The comparative morphological characteristic of the structure of scarring tissue of the surgical wound closed with the prolonged flow aspiration drainage of subcutaneous tissue
Aim. To give the morphological characteristic of scarring tissue of the surgical wound closed with the prolonged flow aspiration drainage (PFAD) of subcutaneous tissue and without it. Material and methods. The study involved 40 outbred rabbits (20 in the main group, 20 in the control one). Histomorphological evaluation of tissue blocks of surgical wounds of the anterior abdominal wall, taken on the 15th, 20th, 25th and 30th post-surgery days, was carried out. Results. Formation of granulation tissue and scarring of wounds of the animals in the main group, to which PFAD of subcutaneous tissue was applied, occurred alongside less destructive inflammations. The free space, on the place of a removed flowing drainage of the surgical wound, was gradually filled with granulation tissue, and then with the cicatricial one; and by 25 - 30 days after surgery it merged with the total cicatricial mass, without leaving any free cavities. Conclusion. PFAD of subcutaneous tissue of surgical wounds promotes favorable regeneration and less complicated post-surgery period in comparison with the surgical wounds closed in the traditional layer-by-layer tight way.
