title: Defecatory disorders, anorectal and pelvic floor dysfunction: a polygamy? Radiologic and manometric studies in 41 patients.
abstract: A consecutive series of 41 patients with defecatory disorders was prospectively studied by anal manometry and evacuation proctography to determine the relationship between abnormalities and symptoms. The patients (29 female, 12 male, aged 41 +/- 2.3 years) all complained of difficulty in evacuation. All had normal colonoscopy and biochemistry. There was no evidence of megacolon or megarectum, and no symptoms had been previously treated by pelvic floor surgery. All subjects completed detailed questionnaires related to gastrointestinal symptoms with special reference to excessive straining and discomfort, digital manipulations during defecation, a sense of pelvic heaviness and incomplete evacuation. Each patient underwent clinical examination, anal manometry and defecography during a single outpatient visit. Rectocele (16 patients) was significantly associated with vaginal digitation, lower stool frequency, delayed rectal emptying and decreased rectal sensation to distension. Increased anal pressure on straining (14 patients) was also related to a poor rectal emptying in 13 patients. Neither perineal descent (24 patients) nor external rectal prolapse (12 patients) was related to objective obstruction. Nevertheless there was an association with pelvic heaviness and lower anal manometric recordings. Five among 16 patients with rectocele had manometric anismus. Forty percent of patients with intussusception also had a paradoxical sphincter response during defaecation. Furthermore, associated abnormalities were extremely common (34 of 41 patients), accurate interpretation of which was necessary for planning effective therapy.
