Pelvic floor dysfunction

Abstract

Pelvic floor dysfunction results from a defect in coordinated evacuation of fecal residue from the rectum. Numerous pseudonyms have been used to describe this disorder: anismus, pelvic floor dyssynergia, obstructed defecation, and outlet obstruction. A history of prolonged straining before successful elimination or application of perineal or vaginal pressure or digital disimpaction to achieve defecation suggests pelvic floor dysfunction. However, because constipation is the most common complaint of patients with pelvic floor dysfunction, pelvic floor dysfunction must be differentiated from other causes of constipation, such as colonic inertia and irritable bowel syndrome.
