BACKGROUND: Constipation is a collective term for symptoms of different aetiologies and pathophysiologies. Our aim was to determine the prevalence of colorectal pathophysiology findings in a prospective series of patients with chronic constipation. METHODS: A total of 155 consecutive patients with chronic constipation underwent anorectal manometry, electromyography (EMG), the balloon expulsion test, colonic transit-time study, and defecography. RESULTS: All investigations were completed by 134 patients (112 females) with a median age 52 (range, 17-79) years. Patients were categorized on the basis of transit time and pelvic-floor function as belonging to 1 of 4 groups: slow-transit constipation (STC) (delayed transit time but normal pelvic-floor function, n = 28), pelvic-floor dysfunction (PFD) (pelvic-floor dysfunction and normal transit time, n = 32), combined slow transit and pelvic-floor dysfunction (STC + PFD) (n = 27), and normal-transit constipation (NTC) (normal transit time and normal pelvic-floor function, n = 47). There was no difference between diagnostic groups in anal sphincter pressures. However, rectal sensitivity to balloon distension was lower (P < 0.05) in patients with delayed transit. Paradoxical puborectalis contraction (PPC) was found on EMG in 42 patients (31%). The prevalence of PPC was higher (P < 0.001) in patients with pelvic-floor dysfunction. Inability to evacuate the rectal balloon was reported by 37% of patients with pelvic-floor dysfunction and 12% of patients with normal pelvic-floor function (P < 0.001). Rectocele was the only anatomic abnormality at defecography which was associated with poor rectal emptying. CONCLUSIONS: About two-thirds of our patients with constipation had objective evidence of delayed transit or

BACKGROUND: Chronic constipation is one of the most common disorders in Western countries and despite numerous clinical, pathophysiologic, and epidemiologic studies its cause is still unclear. Several hypotheses have been proposed and according to experimental studies and clinical observation, fiber intake could play a role in its pathogenesis. The purpose of this case-control study was to examine the possible correlation of idiopathic chronic constipation in children and dietary intake, particularly fiber intake. METHODS: A randomized sample of children (291 children with constipation and 1602 controls) aged 2 to 14 years was taken from three of the 52 counties of Greece. Stratification was performed on the basis of urban, rural, or suburban location and socioeconomic status. The nutritional data were obtained from a 3-day dietary record and a dietary history. Statistical analysis was performed with multivariate tests, multivariate analysis of variance, discriminant analysis, and chi-square analysis according to the characteristics of the correlated variables. RESULTS: Constipated children had a lower caloric and nutrient intake (p < 0.001), lower body weight/height (p < 0.001), and higher prevalence of reported anorexia (p < 0.001). Discriminant analysis indicated that dietary fiber alone was independently negatively correlated with chronic constipation, despite the age and the age of onset of constipation. Relative risk also had a negative correlation with fiber intake (p < 0.001). Of the main fiber fractions only cellulose and pentose were independently correlated with chronic constipation. CONCLUSIONS: Lack of fiber may play an important role in the etiology of chronic idiopathic constipation in children.

OBJECTIVE: Our aim was to retrospectively analyze the Mayo Clinic experience of descending perineum syndrome from 1987-1997. METHODS: Clinical records were abstracted for demographic features, risk factors, results of anorectal and defecation tests, and a mailed questionnaire evaluated outcome and current symptoms. RESULTS: All results are mean +/- SD. Clinically, 39 patients (38 women, one man), mean age 53+/-14 yr, presented with constipation (97%), incomplete rectal evacuation (92%), excessive straining (97%), digital rectal evacuation (38%), and fecal incontinence (15%). Laboratory tests showed anal sphincter resting pressure was 54+/-26 mm Hg, and squeeze pressure was 96+/-35 mm Hg; expulsion from the rectum of a 50-ml balloon required > 200 g added weight in 27%; perineal descent was 4.4+/-1 cm (normal < 4 cm) by scintigraphy. Scintigraphic evacuation, rectoanal angle change during defecation, and perineal descent were abnormal in 23%, 57%, and 78% of the patients, respectively. Associated features included female gender (96%), multiparity with vaginal delivery (55%), hysterectomy or cystocele/rectocele repair (74%). On follow-up, 64% responded; 17 of these 25 responders underwent pelvic floor retraining. At 2-yr median follow-up (range, 1-6 yr), 12 still experienced constipation or excessive straining; their perineal descent was greater than in patients who responded to retraining (p = 0.005). CONCLUSIONS: Descending perineum syndrome is identifiable by clinical history and examination, and the most prevalent abnormality on testing is perineal descent > 4 cm; rectal balloon expulsion is an insensitive screening test for descending perineum syndrome. Pelvic floor retraining is a subopti
