INTRODUCTION Bleedings after endoscopic removal of gastric polyps continue to be a relevant issue. A technique has been developed for infltrating the base of polyps with a new hemostatic agent Hemoblock to prevent bleedings during polypectomy. The purpose of this study was to assess the effectiveness of this technique.MATERIALS AND METHODS We present the results of the use of Hemoblock in 63 patients with 129 removed polyps. The results were compared with data in the control group, where 267 polyps were removed in 142 patients. In the control group, 0.9% sodium chloride solution, 5% aminocaproic acid solution were used for submucosa injection. We also compared the effectiveness of endoscopic hemostasis for bleeding that occurred after the removal of polyps in both groups. In the main group, hemostasis was performed by irrigation and puncturing using Hemoblock. In the control group the injection method (0.9% sodium chloride solution, 5% aminocaproic acid solution) and electrocoagulation were performed.RESULTS The study showed that the use of Hemoblock during endoscopic removal of polyps for infltration of their base provided a more effective prevention of bleeding, and with the development of bleeding from a thermal defect after polypectomy, the use of irrigation/puncturing of the same drug provides reliable hemostasis.CONCLUSION The use of hemostatic agent Hemoblock in the endoscopic removal of gastric polyps provides prevention of bleeding and radical intervention. With the development of bleeding after polypectomy, irrigation/puncturing hemostatic agent Hemoblock allows to achieve reliable hemostasis.

Local hemostatic agent Haemoblock was used for improvement of the visualization of the source of gastroduodenal bleeding. Intraorgan application of Haemoblock allows endoscopists to identify significant features of biotissue defects and to optimize further actions to achieve reliable hemostasis and to prevent secondary bleeding. Clinical study of the diagnosis and treatment of 84 patients with gastroduodenal bleeding was presented. Preliminary usage of Haemoblock allows to identify the source of bleeding in 98 % cases, to improve intra organ interventions for getting reliable hemostasis and to prevent secondary bleeding in specified localizations.

The problems of surgical treatment of patients with chronic tonsillitis and rehabilitation after surgery using the medication «Hemoblock» are discussed in this paper. The hemoblock was used in the surgical treatment of 165 patients, the control group consisted of 160 patients who underwent standard surgery. The results of the study show that the use of Hemoblock can reduce the number of complications of the operation and reduce the period of hospitalization of patients.
