Diagnosis of disturbances of continence and defecation.

Defecography was performed in 60 patients with disorders of continence or defecation in whom previous investigative procedures had not revealed any abnormality that could explain the disorder. A correct diagnosis was made in 47 patients (78%). Defecography appears to be a suitable procedure to detect functional disturbances of defecation. Since anterior rectal wall abnormalities such as colitis cystica profunda and solitary rectal ulcer were seen in eight patients, it is suggested that these abnormalities are a result of functional disorders of defecation. Furthermore, the function of the pelvic floor musculature can be assessed by defecography in order to determine the cause of fecal incontinence.
