[Constipation and incontinence: significance of colonic transit time, anorectal manometry and defecography].

Constipation and fecal incontinence are frequent motives of gastroenterological consultation. An etiological diagnosis can often be suspected from the history and can be confirmed by functional testing. We here report our experience with the measurement of colonic transit time (TTC), anorectal manometry (MAR) and defecography (D). Whilst TTC was unhelpful, MAR revealed abdomino-pelvic asynchrony (anismus) in 60 constipated patients and 7 (47%) of 15 incontinent patients. Perineal descent was suspected in 25 constipated patients and confirmed by defecography, which also revealed associated static pelvic disorders. Our experience confirms the role of functional exploration in the investigation of constipation and fecal incontinence and permits a more precise therapeutic approach.
