Пятнадцати неполовозрелым кроликам-­самцам под ингаляционным наркозом производилась лапароскопия, а затем – субсерозное введение повреждающих растворов (33%­го раствора H2O2, 10%­го раствора CaCl2, 4%­го раствора KCl, 70%­го раствора C2H5OH, 10%­го раствора CH2O) в стенку кишки. Через сутки животным выполнялась лапаротомия, визуальная оценка патологических изменений и резекция участка кишечной трубки в области введения повреждающего раствора, после чего накладывался однорядный межкишечный анастомоз по типу «конец-­в-­конец». Из биоптата изготавливались гистологические препараты. Выполнялась морфологическая оценка возникших изменений.</p></sec><sec><title>Результаты</title><p>Результаты: Наиболее выраженные макроскопические и микроскопические изменения обнаружены у животных, которым производили введение перекиси водорода. При оценке изменений в брюшной полости через сутки с момента моделирования отмечалась картина частичной кишечной непроходимости и серозного перитонита. Морфологическая картина характеризовалась явлениями острого расстройства кровообращения в стенке кишки с наличием язвенно-­некротических дефектов и перфоративных отверстий.</p></sec><sec><title>Выводы</title><p>Выводы: С учетом морфологических проявлений разработан способ моделирования осложненного некротического энтероколита из лапароскопического доступа, который легко воспроизводим в эксперименте in vivo, приближен к клинической ситуации, позволяет моделировать типичные морфологические изменения тяжелого течения заболевания.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction: There is no adequate and easily reproducible model of complicated necrotizing enterocolitis (NEC) that allows to study its etiopathogenesis and test various surgical treatment options in an experiment.</p></sec><sec><title>Objective</title><p>Objective: To devise a method for in vivo modeling of complicated NEC using laparoscopy.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: Our study was conducted at the premises of the Laboratory of Experimental Surgery and Oncology (Scientific Research Institute of Experimental Medicine, Kursk State Medical University) in compliance with international ethical standards and guidelines for humane animal treatment. Fifteen immature male rabbits underwent laparoscopy under inhalation anesthesia and then subserosal injection of damaging solutions (33% H2O2, 10% CaCl2, 4% KCl, 70% C2H5OH, 10% CH2O) into the intestinal wall. In 24 hours, we performed laparotomy, assessed pathological changes visually, and resected the section of the intestinal tube at the injection site. Then we performed a single­layer end­to­end intestinal anastomosis. Histological samples were made from a biopsy specimen. Morphological assessment of the changes was performed.</p></sec><sec><title>Results</title><p>Results: The most pronounced macro­ and microscopic changes were found in the animals injected with hydrogen peroxide. We assessed changes in the abdominal cavity 24 hours since the start of modeling and observed a pattern of partial intestinal obstruction and serous peritonitis. The morphological pattern was characterized by acute circulatory disorder in the intestinal wall with ulcerative necrotic defects and perforations.</p></sec><sec><title>Conclusions</title><p>Conclusions: Based on morphological manifestations we devised a method for modeling complicated NEC using laparoscopy. It is easily reproducible in an in vivo experiment, close to the clinical situation, and allows to simulate typical morphological changes during severe NEC.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>моделирование</kwd><kwd>эксперимент</kwd><kwd>животные</kwd><kwd>перфорация</kwd><kwd>некротический энтероколит</kwd><kwd>лапароскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>modeling</kwd><kwd>experiment</kwd><kwd>animals</kwd><kwd>perforation</kwd><kwd>necrotizing enterocolitis</kwd><kwd>laparoscopy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 23-25-10004 в рамках регионального конкурса при поддержке Министерства образования и науки Курской области</funding-statement><funding-statement xml:lang="en">The study was funded by Russian Science Foundation grant No. 23-25-10004 within the framework of a regional competition with the support of the Ministry of Education and Science of the Kursk Region.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Neu J, Modi N, Caplan M.
