Abstract
ABSTRACT: Functional fecal incontinence (FI) is a worldwide problem in children and comprises constipation-associated FI and nonretentive FI. Irrespective of pathophysiology, both disorders impact negatively on the psychological well-being and quality of life of affected children. A thorough clinical history and physical examination using the Rome IV criteria are usually sufficient to diagnose these conditions in most children. Evolving investigations such as high-resolution anorectal and colonic manometry have shed new light on the pathophysiology of functional FI. Although conventional interventions such as toilet training and laxatives successfully treat most children with constipation-associated FI, children with nonretentive FI need more psychologically based therapeutic options. Intrasphincteric injection of botulinum toxin, transanal irrigation and, in select cases, surgical interventions have been used in more resistant children with constipation-associated FI.
