[Constipation in children].

Constipation in childhood is often unrecognized and diagnosed upon manifestations such as pain and pseudo-diarrhoea reflecting of a fecalith. It is sometimes complicated with urinary infection and can be a factor favouring enuresis. In the absence of deterioration in the general condition, it reflects modification of the propulsive functions of the colon or of the reservoir function of the rectum. In a such context, no further explorations are required. Treatment involves dietary recommendations such as good nutritional balance and sufficient fibre intake as well as mineral-based laxatives (paraffin oil) or nonabsorbable osmotic sugars. Enemas and suppositories should be used in case of stool withholding. Sphincter reeducation by biofeedback is indicated in child over 8 years of age after failure of medical therapy.
