The incidence of splenic injuries among all closed injuries of the abdominal cavity is from 15.5 to 30.0 %, and a mortality rate is between 7 % and 26 %. The tactics in the treatment of splenic injuries is determined by the degree of traumatic injury, the patient's condition during the operation, and a concomitant pathology. Studies of tissue regeneration of the operated spleen allow identifying two main options for its regeneration, associated with the nature of blood circulation in the preserved part.
Objective — to study the regeneration and filtration function of the spleen after various types of surgery for the management of traumatic spleen injuries.
Materials and methods. The results of treatment of 85 patients in the period 2015 — 2020 were analyzed. To investigate the changes in the filtration function of the spleen, a study of the peripheral blood (general blood test) was performed to assess the shape of erythrocytes. In order to determine the size of the residual splenic parenchyma, its structure and regenerative processes were evaluated and sonographic examination was carried out.
Results. The average increase in the size of the residual splenic tissue after subtotal resection of the organ with the formation of couplings of the parenchyma averages 40.2 ± 3.4 % one year after surgery, and in patients who underwent subtotal resection of the spleen with covering the cut plane with adhesive hemostatic plate 70 % — 49.14 ± 6.77 %. The study of changes in the filtration function of the spleen in patients, who underwent subtotal resection of the spleen, showed the appearance of target cells, acanthocytes and halocytes in the peripheral blood, but their number was insignificant and did not exceed normal (not more than 3 %). Any destroyed and pathologically altered erythrocytes were not visualized in patients, who underwent atypical resection of the spleen (mass deficit less than 30 %).
Conclusions. Spleen regeneration is determined both by the nature of blood supply to the residual splenic tissue and its size, and does not depend on the nature of the pathological process. Organ‑preserving surgical interventions on the spleen allow maintaining the filtration function of the spleen.
