Acute, non-varicose bleeding from the upper gastrointestinal tract remains a common clinical problem. Bleeding episodes are associated with high mortality and a significant economic burden on the health care system. Despite the continuing improvement in endoscopic treatment, recurrent bleeding and associated mortality are still a pressing issue. In addition to the well-established modalities of endoscopic hemostasis: injection, thermal, mechanical, used both as mono therapy and as part of a combination therapy, the review discusses the use of novel types of endoscopic devices. The results of the use of over-the-scope clips, coagrasper, hemostatic sprays, endoscopic angiography, radiofrequency ablation, cryotherapy and endoscopic suturing device are described. The technical aspects of their application, the issues of efficacy and safety, the advantages and limitations of methods for achieving final endoscopic hemostasis are considered. The methods of initial assessment and treatment strategies for recurrent bleeding and unsuccessful endoscopic hemostasis were also analyzed. Material and methods. Literature search was carried out using the following electronic information resources: CyberLeninka, PubMed, Nature Pathology, MEDLINE, PLoS ONE. Results. Сombined endoscopic hemostasis is a standard therapy in the treatment of gastrointestinal tract cerebral infections with an efficiency of 95-98 %, new modalities of endoscopic hemostasis are able, in some cases, to achieve final endoscopic hemostasis both in primary endoscopic treatment and in recurrent bleeding.
Esophagogastroduodenoscopy (EGDS) is the main way to diagnose bleeding from the upper gastrointestinal tract. Diagnostic accuracy of the study depends on the preparation. Aim of the study was to evaluate the preparation of the upper parts of the digestive tract in case of esophagogastroduodenal bleeding. Material and methods. The retrospective analysis of 2570 case histories was carried out. Gastric lavage through nasogastric tube was carried out in the main group (1299 patients). Preparation for the primary EGDS was not carried out in the control group (1271 patients). A comparison of the number of EGDS performed and the detection of the bleeding source in the control and the main groups as well as the period of investigation up to the detection of the bleeding source were performed. Results. EGDS without preparation of the upper gastrointestinal tract in case of acute bleeding and determination of the diagnosis is possible in 85,6 % of patients. Preparation of the upper gastrointestinal tract for EGDS prolongs the study period by 30–60 minutes, but allows establishing the diagnosis in 93.7 % of cases that is by 8.1 % more than without preparation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
