Constipation is a common problem in the western world, which occurs as a consequence of impaired colonic transit and/or due to obstructed defecation. Imaging plays an important role in distinguishing structural from functional causes of constipation. In this article a description of common imaging techniques for diagnosing structural causes of constipation with illustrations of abnormal defecographic findings in patients with obstructive defecation are presented.
