Modern management of acute non-variceal upper gastrointestinal bleeding

Abstract

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.
