[Clinicomorphological characteristics of colonic circulatory changes in children with organic and functional colostasis].

Acute colonic perfusion impairments (thrombosis, infarction, and ischemia) have evident clinical manifestations and are reasonably well described in the literature. At the same time, the problems of chronic peripheral circulatory disorder in the large bowel and the impact of the disorder on its motility are inadequately considered. By summarizing the data available in the literature and their findings, the authors consider the etiology and pathogenesis of organic and functional colostasis in the context of changes in the colonic angioarchitectonics.
