| description | When performing surgery, the surgeon should be aware of the direct impact of the suture material on the structure of the sutured tissues and the condition of the postoperative scar, as the right surgical material is the key to rapid and successful wound healing. Therefore, searching for the safest surgical material, especially in pediatric abdominal surgery, is an urgent problem today.
The aim is to determine the morphological changes in the tissues of the cecum over the long term of the experiment using polycaprolactone thread modified with L-arginine.
Materials and methods. Colotomy was performed on 35 sexually mature outbred domestic rabbits (of different sexes) aged 8-10 months and weighing (2.6±0.2) kg. The experimental animals were divided into two groups: control and experimental. The first group was control (5 animals), and the second group was experimental (30 animals), where a monofilament absorbable thread with polycaprolactone modified with L-arginine was used to close the wound defect. The following research methods were used: histological, method of semi-thin serial sections, morphometric, and statistical methods.
Results. Fibroblasts play the most crucial role in the process of reorganization of the postoperative scar among cellular elements. Their activation and increase occur by day 14 of the experiment. On the 30th day of the study, the structural organization and restoration of connective tissue are determined. The reorganization of the muscle component changes: a layer of young myocytes is formed in the gap between the connective tissue capsule around the surgical thread and the fibrous component of the connective tissue fibrillar framework. By the 30th day of the study, the inflammatory reaction involving plasmocytes ceases, and single plasmocytes already perform the function of local immune surveillance. Also, the role of lymphocytes that actively migrate to the focus of the inflammatory process is suppressed by day 30 of the study, and single lymphocytes perform the function of local immune surveillance.
Conclusions. Thus, the dynamic changes in the cellular composition of the tissues of the perivulnar area of the cecum demonstrate the acceleration of the healing process and the formation of a loose scar when using polycaprolactone thread modified with L-arginine.
