Fecal incontinence: a practical approach to evaluation and treatment.
Fecal incontinence is a common problem and can have a major impact on the quality of life of those affected. Various disease processes affecting stool consistency, rectal sensitivity, or the anal sphincters can cause fecal incontinence. Obstetric trauma is now known to be a major cause of sphincter dysfunction. The evaluation of the patient with incontinence helps to determine the choice of therapy-medical or surgical. The two most important tests are anorectal manometry, which provides information on sphincter pressures, and rectal sensation, and anal endosonography, which is currently the test of choice for defining the anatomy of the anal sphincters. The choice of therapy depends on the etiology of incontinence, the anatomy of the sphincters, and also on the effect of incontinence on the quality of life of the patient. Control of diarrhea, regardless of the cause, should be attempted first. Biofeedback therapy is effective in the majority of patients and is particularly attractive because it is safe and well tolerated. Surgery is offered when medical therapy is unsuccessful or when the etiology is thought to respond best to surgery, such as in postobstetric trauma. Sphincter repair, for treatment of selective sphincter defects, is the best surgical option. Neoanal sphincters and implanted artificial sphincters are far less attractive because of technical difficulties and low success rate.
