Management of Fecal Incontinence: Etiology, Diagnostic Approach, and Conservative Therapy

Fecal incontinence is a common problem especially in the elderly resulting in a reduced quality of life.

The etiology of fecal incontinence is often multifactorial with little options for a causal therapy. The mechanisms causing incontinence can be detected by sophisticated methods in most of the patients. Using therapeutic algorithms, incontinence can be improved or even continence restored in many patients.

Diagnostic work-up starts with history, digital investigation, and anoproctoscopy. The specialist will further investigate with anorectal manometry, anal endosonography, and electromyography of the external anal sphincter muscle. Nonoperative therapy comprises hygienic methods, medical therapy, intraanal electrostimulation, and training methods like pelvic floor exercises or biofeedback. Second-line conservative therapies are tibial nerve stimulation, transanal irrigation, or anal inserts.
