Abstract
Our simple method of defecography has proved to be more sensitive than clinical evaluation in the detection and description of defecation disorders. Among the different types of disorders, described on the basis of 144 abnormal defecograms, the most common are rectal intussusception (RI), intraanal rectal intussusception (IRI), external manually (EMRP) or spontaneously (ESRP) reducible prolapses, rectocele, and accentuation of the impression of the puborectalis sling (AIPR).
Study of the mean values of the anorectal angle (ARA) (normal mean value=92° at rest) reveals an increase (p<0.05) in the ARA in IRI and ESRP and a decrease (p<0.05 at rest,p<0.001 at strain) in AIPR. The most striking observation is a highly significant increase (p<0.001) in the ARA associated with incontinence.
