Topical issues of prevention of acute postmanipulation pancreatitis

Abstract

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most informative and often in-demand methods for the detection and treatment of pathology of the biliary tract, its diagnostic value is 79-98%. A significant disadvantage of the method are side effects and various complications (acute pancreatitis, bleeding, retroduodenal perforation, cholangitis, acute cholecystitis, etc.). Post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) is a common and severe complication of intraluminal endoscopic operations on the large duodenal papilla, its etiology is multifactorial, and the pathophysiology has not yet been fully studied. According to many randomized, controlled studies, the incidence of PEP ranges from 2.7 to 37%. Despite all the possibilities of modern medicine and the introduction of new methods, mortality with the development of PEP remains at a very high level: it reaches 7-15%, and with the development of destructive forms - 40-70%. The problems of prevention of PEP are still the subject of discussions and numerous studies by leading clinics around the world. In this paper, we conducted a review of the literature over the past decade using the sources of major medical libraries Medline, eLibrary, PubMed. The article discusses current modern pathogenetic mechanisms and the main risk factors for the development of PEP, related to both the characteristics of the patient and the procedure being performed, technical options for performing ERCP. The article also presents currently used and recommended by most authors methods of drug prevention of PEP and various technical solutions related to this complication. Thus, the not entirely satisfactory results of the proposed methods of prevention of PEP force the authors to search for safer and more effective solutions to this urgent problem at the present time.
