[Clinical examination in dyschesia].

Dyschesia, also called obstructed defecation syndrome (ODS), is a difficulty to exonerate with straining. A rectocele or an intussusception are the main causes. Defecation is facilitated by digital maneuvers into vagina in case of rectocele or on the perineum in intussusception. Clinical examination is conducted at rest and at strain allowing exposing the rectocele. Vaginal valves may allow differentiating an anterior colpocele to a rectocele. An anterior rectal hernia should be accentuated by digital examination of the rectum. Clinical examination in intussusception is poor. An ODS scoring is useful to determine the severity of the symptoms and to appreciate the therapeutic results comparing pre- and post-treatment scores.
