This article presents a morphological study of resected colon preparations with sub- and decompensated forms of chronic colostasis. Intestinal morphological examination was carried out in 26 sick children operated on in the period 2018-2019. the subcompensated form of the disease in 7 (27.0%) and decompensated in 19 (73.0%) patients.
It was revealed that the leading pathological changes are structural changes in the vascular bed, especially microcirculation. An important change in microvessels is the appearance in them of a large number of microthrombi. The revealed changes determine the ineffectiveness of conservative therapy for decompensated forms of chronic constipation and can serve as one of the arguments in favor of choosing a surgical method of treatment.
