Abstract

The search for methods of reliable hemostasis after surgical interventions on the spleen is an urgent problem of veterinary surgery. Due to the peculiarities of the structure of the vascular bed and organ hemodynamics, prolonged and profuse bleeding, life-threatening, occurs when the spleen is damaged.
We conducted an experimental morphological study aimed at evaluating the comparative effectiveness of laser resection and electrocoagulation to ensure hemostasis after partial resection of the spleen. The work was carried out on rabbits (14 animals). It is shown that after laser resection, a thick scab forms on the surface of the wound of the spleen, and thrombosis occurs in the underlying tissues. Hemorrhages are observed in the underlying layers of the organ. All this indicates reliable hemostasis. After resection with an electrocoagulator, the scab is thinner, bullae are located in it. In the tissues under the scab, blood clots and hemorrhages are visible, which spread under the capsule and in some cases to the surface of the wound through the scab layer. This indicates the possibility of resumption of bleeding after coagulation. On the 7th day after surgery, both groups showed signs of encapsulation and organization of the necrosis zone, as well as its channeling by blood vessels with migration of lymphoid tissue cells, which indicates regeneration. The data obtained allow us to conclude that the use of a laser for resection of the spleen is accompanied by more reliable hemostasis compared to electrocoagulation, which further creates conditions for organ repair.
