Fecal Incontinence

Fecal incontinence is a socially devastating clinical condition. Initial symptomatic treatment includes exclusion of foods that precipitate the problem, increased use of fiber, and drug therapy with loperamide. Persistence of incontinence after these lifestyle modifications requires the physician to evaluate the internal and external anal sphincters. Anal endosonography and manometry provide an evaluation of sphincter structure and function. If an isolated muscle defect is seen, sphincteroplasty can be tried. If this surgical procedure is not indicated, biofeedback may be an option. Biofeedback should be considered for patients with neurogenic fecal incontinence, a weak but structurally intact external sphincter, or a decreased ability to perceive rectal distention. Muscle transposition to create a neosphincter should be offered only by surgeons with extensive experience performing this surgery. Because of the cosmetic sequela of colostomy, this surgery is often considered as a last-step procedure, despite being safe and effective.
