TABLE 3.
Response to BF according to Rome III Criteria and etiology subgroups. Functional defecation disorders of all etiologies responded to BF therapy, whereas isolated structural outlet obstruction (e.g., rectocele >4 cm, intussusception extending into the distal anal canal, prolapse beyond the anus, obstructive enterocele with retained contrast at the end of straining) did not. Statistics: Frequency (%).
