[Possibility of radiology in the study of defection disorders].

Chronic constipation and defecation disorders are a very common disease, but the diagnosis is often unsatisfactory and therefore therapy is mostly inadequate. The purpose of this paper is to demonstrate the contribution of radiological procedures and mainly of the defecography, in improving and determining the diagnosis itself. Many normal and pathological cases are reviewed, described and demonstrated by radiological patterns. Finally, a correct protocol of different procedures, radiological and not, for morphological and functional study of large bowel and pelvis floor is stressed.
