The etiology, assessment, and treatment of fecal incontinence.

Fecal incontinence is a common symptom that often impairs quality of life. It is generally caused by a variety of conditions that are associated with anorectal sensorimotor dysfunction and/or diarrhea. Assessment should be tailored to age and symptom severity. Modulation of disordered bowel habits is the key to management; biofeedback and surgery might also be beneficial.
