BACKGROUND: Barium defecography can assess structural and functional abnormalities in patients with chronic constipation. OBJECTIVE: The purpose of this study was to determine the prevalence of individual and overlapping defecographic findings in this setting. DESIGN: This was a cross-sectional study. SETTINGS: The study was conducted at a university hospital tertiary GI physiology department. PATIENTS: Consecutive examinations of 827 consecutive patients presenting over a 30-month period with well-defined symptom severity (≥12 points on the Cleveland Clinic Constipation score) were included. Systematic evaluation of images with results stratified by sex is described. MAIN OUTCOME MEASURES: Six individual functional or anatomic (intussusception, rectocele, enterocele, megarectum, excessive dynamic perineal descent) defecographic observations were defined a priori, thus permitting 26possible combinations of findings (ie, 63 abnormal types + 1 normal). RESULTS: Patients with constipation (mean symptom score = 19) were predominantly female (88%), with median age of 49 years (range, 17-98 y). All 6 individual radiologic findings were identified with a total of 43 combinations found in the cohort; the 14 most prevalent of these accounted for >85% of patients. Only 136 patients (16.4%) had a normal defecography (34.3% males vs 13.9% females; p < 0.0001). Overall, 612 patients (74.0%) had structural (n = 508 (61.4%)) or functional (n=104 (12.6%)) abnormalities in isolation, with 79 (9.6%) others exhibiting combinations of both. Functional abnormalities in isolation were more common in males compared with females (22.5% vs11.2%; p = 0.025) as opposed to structural abnormalities (57.8% vs 85.7%; p < 0.0001). Expulsion time was longer in females compared with males (110 s (60-120 s) vs 90 s (60-120 s); p = 0.049). LIMITATIONS: The study was limited by its lack of multiorgan opacification. CONCLUSIONS: These results provide a contemporary atlas of defecographic findings in constipation. Several individual structural and functional features have been systematically classified, with overlap greater than previously acknowledged and profound differences among sexes that carry implications for tailoring management.
