[PDF] Fecal Incontinence in the Elderly: FAQ | Semantic Scholar

Anorectal manometry, anal endosonography, magnetic resonance imaging, pudendal nerve latency, and electromyography provide morphologic and physiologic assessments of the internal and external anal sphincters that provide clues to the pathophysiology of fecal incontinence and may help to guide medical, surgical, or biofeedback therapy.

Diarrhea is the most common aggravating factor for fecal incontinence, and antidiarrheal medications such as loperamide and diphenoxylate or bile acid binders may help, while patient characteristics which influence choice of treatment include mental status, mobility impairment, and typical bowel habits are studied.
