Были выделены 2 группы животных: первая – 12 особей и вторая группа 11 особей. Для создания малотравматичной модели грыжи использовали эндоскопическую стойку производства Эндомедиум (Казань, Россия), оптический троакар VISIPORT (USA) 5–12 mm AutoSuture с лапароскопом. Для тестирования биологического имплантата выбрана аутокожа (патент РФ на изобретение № 2022103233 от 09.02.2022). Также проведено тестирование аппаратного устройства (вытяжного механизма) (патент РФ на изобретение № 2022131316 от 28.07.2023).</p></sec><sec><title>Результаты</title><p>Результаты. Через 30 дней в обеих группах диастаз соответствовал грыже W3. В первой группе (основная – 12 особей) он составил в среднем 13,14 ± 1,33 см (М ± m). Площадь грыжевых ворот колебалась в обеих группах от 291,55 ± 37,35 до 666,6666 см2. Во второй группе (11 особей) диастаз соответствовал в среднем 12,8 ± 1,29 см (М ± m) при площади 274,02 ± 38,55 см (М ± m). Летальности в обеих группах не зарегистрировано. При анализе результатов в течение первой недели у одного животного из первой группы произошла полная эвентрация в нижнем углу раны, которая была ушита. У трех животных отмечено нагноение раны со вскрытием гнойников. В течение второй недели у одного животного второй группы зафиксировано локальное нагноение около прорезавшей лигатуры, у трех особей, у которых вскрывали гнойник, определялись инфильтраты в проекции послеоперационного рубца. В течение третьей и четвертой недели у этих трех животных фиксировали наличие инфильтрата в проекции послеоперационного рубца. На втором этапе эксперимента перед грыжесечением после выкраивания кожного лоскута у этих трех животных были обнаружены хронические абсцессы. В первой группе осложнений не было.</p></sec><sec><title>Заключение</title><p>Заключение. Созданная хроническая модель грыжи малоинвазивным методом имеет все элементы послеоперационной грыжи W3, имеет меньшие послеоперационные осложнения в зоне ее формирования что способствует более благоприятному условию для тестирования имплантатов и хирургической техники.</p></sec></abstract><trans-abstract xml:lang="en"><p>The purity of testing of implants and medical equipment depends on the creation of an experimental model.</p><sec><title>The purpose of the study</title><p>The purpose of the study: to create a chronic model of a median hernia for testing various implants or surgical techniques.</p></sec><sec><title>Material and methods</title><p>Material and methods. 23 female pigs weighing 15-20 kg underwent surgery to induce a postoperative hernia model. 2 groups were identified. To create a low-traumatic hernia model, an endoscopic stand manufactured by Kazan, an optical trocar VISIPORT 5-12 mm AutoSuture with a laparoscope were used. To test the biological implant, an autocutaneous skin was chosen (Russian patent for the invention No. 2022103233 / 09.02.2022). A hardware device (exhaust mechanism) was also tested (Russian patent for the invention No. 2022131316 / 28.07.2023).</p></sec><sec><title>Results</title><p>Results. After 30 days in both groups, diastasis corresponded to hernia W3. In the first group (main 12 individuals), it averaged 13.14 ± 1.33 cm (M ± m). The hernia gate area ranged in both groups from 296.53 ± 43.32 to 666.6666 square centimeters. In the second group (11 individuals), diastasis corresponded to an average of 14.34 ± 1.33 cm (M ± m) with an area of 296.53 ± 43.32. There was no mortality in both groups. When analyzing the results during the first week, the 1st animal had a complete eventration in the lower corner of the wound, which was sutured. In three animals, suppuration of the wound with the opening of the abscesses. During the second week, one animal of the second group had local suppuration near the cutting ligature, and in three animals in which abscesses were opened, infiltrates were detected in the projection of the postoperative scar. During the third and fourth week, the presence of infiltrate in the projection of postoperative was recorded in these three animals. At the second stage of the experiment, chronic abscesses were found in these three animals before herniation after cutting out the skin flap. There were no complications in the first group.</p></sec><sec><title>Conclusion</title><p>Conclusion. The created chronic model of a minimally invasive hernia has all the elements of a W3 postoperative hernia, has fewer postoperative complications in the area of its formation, which contributes to a more favorable condition for testing implants and surgical techniques.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>послеоперационная вентральная грыжа</kwd><kwd>моделирование грыжи</kwd><kwd>тестирование имплантата и медицинской техники</kwd></kwd-group><kwd-group xml:lang="en"><kwd>postoperative ventral hernia</kwd><kwd>hernia modeling</kwd><kwd>implant and medical equipment testing</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы декларируют отсутствие внешнего финансирования для проведения исследования и публикации статьи</funding-statement><funding-statement xml:lang="en">The authors declare that there is no external funding for the exploration and analysis work</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">de VriesReilingh T.
