In our retrospective study we evaluate a success of endoscopic therapy of nonvariceal bleeding in upper part of gastrointestinal tract. We aim at causes of its failure, necessity of subsequent surgical intervention and its success. Success of haemostasis of bleeding in upper part of gastrointestinal tract is more than 98 % in our department. It correlates well with other published studies in the world. The most usual cause of endoscopic failure was an ulcer with bleeding vessel, Forrest IA in 30 cases. Patient’s mortality with failed endoscopic treatment was high (17 %) despite the surgical treatment. It depends on the one hand on cause of bleeding, on the other hand on complicated patient’s comorbiditi’s.
