This study confirmed the value of both defaecography and colonic transit time in assessing clinically obstructed women. Obstructed defaecation might not always be associated with abnormal colonic transit time. Likewise, not all constipated patients had signs of obstructed defaecation. The differential diagnosis between colonic slow transit constipation and constipation due to pelvic floor disorders is essential for an adequate strategy of care.
The interventional radiology approach yielded results comparable to those reported for the endoscopic method and was always well tolerated. The need to rely on materials mostly designed for endoscopic use can make radiological use difficult in some cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
