[Idiopathic constipation in children. Value of treatment by biofeedback].

Anorectal manometry was used in the training by biofeedback of children with idiopathic constipation. Fourteen children 7 to 12 years old with outlet obstruction due to sphincteric disorders were submitted to a biofeedback session. There was a good improvement in 10 of the 12 children who accepted this treatment. This result is in agreement with the data published in literature. This complementary treatment appears useful when it is well accepted by the parents and the child and when the manometric signal is well understood by the child who must be also able to apply the technique at home.
