Input: Twenty one randomised trials with a total of 1371 children met the inclusion criteria. Sample sizes were generally small. All studies but one investigated children with functional faecal incontinence. Interventions varied amongst trials and few outcomes were shared by trials addressing the same comparisons. Combined results of nine trials showed higher rather than lower rates of persisting symptoms of faecal incontinence up to 12 months when biofeedback was added to conventional treatment (OR 1.11 CI 95% 0.78 to 1.58). This result was consistent with that of two trials with longer follow-up (OR 1.31 CI 95% 0.80 to 2.15). In one trial the adjunct of anorectal manometry to conventional treatment did not result in higher success rates in chronically constipated children (OR 1.40 95% CI 0.72 to 2.73 at 24 months). In one small trial the adjunct of behaviour modification to laxative therapy was associated with a significant reduction in children's soiling episodes at both the three month (OR 0.14 CI 95% 0.04 to 0.51) and the 12 month assessment (OR 0.20 CI 95% 0.06 to 0.65). There is no evidence that biofeedback training adds any benefit to conventional treatment in the management of functional faecal incontinence in children. There was not enough evidence on which to assess the effects of biofeedback for the management of organic faecal incontinence. There is some evidence that behavioural interventions plus laxative therapy, rather than laxative therapy alone, improves continence in children with functional faecal incontinence associated with constipation.
Output:

This review identified 21 studies with a total of 1371 children. Behavioural interventions when used together with laxative therapy may improve continence in children with non-organic faecal incontinence and constipation whilst biofeedback does not add any long-term benefit. Children who received biofeedback treatment had not always been evaluated beforehand for the suitability of the treatment. There was not enough evidence to assess the effects of biofeedback in children with organic faecal incontinence.
