RESUMO
OBJECTIVE: The aim: The study focuses on the morphometric features specification concerning the structural components of the hemomicrocirculatory bed of the perivulnar region of the cecum in rabbits when suturing a wound defect with synthetic polyfilament surgical suture Vicryl. PATIENTS AND METHODS: Materials and methods: The research was carried out on rabbits (n = 30: 5 animals made up the control group and 25 animals made up the experimental group) and included surgery based on the method of surgical intervention on the large intestine patented by the authors, which was performed in the conditions of the operating room at the Department of Clinical Anatomy and Operative Surgery. When determining the main morphometric parameters, we took biopsy specimens of the cecum and used paraffin and epoxy resin embedding considering the generally accepted methods. RESULTS: Results: The study determined that the implantation of Vicryl surgical suture material in the tissues of the cecum became a trigger for the formation of active inflammatory focus and occurrence of leukocyte infiltrate in the perivulnar region. CONCLUSION: Conclusions: Arterioles, as a resistive link, capillaries, as an exchange link and venules, as a capacitive link in the hemomicrocirculatory bed, actively participate in response to the inflammatory process and formation of a connective tissue scar. The process of structural organization of microvessels begins in the formed granulation tissue in the perivulnar region of the cecum starting from the 14th day of the experiment.
