METHODS: This is a retrospective study that included 121 patients, who were admitted by a unit specialized in managing gastrointestinal hemorrhage owing to peptic ulcer with active bleeding or non-bleeding visible vessel, and who underwent EIT with epinephrine between March, 1994 and February, 1996.
