Relevance of research. Acute gastroduodenal bleeding is remaining a difficult and largely unsolved problem up to day. The fundamental importance in treating this category of patients is an endoscopic hemostasis. The decisive point in this problem is the most stable hemostasis and preventing a recurrence of a hemorrhage. In this regard, the search of new solutions and the development of known methods of treatment of the gastroduodenal ulcer bleeding is an important issue.   Aim of research. To evaluate the effectiveness of the treatment protocol of patients with the gastroduodenal ulcer bleeding by applying combined endoscopic insufflations of hemostatic agents and a diovin as an integral part of a complex therapy.   Materials and methods. The research is based on results of treatment of the patients with the gastroduodenal ulcer bleeding being in a medical setting at the departments of surgery at Voronezh city clinical emergency hospital №1. During the treatment of the main group (59 patients) there was used an integrated approach with the usage of powdered hemostatic agents of gelplastan and lyophilisate NovoSeven in combination with diovin in the endoscopic treatment of gastroduodenal ulcer bleeding. There were used the traditional well-known methods of the endoscopic hemostasis without the usage of hemostatic agents and absorbent grains in treatment of the control group (56 patients).   Results and discussion. The evaluation of results of patients’ treatment with gastroduodenal ulcer bleeding was performed according to the figures of the final hemostasis, the frequency of recurrent bleeding, the prevention of emergency operations, the rates of mortality, the duration of hospitalization. The developed protocol of the patients’ treatment with gastroduodenal ulcer bleeding with the usage of combined the endoscopic insufflation of two hemostatics and diovin makes it possible to achieve the maximum persistent hemostasis at 94.9% of patients, to reduce the risk of recurrent hemorrhages by 2.5 times, to prevent emergency operations and, as a result, to reduce the lethality.   Conclusion. The usage  of new technologies of endoscopic hemostasis by the hemostatic pneumoinsufflation  gelplastan and lyophilisate NovoSeven in combination with diovin in the treatment of patients with gastroduodenal ulcer bleeding allows to reduce the risk of recurrent hemorrhage from 12,5% to 5,01% (by 2,5 times), to prevent emergency operations, to reduce the lethality from 3,65% to 1,7% (by 2,1 times) and to reduce the period of staying in the hospital from 10,2 to 7,4 bed days (p<0.05).
