The Types of the Colon Revealed by Hydrocolonic Echography at Chronic Constipation in Children

Abstract

Retrospective cross research of results of a hydrocolonic echography (HCE) in 263 children with a constipations aged from 14 days till 17 years is carried out. The obtained data correlated to clinical manifestations. Seven types of echographic picture of the colon were revealed. The first four types corresponded to clinical forms of a functional constipations: compensated, subcompen-sated (dolihocolon) and decompensation (dolihomegacolon and megarectum), two types reflected features of fixing (Payr´s illness) or function of the colon (spastic colitis), and also type, characteristic for Hirschsprung´s disease. Secondary changes due to constipation are identified: thickening and "lamination" of a wall of a gut, lengthening (additional loops of the colon), dilatation of the lumen, smoothness or absence of the haustra, decrease in activity of a peristalsis, incomplete emptying of the colon, incontinence. Secondary changes didn´t depend on the constipation reason, and were a consequence of violation of depletion of the colon.
