Anorectal malformations (ARM), occurring approximately 1 in 5000 live births, mainly involve the distal anus and rectum, but also sometimes the urinary and genital tracts. Defects range from the minor and easily treated with an excellent functional prognosis, to those that are complex and often associated with a poor functional prognosis. Despite the better knowledge of the anatomy and physiology and the improvement of surgical management after birth, fecal and urinary incontinence can occur, due mainly to deficient nerve supply. A few studies and clinical practice have shown that disease-specific problems of ARM have an effect on somatic function, mental health and psychosocial functioning.
