Prediction and prevention of postoperative intra-abdominal adhesive complications in children

The aim of this work was to study the morphology of adhesion formation under the influence of ozone in the experiment, as well as the development of prediction criteria and methods for correcting increased adhesion in children.

Materials and methods. Experimental studies were carried out on 36 rabbits «Shinshilla» with a body weight of 0.7–1.2 kg., of which 12 animals were included in the control group, which did not carry out ozonation of the abdominal cavity. The main group consisted of 24 rabbits, which were divided into two subgroups (12 animals in each subgroup), which ozonized the abdominal cavity with an ozone-oxygen mixture. In order to study the prognostic value of the acetylation phenotype in the formation of intraperitoneal adhesions, 67 children with symptoms of adhesive intestinal obstruction were examined.

Results. The results of experimental studies showed that in animals of the control group there was the formation of massive adhesions. The basis of adhesions is connective tissue with a significant number of fibroblasts, blood vessels and collagen fibers. In animals of the main group, sharp inhibition of adhesion formation, a delay in the differentiation of fibroblasts and inhibition of their synthetic function were revealed. Acetylation phenotype was determined in 58 patients with appendicular peritonitis. 30 (51%) children turned out to be slow acetylators, and in 28 (49%) patients the phenotype of fast acetylation was established. The results of the study allowed us to isolate fast acetylators as a risk group for excessive adhesion formation and timely start therapeutic and preventive measures.
