Fecal incontinence: evaluation and treatment.

Fecal incontinence, the involuntary passage of gas, liquid, or solid stool, is an underreported problem in our society. The evaluation of fecal incontinence includes a focused history, physical examination, and assessment of the pelvic floor musculature. This article describes the assessment of fecal incontinence, focusing on specific diagnostic tests designed to identify dysfunction of the anal sphincter and adjacent pelvic floor musculature and on the use of these tests in determining an appropriate treatment plan.
