[Radiological and instrumental study of the colon in idiopathic constipation]. / Studio radiologico e strumentale del colon nella stipsi idiopatica.

It has been demonstrated that it is not always possible to attribute to constipation a reduced colonic transit time as being evidenced by radiological studies using radiopaque markers. In fact, in constipated patients with a normal transit time, it was more reasonable to consider a recto-anal disorder as evidenced by defecography and manometry.
