The purpose of the study was to investigate hemostasis in children with dys
bacteriosis disturbance in chronic constipation. The disturbance of factors
in the inner mechanism of blood coagulation (VII, IX, XL XII) in compensat
ed chronic constipation was defined based on the reduction in colon bacillu
s levels. We observed hypocoagulation caused by the reduced activity of the
prothrombin complex factors, disaggregate thrombocytopathy, and endothelio
sis with fibrinolysis inhibition in subcompensated chronic colostasis with
continuous reduction of colon bacillus levels and pathogenic microflora app
earance. In decompensated colostasis there was an increase in pathogenic mi
croorganisms and a continuous reduction of colon bacillus levels. In hemost
asis there was a factor deficiency in inner (XII, XI, IX, VIII) and outer (
II, V, VII, X) blood coagulation mechanisms. Fibrinolysis inhibition, endot
heliosis development with thrombocyte aggregation, and microthrombosis form
ation were determined. Thus, in children with chronic constipation, there w
as a marked reduction in the amount of colon bacillus. which led to the rep
roduction of pathogenic bacteria. We also observed chronometric hypocoagula
tion with the inner (XII, XI, IX, VIII) and outer (II, V VII, X) mechanisms
of blood coagulation, at the base of which there is the deficiency of vita
min K-dependent factors (II, VII IX. X) and a slightly marked disturbance i
n the final stage of coagulation. In thrombocyte vascular hemostasis, throm
bocytopathy was observed with increased adenosine-5-diphosphate aggregation
and the inhibition of the inner mechanism with fibrinolysis and endothelio
sis.
