Fecal continence and quality of life were evaluated by a questionnaire in 83 adult patients (mean age, 35 years; 53 women, 30 men) who underwent surgery for a low anorectal anomaly between 1947 and 1963. Fecal continence was assessed by a score described by Holschneider. Seventy-eight healthy people with similar age and sex distributions were used as controls. All controls had good fecal continence, 76% with completely normal bowel function. The aberrations in anal function found in 24% of the controls were minor, such as constipation or occasional slight smearing. Only 60% of the patients who had a low anorectal anomaly had good continence and completely normal bowel function was observed in 15%. Male patients had a slightly better outcome than females. Social problems related to deficient fecal control were reported by 39% of the patients. In addition, 13% of the patients had difficulties in sexual functions. Other health problems were reported by 52% of the patients. Social or sexual problems associated with anal function were not reported by the control population; 6% of them had other health problems. The present controlled study shows that at the adult age, a significant proportion of patients with low anorectal anomalies suffer from deficient fecal control and a diminished quality of life.
