Abstract
The current problem of neonatal and pediatric surgery remains the tactics of surgical treatment and postoperative management of patients with perforated peritonitis. Mortality with perforation of the stomach and intestines in children in the newborn period reaches about 40-80 %. The combination of the syndrome of increased intra-abdominal pressure and multiple organ failure causes the extremely serious condition of patients. In this connection, new approaches to the surgical treatment of such patients are currently being actively developed. For this, new medical devices are tested in experimental practice, but the problem of such studies, first of all, lies in the lack of an adequate model of the pathological process. The aim of the work is to analyze the methods of experimental modeling of intestinal perforations described in the public domain. For this, a study was conducted of the most significant scientific publications of such databases as Google Scholar, PubMed, Scopus, eLIBRARY. The present work provides a detailed description of existing options for modeling perforations of various parts of the gastrointestinal tract (stomach, small intestine and colon), depending on the goals of the experiment. Several rather rare techniques based on the introduction of microorganisms are also presented. In addition, the article describes the method proposed by the authors for modeling perforation using laparoscopic access.
