The OBJECTIVE was to study the possibilities of endoscopy in the diagnosis and treatment of bleedings in patients with pancreatitis.METHODS AND MATERIALS. Based on the analysis of 135 patients with pancreatitis complicated by gastroduodenal bleeding, we determined the location and possibilities of endoscopic hemostasis. The article analyzes 2 groups of patients. The first group (64 patients with acute pancreatitis and gastroduodenal bleeding). The second group (71 patients with chronic pancreatitis complicated by gastroduodenal bleeding). The article shows features of endoscopic examination of patients with pancreatitis complicated by gastroduodenal bleeding.RESULTS. The leading method of stopping bleeding in these groups of patients is endoscopic hemostasis.CONCLUSION. The choice of endoscopic hemostasis method depends on the cause and nature of the bleeding. The developed technique of endoscopic hemostasis has reduced the mortality rate from gastroduodenal bleeding in patients with pancreatitis to 3 %.
