[X-ray diagnosis of the causes of chronic constipation in children].

The genesis of chronic constipation in children remains the subject of discussion so far. A programme for examining patients with this condition has not been fully developed. X-ray studies of more than 300 children with chronic constipation from different age groups established that colonoproctodefecography was the most informative technique. The authors revealed that intestinal transit suffered slightly impaired and the cause of chronic constipation was impaired defecation due to the asynergy of the structures of the pelvic bottom. Dysfunction of the muscular structures of the pelvic diaphragm manifested itself as three main variants and their combinations.
