Anal Incontinence



Anal incontinence (AI) is the involuntary loss of either flatus or stool and a socially awkward and underreported diagnosis. A detailed history and physical examination are indicated for evaluation of incontinence. Diagnostic testing modalities include anorectal manometry, electromyography, pudendal nerve terminal motor latency, endoanal ultrasound, and defecography, along with scoring systems to rate the severity of incontinence and resulting quality of life indicators. Patients with AI should be educated on maintaining anal hygiene. Conservative measures include dietary modification, pharmacologic agents, and bowel management regimens. Mild AI is managed through pelvic floor exercises or biofeedback therapy. Those with intact sphincters and weak pudendal nerves are suitable for sacral nerve stimulation. Defective sphincters are managed through sphincteroplasty or an artificial bowel sphincter. Some require a colostomy to control incontinence. Treatment is best individualized.
